Clairette - Côtes du Rhône, France

Hello everyone and welcome to what will almost certainly my final post of 2012.  This is my 117th post of the year, just barely surpassing last year's total of 112 posts, and I hope that people have found them interesting and informative.  I'd like to send 2012 off by taking a look at the Clairette grape, which I thought would be relatively easy to find a bottle of, but which turned out to be more difficult to track down than I had thought.  There were about 6,000 acres of Clairette planted in France as of 2009, but this number has been declining dramatically over the past half century.  Plantings stood at almost 35,000 acres in 1958, but they were down to around 7,500 acres by the 1990's.  It is also grown to a limited extent in Italy (where, oddly enough, it is permitted in the blend for Nuragus di Cagliari), Australia and South Africa with a few hundred acres under vine in each of those countries..

The reason for Clairette's recent decline can mostly be chalked up to changing fashions.  Clairette is a very low-acid grape that has a tendency to oxidize very easily.  There was a time when white wines were expected to be a little (or a lot) oxidized, and when those characteristics were prized by consumers and connoisseurs, Clairette was a much more popular grape.  Furthermore, these characteristics also made Clairette popular for the production of Vermouth, but as the popularity of that particular drink has declined, so has the popularity of Clairette.  In today's world, Clairette is typically used as a blending grape and it is often paired with higher acid grapes like Picpoul de Pinet or with Grenache Blanc, Roussanne and/or Marsanne.  Clairette usually contributes aromatic elements and softness to the final blend when it is used.  There are a handful of appellations where Clairette is required to be the dominant or the sole grape in the blend and nearly all of them have the word "Clairette" right in them for convenience.  Clairette de Die, Clairette de Bellegarde and Clairette de Languedoc are probably the most common, but there's also Coteaux de Die and, somewhat surprisingly, Crémant de Die, which is a sparkling wine made predominantly from Clairette grapes.

References to a grape called Clairette can be traced back to the 16th Century, but it isn't clear whether this is the same grape that we know as Clairette today.  Clairette means something like "light white," and could conceivably have referred to many different grape varies through the years.  There's a bit of confusion even today, as Ugni Blanc is sometimes known as Clairette Ronde in some parts of the Languedoc (though the two grapes are not related to one another).  The Erbaluce grape in Italy has a similar etymology, and this study done in 2001 found that the two grapes shared 50% of their alleles at the microsatellite loci investigated, but further testing has not been done to see whether the two grapes are really related to one another genetically or merely linguistically.  There is also some evidence that suggests that Clairette may be related to Airén and/or Roditis, but further study needs to be done to determine just what the relationship might be.

I searched for well over year for a varietal Clairette wine, but was unable to find one.  I eventually picked up a bottle of the 2011 Jean-Luc Colombo "Les Abeilles," which is 80% Clairette and 20% Roussane, from my friends over at Brookline Liquor Mart for around $14.  In the glass the wine was a pale silvery lemon color.  The nose was intense with aromas of peach, grapefruit, melon, white flowers and lime.  On the palate the wine was medium bodied with fairly low acidity.  There were flavors of grapefruit and pear along with a touch of grassy herbaceousness and a stony mineral finish.  The flavor profile was broad and fat with a little bit of bitter citrus pith on the finish as well.  The nose was really lovely, but the lack of acid kind of sunk this for me.  The grassy flavor reminded me of Sauvignon Blanc, but it lacked the energy and vitality that really nice Sauvignon Blanc based wines have.  If you're not really into high-acid white wines, then this is probably right up your alley, but if you're an acid freak like me, then you won't find very much to like here.

Roter Veltliner - Niederösterreich, Austria

I suppose when you decide to write about a grape called Roter Veltliner, it's probably best to go ahead and address the elephant in the room before going any further: no, Roter Veltliner is not related to Grüner Veltliner (or at least not very closely).  This seems difficult to believe given the similarities of their names, but in 1998, an Austrian research team was able to show that not only were Grüner Veltliner and Roter Veltliner not related to one another, but further that Roter Veltliner actually seems to be the more important of the two cultivars in terms of genetic history and parentage (citation 1 below).  Today I'd like to take a closer look at the Roter Veltliner grape and its little family circle.

Grüner Veltliner is certainly more widely available, widely grown and widely hailed than Roter Veltliner, but it has very limited family connections with other Austrian grape varieties.  Grüner is the offspring of Savagnin/Traminer and an obscure grape called St. Georgen-Rebe, which was discovered in an overgrown patch in an abandoned lot in Austria (source).  If there are any other grapes that Grüner has a first-degree relationship with, I have not come across them in any of the literature.  Roter Veltliner, on the other hand, is a key part of what is commonly known as the "Veltliner family," which Grüner is actually not a member of.  The family relationships break down like this:

- Roter Veltliner crossed with Savagnin to create Rotgipfler (which makes Rotgipfler and Grüner Veltliner half-siblings since they share Savagnin as a parent)
- Roter Veltliner also crossed with Silvaner (which is itself an offspring of Savagnin and Österreichisch weiß) to create Neuburger and Frühroter Veltliner
- Frühroter Veltliner was crossed with Grauer Portugieser (which is the pink-berried form of Blauer Portugieser) to create Jubiläumsrebe

Wine Grapes reports that Roter Veltliner likely crossed with a close relative of Traminer/Savagnin to create Zierfandler, but the paper that they cite for support for this doesn't seem to mention Zierfandler at all (though it is in German, and I could be missing it [link immediately begins to download PDF]).  Furthermore, in the 1998 paper referenced above, the authors specifically say "in contrast to previous assumptions...no close genetic relationship between Rotgipfler and Zierfandler could be detected."  If the two grapes shared a common parent, you would expect them to have between 50 and 100% similar DNA, but this study indicates that they could find no such similarity between the two.  The lead author on the Wine Grapes referenced paper is actually also an author on the 1998 paper mentioned above (as well as the lead author on a follow-up paper in 2000, citation 2 below, which also doesn't mention Zierfandler but which traces the Veltliner family tree pretty thoroughly), so it seems odd that he'd not include those findings in either of the papers I've cited but would in the German paper cited by WG.  Since I can't find any published results which show a first degree relationship between Zierfandler and Roter Veltliner or Rotgipfler, and since the papers I've read certainly would have performed the analysis to check for a relationship, I feel OK in saying that there probably isn't one.

Some of you may still be puzzling over the fact that there is no relationship between Roter Veltliner and Grüner Veltliner despite their similar sounding names.  Since Grüner means "green"(and Grüner's berries are green)  and Roter means "red" (and Roter's berries are red) we should be able to find some link between the two grapes through the word "Veltliner," right?  Unfortunately, it isn't totally clear just where the "Veltliner" part of the name comes from.  Many believe that it comes from the word "Veltlin," which is the German word for "Valtellina," which is a valley in northern Lombardia in Italy that borders Switzerland.  The story goes that Grüner Veltliner was named for this valley because it was introduced from there by the Romans.  The problem with this is that the name only seems to  appear in print after 1855 and prior to that, the grape was called Weißgipfler or Grüner Muskateller (despite the fact that it is not related to the Muscat family either).  If the Veltliner were a reference to a Roman origin, it should be traceable further back than that through the historical record, but it doesn't seem to be.  This piece gives some interesting history, but it seems that the answer to the origin of the Veltliner name is still a mystery (though it is worth nothing that all of this research was done for Grüner and not Roter Veltliner, which is apparently not popular enough to warrant this kind of scholarship on its own).

Grüner Veltliner is easily the most widely planted grape in Austria, covering just over 42,000 acres of land in Austria.  Roter Veltliner, by contrast, is only planted on about 640 acres in Austria and is in fact more widely planted in Slovakia, where it covers nearly 900 acres of land.  As you might expect, wines made from it are considerably harder to find than wines made from Grüner, but I was able to find a bottle of the 2009 Ecker Eckhof Roter Veltliner from my friends at the Spirited Gourmet for around $20.  In the glass the wine was a medium silvery lemon color.  The nose was fairly intense with lemon and lime citrus aromas along with some green apple and a touch of apricot.  On the palate the wine was medium bodied with fairly high acidity.  There were flavors of lemon, green apple, lime peel, and lees with a mouthwatering, stony mineral finish.  It was bright, zippy and tart but with nice body and complexity as well.  I thoroughly enjoyed it and found myself disappointed that there weren't more examples around that I could try.  It's definitely something I'll be keeping an eye out for in the future.

Altesse/Roussette - Jongieux, Savoie & Montagnieu, Bugey, France

It's kind of hard to believe that it's been almost two years since I wrote about the Jacquère grape from Savoie and the Mondeuse grape from Bugey in the eastern Alpine regions of France, but it's true.  It is also true that I haven't written any other posts on wines from those two regions since those first two (though I did write the section on Savoie for the AG Wine iPhone/iPad app).  The reason is pretty simple: these are small regions in France that not only don't make very much wine, but also don't export very much either.  They're big skiing areas that attract a lot of tourists, and much of the local production is consumed within the region by the tourists and the locals.  Jacquère is getting a bit more common on US shelves, but it's not becoming a mainstream wine by any stretch of the imagination.  It's much more difficult to find wines made from some of the other grapes from these regions, but I was recently able to try three different wines featuring Altesse, which is also known as Roussette, so I'd like to talk a little bit about that grape today.

Though it is found almost exclusively in Savoie and Bugey in eastern France, Altesse has long been suspected of being an import from somewhere further east.  Its first mention in print is in 1774, and the story given at that time was that the vine was brought to the region from Cyprus by one of the local princes.  The name Altesse means "highness," and it was long thought that this name came from the fact that some royal or noble person brought the vine to the area from somewhere else.  I would have assumed that "highness" was a reference to the altitude of the Alpine vineyards in the area and not to the stature of its alleged importer, but that explanation seems to have been a bit too pedestrian for some early historians.  Wine Grapes gives at least four different explanations that have been scattered through the literature which purportedly give an account of how and when Altesse came to the vineyards of Savoie with dates varying between the 14th and 16th Centuries.  Some say the grape came from Cyprus, while others say it came from Turkey.  In the latter part of the 20th Century, the great French ampelographer Pierre Galet suggested that the vine actually came from Hungary, and, further, may actually be the same as Furmint, since he believed it did not appear to bear any relationship to any other French cultivars.

It looks like Galet, and most of the early historians, were probably wrong about Altesse, though.  While I can't find any specific paper directly comparing the two grapes, the VIVC database does have DNA profiles for both Altesse and Furmint, and it's pretty clear that they're not only different grapes, but also probably not even that closely related.  Wine Grapes says that Altesse is actually more closely related to Chasselas, and if you speak (or read) French, you can read a little bit about that here.  Chasselas is thought to be native to the area around Lake Geneva, which sits right on the border between France and Switzerland and which is just northeast of Savoie.  If Altesse is closely related to Chasselas, and Chasselas is essentially native to the region, then it stands to reason that Altesse is also likely native to the region, and is not an import from some exotic eastern land.

Altesse is also known as Roussette in many places because the grapes begin to take on a reddish hue as they ripen and the French word for reddish hue (or russet-colored) is rousse.  It is particularly susceptible to a variety of fungal infections (both downy and powdery mildews as well as botrytis).  Altesse is found most often in the Roussette de Savoie and the Roussette de Bugey AOCs, which are in Savoie and Bugey respectively, as you may have guessed.  There are a few village names that can be appended to either AOC, and it used to be the case that wines labeled with a village name needed to be made from 100% Altesse, while wines simply carrying the Roussette de Savoie/Bugey label could have up to 50% Chardonnay added in.  This practice is no longer allowed, and all wines labeled either Roussette de Bugey or Savoie must now be 100% Altesse.  As of 2008, there were almost 900 acres of Altesse in France and just a little bit in Switzerland (compared to the nearly 2500 acres of Jacquère in France).

I was able to try three different wines featuring the Altesse grape.  The first was the 2009 Famille Peillot Altesse from Bugey, which I picked up from my friends at the Wine Bottega for about $18.  The wine is from the village of Montagnieu, which is one of the villages allowed to append its name to its wines.  In the glass the wine was a pale silvery lemon color.  The nose was reserved with a little bit of pear and chalk, but not much else.  On the palate the wine was on the lighter side of medium with fairly high acidity.  There were flavors of lime peel and light lime citrus along with some white pear, green apple, a touch of pineapple and chalk.  It had the hallmark clean, fresh flavors, zippy acidity and solid minerality that I associate with Alpine wines and it had them in spades.  It was lithe and nervy and was a real pleasure to drink.  It represents an excellent value at only $18 and was still drinking very well after sitting in my cellar for over a year (I do sometimes lose things down there).  I found myself wondering how much different an Altesse wine might be closer to the vintage year, so when I came across a 2011 wine, I snapped it up.

I picked up the 2011 Domaine Eugene Carrel Roussette de Savoie from my friends at the Spirited Gourmet for about $17.  This wine is from the village of Jongieux, which is a village that can add its name to Vin de Savoie wines, but not to Roussette de Savoie wines (there is a separate cru designation called Marestel that can be added to the label for Roussette de Savoie, but this wine doesn't appear to be from that particular area of the village).  In the glass the wine was a medium lemon gold color.  The nose was fairly intense with fresh cut lemon, white pear, green apple, lime peel and chalk.  On the palate the wine was medium bodied with medium acidity.  There were flavors of banana, pear, lemon, green apple and a touch of lees with a strong, stony mineral finish. The banana is much more present as the wine warms up, though it does eventually blow off a little bit.  The nose was much more intense on this wine than on the previous one, but I thought it was a bit flabbier on the palate and wasn't quite as focused.  It's still a very nice wine for the money, but if I was forced to choose between the two, I'd reach for the wine from Bugey most of the time.

The final wine that I tried was a little bit different.  It was the 2010 Côtillon des Dames from Jean-Yves Péron in Bugey, and it was an orange wine made from a combination of Altesse and Jacquère grapes.  I picked this wine up from my friends at the Wine Bottega for about $25.  In the glass the wine was a medium orange/amber-bronze color and was a little cloudy.  The nose was fairly intense with honey, peach, honeysuckle flower, orange and pink grapefruit aromas.  On the palate the wine was medium bodied with high acidity and a light tannic grip and maybe just a slight tickle of CO2.  There were flavors of peach, grapefruit, honeysuckle and Meyer lemon along with a slight oxidative cidery tang.  The flavors were rich and intense, but also nicely fresh and citrusy.  The nose was just gorgeous and it was a little difficult to move past it and actually drink the wine.  Once I did, though, I found it lithe and electric as the citrus fruits really danced around the bright nervy acid core.  This was definitely my favorite of the three Altesse wines I tried, though it's not exactly a traditional bottling.  If you come across it, though, give it a shot as it's a really fantastic bottle.

Çimixà (Scimiscià) - Colline del Genovesato, Liguria, Italy

Though most of the wines I write about on this site are things that I've come across on my own, I do occasionally receive tips from readers about interesting grapes and wines they've come across that I might also be interested in.  One of my more prolific tipsters is Tony from Pennsylvania who, in addition to providing a tasting note for my post on Nuragus, also has a sharp eye for unusual wines.  He has previously pointed me to Albarín Blanco and Tempranillo Blanco, but the grape he directed me to for today's post is definitely more obscure than either of those.

A few months ago, Tony asked if I had ever heard of a grape called Çimixà from Liguria.  Çimixà was definitely a new one on me, and a cursory glance on the internet revealed virtually no information the grape.  I saw that Bisson, whose wines I had featured in some prior posts, and whose portfolio seems to be pretty well represented in the Boston area, made a varietal Çimixà, so I set about trying to track a bottle down.  I asked around locally to see if anybody could get their hands on some, and came up empty.  Not only that, but none of the guys I asked about ordering the wine had ever even heard of it, and these guys are pretty tough to stump.  I was now getting more and more anxious to get my hands on a bottle.  Tony pointed me in the direction of MCF Rare Wine in New York City, who had about half a dozen bottles in stock and who was willing to sell a bottle to me (all legally, of course).

Though I pulled the cork on my bottle a month or so ago, I've been quietly dreading having to write this post because, as I mentioned above, I wasn't able to find any information at all about Çimixà when I had previously searched online, and a new Google search didn't really get me very much new information either.  I went to look the grape up in Wine Grapes, and began to get despondent when I didn't see an entry under Çimixà, so I checked the index and found that it was listed under the name Scimiscià.  I know I was a little harsh on Wine Grapes in my review of that book, and I still stand by my criticisms, but it is really an excellent reference work and is very helpful for situations just like this one.  Their entry on the grape indicates that it is one of those grapes (like Pugnitello or Nascetta or Pecorino, etc) that was on the brink of extinction, but was rescued by a gentleman named Marco Baciagalupo, a pastry chef from Genoa, Liguria.  In the 1970's, Marco gathered together about 500 vines that were purported to be Çimixà and planted them all together in a single plot.  A local cooperative took over the job of caring for these vines in the 1990's, and by 2003, the grape was included in the national register of varieties in Italy.

Eagle-eyed readers may note that the picture I've included with this post is for a grape called Genovese, and not Çimixà or Scimiscià.  The reason for that is that a study done in 2009 found that the Scimiscià of Liguria was not only the same as the grape known as Frate Pelato in the Cinque Terre, but was also the same as the Genovese of Corsica.  It had been suspected that the Corsican Genovese was actually either a local curiosity or was identical to the Bianchetta Genovese/Albarola or the Bosco of Liguria, but this team was able to show that none of these hypotheses were true.  Though the three grapes share some morphological similarities, it doesn't look like any of them have any first degree relationships with one another, though Bosco and Albarola appear to be more closely related to one another than either is to Scimiscià.

The last published agricultural census for Italy was carried out before Scimiscià was added to the national register of varieties, so there currently is no figure on total plantings of the grape in Italy (though one imagines that the total is probably pretty minuscule).  According to this site, the Çimixà and Scimiscià names are dialectical variants of one another, and both refer to bedbugs because the vine apparently has these spots on it that look like bedbug bites, which is not very appetizing at all.  Under the name Genovese, Scimiscià can be found in some Corsican wines, but is pretty much used as a blending grape there.  As Frate Pelato, the grape is occasionally used in the blends of the Cinque Terre.  There are a handful of Ligurian producers making varietal wines from the grape, and nearly all of them use either the Çimixà or the Scimiscià name for their products.

Bisson chooses to use the Çimixà name on their label, though the wine itself is called "L'Antico."  I paid about $30 for my bottle from MCF Rare Wine in New York.  I am not sure whether any Italian DOC allows for a 100% Çimixà wine, but this was bottled as an IGT, so it's not really a problem.  In the glass the wine was a medium lemon gold color.  The nose was moderately intense with lovely, delicate aromas of peach, pear, lime, white flowers and chalk.  On the palate the wine was on the lighter side of medium with medium acidity.  There were flavors of apricot, lime peel, ripe pear, and golden apple with some chalky minerality on the finish.  The wine was subtle, delicate and elegant and was really just lovely to drink.  It's not a wine to lay down, though, and it had completely unraveled by the next day, but while it held together, it was very pretty.  It is a bit on the expensive side, as many wines from Liguria tend to be, but it's a really unique drinking experience and I don't feel slighted by the price at all.

Vidal Blanc - Massachusetts and Finger Lakes, New York, USA

Vidal Blanc is either a grape you've never heard of or a grape that you can't get away from, depending on where you live and, to some extent, how you shop.  Here in the cold northeastern United States, Vidal is seemingly everywhere, but only if you go to the local wineries to sample their wares.  It is still difficult to find on store shelves in the Boston area, and if you do run across one in your local shop, chances are it's a Canadian ice wine.  I've made many visits to most of the wineries in Massachusetts and to many others throughout New England, though, and I came across so many Vidal Blanc based wines that, for awhile, I thought that perhaps Vidal Blanc wasn't really a fringe grape.  I was surprised, though, when I saw some of the planting statistics for the grape.  Canada certainly leads the way in Vidal plantings at nearly 2,000 acres, much of which is ultimately used to make ice wine, but I was shocked to learn that Virginia actually leads the way in US plantings of Vidal at 150 acres,* followed closely by Michigan  (145 acres) and Missouri (118 acres) before dropping off precipitously to 35 acres in Indiana and 32 in Illinois.  Clearly the vine isn't quite as ubiquitous as it seemed to me, so I decided to write about the Vidal Blanc grape itself and a few local wines that I've come across recently.

Vidal Blanc was created in 1930 by Jean-Louis Vidal, a French grape breeder who was trying to create new grapes for Cognac production.  Jean-Louis created Vidal Blanc by crossing Ugni Blanc (aka Trebbiano Toscano, one the grapes still most commonly used to make Cognac) with Rayon d'Or, which is itself a hybrid created by our old friend Albert Seibel by crossing two other Seibel hybrid grapes together (Seibel 405 & 2007, for those filling out your pedigree charts at home).  Jean-Louis Vidal created several thousand different grapes throughout his career, but Vidal Blanc has definitely been the most successful and is easily the most widely cultivated grape bred by him.  Even though the grape was created in France by a French breeder, it is virtually non-existent there today.

Vidal Blanc came to the New World, or at least to Canada, in 1945, when a man named Adhémar de Chaunac imported 35 French hybrids (one of which was Vidal Blanc) and four vinifera varieties into Canada.  De Chaunac was the technical director at TG Bright winery in Niagara Falls, and he was looking for new grapes to grow at his winery other than the foxy native American varieties that had been widely used to that point in Canadian wine history.  Most plantings with vinifera varieties had not gone well, as they were generally unable to tolerate the harsh Canadian winters, so De Chaunac was hoping to find some cold hardy varieties in this group that could withstand the difficult climate and still make European-style wines.  Test plots were planted and wine making trials began and by the 1960's, the hybrid grapes that showed the most potential were gaining ground in the Canadian planting statistics.  Maréchal Foch, Seyval Blanc, Verdelet, De Chaunac and Vidal Blanc were the most popular, and many of those grapes are still somewhat widely planted throughout Canada.

Vidal Blanc is perhaps best known for the ice wines created from it in many parts of Canada and the northeastern United States.  As mentioned in my post on an ice wine made from Cabernet Sauvignon in Canada, true ice wines are made from grapes that are left on the vine well after the regular harvest and allowed to freeze there.  The frozen grapes are harvested in the dead of night (to prevent their thawing) and are pressed while still frozen.  What happens when a grape freezes is that much of the water in the grape turns to ice, but most of the sugar doesn't freeze, so when you press the frozen grapes, the solid ice stays behind, but a concentrated, sugary syrup comes out.  This syrup is then partially fermented, since it is impossible to convert all of that sugar into alcohol, and the result is a rich, lusciously sweet wine.

It may seem like a simple thing to just leave some grapes on the vine and harvest the frozen juice, but not all grapes are suited to making good ice wine.  First of all, the grapes need to stay on the vine a very long time, and as grapes hang on the vine and ripen, they tend to lose their acidity.  Acidity is key in sweet wines, though, since without it, wines just taste syrupy and cloyingly sweet.  Secondly, the longer grapes hang on the vine, the greater the chance that they can be damaged either by diseases such as molds or mildews, by insects or birds, or just from the wind and weather.  Thick grape skins help protect grapes while they are waiting for the first freeze to arrive, so while thin-skinned varieties like Semillon are valued for the production of botrytised sweet wines (since their thin skins allow the botrytis to more easily infect the grapes), thick skinned varieties are preferred for the production of ice wines.  Vidal Blanc happens to have thick skins and relatively high acidity, which makes it an ideal grape for ice wine production.

When I visited the Finger Lakes region of New York a year or so ago, I picked up a bottle of the 2009 Vidal Ice from Standing Stone Vineyards for about $25 for a half bottle.  This is not a true ice wine, since the grapes were picked and then later frozen before ultimately being pressed.  In the glass it was a light tawny gold color.  The nose was fairly intense with aromas of honey, dried apricot, quince, baked apple and pineapple.  On the palate the wine was on the fuller side of medium with fairly high acidity.  It was lusciously sweet with flavors of honey, apricot, baked pineapple, and orange creme with a bright, zippy vein of tart green apple running through it.  It was dense and rich, but it was also lively and snappy thanks to the fresh acidity.  I found it really well balanced and enjoyed it an awful lot.  I've bought Vidal Blanc based ice wines from Canada before and have paid almost $100 for half bottles of some of them, so at only $25 per half bottle, this is a tremendous value.

In his Wines of Canada (which I've used extensively throughout this post), John Schreiner gives the following quote about Vidal Blanc from the CEO of the Canadian wine powerhouse Vincor, Donald Triggs: "Vidal is in that magical area of not making a really great table wine but a phenomenal Icewine."  While Canada tends to focus on making ice wine from their Vidal grapes, most American producers make dry table wines from theirs, and I was able to pick up a few local examples recently and test whether Triggs' assessment of its potential as a table wine grape was accurate or not.

The first bottle that I tried was the 2010 Vidal Blanc from Running Brook Vineyards in North Darthmouth, Massachusetts, which set me back about $13.   Running Brook was founded by Pedro Teixeira and Manuel Morais, both of whom spent much of their separate childhoods in the Azores islands of Portugal.  Manuel started his first vineyard in 1975 and was one of the first people to grow grapes commercially in New England.  Pedro was actually his dentist and the two quickly realized that they both shared a passion for the vine and wine and decided to go into business together.  They opened Running Brook Vineyards in 1998, according to their website, though their labels say "Est. 2000."

In the glass, this wine was a medium lemon gold color.  The nose was moderately intense with pear, banana, grapefruit and honeysuckle flower aromas.  On the palate the wine was on the fuller side of medium with medium acidity.  It was medium sweet with flavors of honeyed pink grapefruit, poached pear, candied pineapple and coconut.  The image that sprang to mind while drinking this wine was a Dole fruit cup, meaning it was fruity and sweet with a variety of flavors going on, but was still kind of flat and ultimately not that exciting.  Fans of simple, sweet white wines will find a lot to like here, especially for the price, but it's not really my thing.

The second wine that I tried was the 2009 Travessia Vidal Blanc, which I picked up for about $10 (not at the winery, but rather at the Bin Ends discount store in Braintree...the 2011 Vidal Blanc seems to cost about $15 at the winery itself).  Travessia is an "urban winery" located in downtown New Bedford, Massachusetts, which is owned by Marco Montez, who also makes all the wine.  Marco doesn't own any vineyards, but rather he buys most of his grapes from Running Brook and from Westport Rivers in Massachusetts.  He does make wine from California and from Washington St. grapes, but he insists that his wines labeled as being from Massachusetts are made with 100% Massachusetts fruit.

In the glass, this wine was a medium lemon gold color.  The nose was reserved with reserved aromas of honey, pineapple and peach.  On the palate, the wine was medium bodied with high acidity.  It tasted off-dry with flavors of green apple, under-ripe pineapple and lime with just a touch of peachiness.  It was somewhat tart with sharp acidity, but I found that I preferred this to the flatter Running Brook wine.  Both were somewhat Riesling-like, but the Running Brook was definitely broader and more generous, while the Travessia was leaner, sharper and more austere.  To some extent, this could be a vintage issue, since 2010 was very hot in Massachusetts, and many wineries found themselves with very ripe grapes.  2009 was a more typical, cooler year, so the grapes probably weren't quite as ripe as in 2010, and as a result, the acidity is a bit higher and the fruits aren't quite as generous.  Whatever the reason, this wine is a great value at only $10, and would still be a good value at $15 as well.

*These statistics are taken from Wine Grapes, which indicates that New York has substantial plantings, but gives no acreage for them.  I haven't been able to find any specific numbers for New York myself, since most sources online only list the top 5 or so hybrid grapes grown in New York, and Vidal apparently doesn't crack that list.  Further, New York seems to measure things in terms of tons of grapes processed rather than acres under vine, so even if I could find a number for Vidal, I'm not sure how enlightening it would actually be.

Colorino - Tuscany, Italy

Colorino is one of those grapes that the average wine drinker has almost certainly encountered, but is probably not aware of it.  Colorino was historically very important in the production of Chianti, and if you've sampled a few different Chiantis in your lifetime, you've almost certainly had one with a little dollop of Colorino thrown in.  Colorino has been a traditional part of the Chianti blend for many years, though it rarely makes up more than 5-10% of the final product.  As you might expect from its name, the primary thing Colorino brings to the table is deep color, which it is able to impart even at such small concentrations.  Its contribution to the Chianti blend has been compared to that of Petit Verdot in Bordeaux, and, like Petit Verdot, some producers have decided to see whether Colorino is interesting enough to make varietal wines from.  I was able to pick one up recently, but before I get into that, let's take a little closer look at the Colorino grape itself.

As mentioned above, Colorino has long been valued for its contribution to the Chianti blend, especially for those producers who utilized the governo method.  In the governo method, some of the grapes harvested in September and October were set aside and not pressed with the others.  These grapes were allowed to dry out for several months before being pressed in mid to late November.  As you might expect, some grapes are able to withstand this drying process better than others, and Colorino is particularly well suited to it.  This concentrated, sweet juice was then added to the vats of juice that had just finished its primary alcoholic fermentation, which caused the fermentation to start up again.  While this had the immediate effect of increasing the final alcohol content, the main reason for this practice was that this second fermentation often kicked off malolactic fermentation as well, which, in the days before bacterial inoculation, was not always so easy to start in a wine made from a high-acid variety like Sangiovese.  The governo process made the wines drinkable much earlier than they otherwise would be, and was more heavily used when Chianti was seen as an easy-drinking, every day/every meal kind of wine.  With the more recent focus on quality and creating age-worthy red wines, the governo process has fallen out of favor.  Colorino continues to be used in the Chianti blend, though, for its ability to lend color to the final wine, and for a time, its popularity began to rise as many producers fought against the increasing presence of Cabernet Sauvignon and Merlot in Tuscan vineyards and wines, though the gradual acceptance of the international varieties in Tuscany has caused its popularity to wane once more.

You may not be surprised to learn that a grape name like Colorino has come to be used for several different grape varieties over the years*.  A study done in 1996 analyzed four different grapes known as Colorino and found that not only were they each different grape varieties, but at least one of them didn't seem to even be related to the other three at all.  The outlier of the group was called Colorino Americano, while the other three were known as Colorino del Valdarno, Colorino di Pisa and Colorino di Lucca.  In 2008, another study (citation 1) analyzed Colorino di Pisa and Colorino di Lucca along with a handful of other Tuscan vines  and showed that the two Colorinos were in fact distinct and possibly have a parent/offspring relationship with one another.  To add to the confusion, the VIVC considers Colorino di Valdarno, Colorino di Lucca and Colorino Pisano to be the same variety and doesn't have an entry for Colorino di Americano at all.  They further list three other Colorinos that are different from the three mentioned above, calling them Colorino Dolce, Forte and Nostrale respectively.  I have not been able to find any other information on these three varieties of Colorino, so I'm not sure how they fit in with the others or even how widely cultivated they may be.  Wine Grapes tells us that the most common variety of Colorino is Colorino del Valdarno, but since it doesn't appear that the Italian authorities differentiate between these vines, any or all of the four (or seven) Colorinos could be present in your bottle.  The latest Italian agricultural census (2000) indicated that there were 436 hectares planted to Colorino, and one assumes that this figure includes the various Colorino varieties altogether.

I was able to find a bottle of the 2005 La Spinetta "Il Colorino" at Panzano in Southborough for around $34.  In the glass the wine was a deep, opaque purple ruby color.  The nose was moderately intense with stewed black cherry, black plum, smoke and charcoal aromas.  On the palate the wine was on the fuller side of medium with fairly high acidity and medium tannins.  There were flavors of black cherry, blackberry, sour cherry and wild blueberry fruits along with some licorice, smoke, char, and earth.  The wine was mostly dark and dense, but it had a nice bit of tart freshness from the sour cherry and blueberry flavors that kept it lively and interesting.  It is often the case that one understands quickly why blending grapes are rarely seen in a starring role when one finds a varietal wine comprised of these grapes, but I had the complete opposite reaction when tasting this wine.  Rather, I found myself wondering why more people wouldn't try to make wines like this, as it was complex, interesting and very tasty to boot.  The price tag looks a little steep at first blush, but I wouldn't have any qualms about paying that amount again for this wine.  I thoroughly enjoyed it and would definitely pick it up again if I ever run across it.

*Some sources have indicated that the Ancellotta of Emilia-Romagna and Colorino are the same grape, but it doesn't look like that's so.  While I wasn't able to find any specific studies that compared the two grapes, a recent study conducted by a French team (citation 2) analyzed over 4000 different grape accessions in a particular collection.  Though there is no table with all of the data shown, a later parentage study (citation 3) by many of the same team members gave a list of the 2300+ grapes used, which was culled from the results of the earlier study.  Ancellotta and Colorino are listed separately, which seems to indicate that they are genetically distinct from one another.  Just which Colorino variety was used, though, is unclear.

Albana di Romagna - Emilia-Romagna, Italy

Though the history of viniculture and viticulture goes back several thousand years, the histories of individual grapes tend to be measure on the scale of hundreds of years at the most.  There are several good reasons for this.  The most important reason is that the craze for varietal wines and the consumer and winemaker focus on individual grape varieties is a very recent phenomenon.  Wines were traditionally given names related to their geography, and the grapes that went into making those wines was of secondary importance at best.  The linking of individual grape varieties with particular places didn't become a legal issue until the last hundred or so years when the various appellation laws began to take effect throughout Europe.  While individual grape varieties may have been associated with famous wine growing regions in the distant past, there was nothing (or very little) forcing any of those growers to continue to grow those grapes in those regions other than tradition.

Another, more obvious reason for the lack of long historical records for individual grapes is that grape names have tended not to be very stable throughout history.  The lands of Europe have changed hands many times over the past few thousand years and each new wave of conquerors brought their own languages and their own attitudes towards wine making and wine drinking.  The mix of materials, languages and cultures made it difficult for a stable vocabulary to develop so even if a particular grape variety has been in continuous cultivation for a thousand years, it would be easy to lose track of it through the historical record as that record shifted from conqueror to conqueror and from language to language.  Throw in the lack of a consistent and thorough historical record for all wine making regions throughout history and the lack of a unified ampelography, and you end up running into a lot of trouble when you try to trace an individual grape very far back through the written histories.

Some grapes do have long historical roots, though, and Albana is one of them.  The first written record of a grape known as Albana comes to us from a work written in 1305 AD.  Pietro de Crescenzi, a Medieval agricultural writer, writes of Albana that it makes "a powerful wine with an excellent taste."  You can find some variation on this theme in just about any source you pick up that mentions the grape, though I've often wondered how anyone can be sure that the grape called Albana 700 years ago is the same as the grape currently known by that name.  This becomes an even more troubling question when you take a look at the two etymological reasons given for the grape's name.  The most common reason given is that the grape's name comes from the Latin word alba, meaning "white," and it was given its name because of its exemplary stature in comparison with other white grapes.  The second explanation for the grape's name is that it was originally cultivated around the Alban Hills of Lazio and was named for them*.  Both explanations seem to allow for the possibility of a lot of confusion with similarly named grapes, and I would be very surprised if it turned out that Crescenzi's Albana and ours were the same grape.  Since there's probably no way to say for sure, though, we should probably just note our skepticism and move along.

What we can say for sure about Albana is that it is an important piece of the Garganega family tree.  Garganega is the great white grape of Soave, and recent studies have shown that it has a parent/offspring relationship with a staggering number and variety of grapes throughout Italy.  One of those grapes is Albana, though Garganega also has a parent/offspring relationship with Catarratto, Trebbiano Toscana and Malvasia di Candia, among others.  What is really shocking about these findings is the geographical dispersion of these grapes, as they can be found from the Veneto in the northeast to Emilia Romagna in the center-west, all the way down to the island of Sicily in the south.  It isn't clear whether Garganega is the parent to all of the varieties listed or whether one of them is one of its parents, which means that Albana is either a grandparent to the others (if it happens to be a parent to Garganega), or is a half-sibling to them and possibly a grandchild of one.

As you might expect from a grape purported to be as old as Albana, there are many different clonal variants of the grape currently cultivated.  The most common one is known as Albana Gentile di Bertinoro, but Wine Grapes lists at least five other clonal varieties as well.  They also hint that some of these could actually be seedlings of Albana and thus not technically clones but rather separate varieties, but no evidence, DNA or otherwise, is provided to back this up.  Albana's curious claim to fame is that it was actually the first wine promoted to DOCG status in Italy in 1986 with the establishment of the Albana di Romagna DOCG (a decision which is universally considered to have been politically rather than qualitatively made).  There are currently nearly 7,000 acres of Albana under vine in Italy as of 2000, which is down from around 11,000 as of 1990.  Albana wines run the gamut stylistically from light table wines to sparkling wines to sweet passito style wines.

I was able to try two different Albana-based wines, one in the dry table wine style and another in the passito style.  The first was the table wine, which was the 2009 Umberto Cesari "Colle del Re" Albana di Romagna, which I picked up on a recent trip to Pennsylvania in one of their state stores for around $15.  In the glass the wine was a medium silvery lemon color with greenish tints.  The nose was moderately intense with green apple, lime and grapefruit citrus aromas, along with just a hint of leesy funk.  On the palate the wine was medium bodied with medium acidity.  There were flavors of white peach, green apple, lime and juicy ripe pear along with a hint of beeswax and lees.  The flavor profile was broad and generous, with a little bit of citrus to rope it in.  I would have appreciated a bit more acid to it, as without it I thought the wine was a little bit bland.  The blurb description of the grape in Wine Grapes calls it an "inherently neutral Italian variety" which I thought was a pretty accurate description, but then it goes on to say that it " can produce very good sweet wines," so I decided to pull the cork on my passito wine to see how it fared.

The second wine that I tried was the 2003 Umberto Cesari "Colle del Re" Albana di Romagna Passito, which I picked up from my friends at Marty's for around $40 for a 500 mL bottle.  In the glass the wine was a reddish tawny-amber color.  The nose was fairly reserved with some date, raisin, burnt sugar and toasted nut aromas.  On the palate the wine was on the fuller side of medium with fairly high acidity.  It was very sweet with flavors of dried cherry, raisin, date, scorched brown sugar, walnut and maple syrup.  I was surprised at how bright and zippy the wine was given the lackluster acidity in the table wine I tried, but the acid was bright and vibrant here and really made the wine dance on the palate.  It was sweet, nutty and very tasty, but the price tag did feel a little steep.  It was definitely a more interesting and complex wine than its table wine compatriot, and if these two bottles are representative, then I would agree with the assertion in Wine Grapes that the sweet wines made from this grape are really the place to go for the best Albana experience.

*There is apparently yet another possible explanation, given by this site, which says that the grape name comes from its resemblance to the straw colored hair of a Roman empress named Albana.  I've not seen this explanation elsewhere and though I like it more than the other explanations, I feel that it's probably the least likely.

Book Review - Wine Grapes, by Robinson, Harding & Vouillamoz

When I first learned about the impending publication of the massive Wine Grapes, I was both excited and a little nervous.  I was excited because it looked to be just the kind of thing that could help me a lot in doing research for this blog, but at the same time, I worried that its publication would make me obsolete.  The book purported to be the ultimate guide to wine grapes, and I worried that everything interesting that could be said about many of the grapes that I try would already be said here and there would be no reason for me to continue with this site.  I pre-ordered the book many months in advance and began the waiting process.  That process ended a few months ago with the release (and delivery) of this massive tome, which I've now had some time to read through and put some thoughts together about.

Those who are unfamiliar with some of my other posts should note that I've had some issues in the past with the crew responsible for publishing this book.  This is the same editorial team that is responsible for maintaining the online version of the Oxford Companion to Wine, and many of the findings from this book were previously published through that venue.  In several of my prior posts, I've noted issues or problems that I've found in the online version of the OCW, some of which I addressed to the editors, but none of which were really satisfactorily resolved.  The first involved their entry on Hondarrabi Zuri (link goes to my discussion of the issue), where they claimed that it was actually the same as the American hybrid Noah, while the second involved their publication of an alternate parentage for Emerald Riesling, which turned out to be correct, but which they refused to divulge their source for.  I'm not going to delve back into either of those topics, as I've said all I card to say in those posts, so interested readers are advised to follow the links and read away.

Before I get into the issues I have with this new book, I do want to start out with a list of the things that I really liked about it.

1) It is gorgeous.  The layout is easy to follow and though there is a lot of information presented for most of the grapes, the book never feels overwhelming.  The slipcase is a nice touch as well and I much prefer the burgundy color for the US publication to the cream color for the UK.

2) Most of what is presented is accurate.  The book is thoroughly researched not only from a scientific standpoint, but from a historical and ampelographical one as well.  Much of the information provided is adequately cited and the bibliography is comprehensive.

3) The scope of the work is astounding.  It claims to be a "complete guide to 1,368 vine varieties," and while I didn't count to make sure they're telling the truth, the 7 pound weight and nearly 1,250 pages would seem to indicate that they are.  There is no other single volume available with more information on more grape varieties than this.  No really serious wine adventurer will want to be without this volume for very long.

4) The signed bookplates that the group gave away was a very nice touch.  All you had to do was email your address to someone affiliated with the publication team and they mailed out a book plate signed by all three authors for you to affix to the inside cover of your tome (for free!).  If you haven't ordered the book yet or haven't yet asked for a signed bookplate, you're probably too late, I'm afraid to say, as they only did a few hundred of them.  I'm happy to have received mine and think it was a nice way for the contributors to thank people for laying out some serious cash for this book.

All that said, there are some issues I have with the book.

1) The color plates.  There are 5 sections within the book that contain 8-10 pages of full color reprints of illustrations from a turn of the century (last century) work of ampelography.  These sections are evenly spaced throughout the book.  They're printed on a different kind of paper that is actually a different size (smaller) than the rest of the pages, and when you try to flip through the book, you inevitably land on one of these sections.  They're nice to look at, but they're completely unnecessary and kind of in the way.  The book retails for $175, and one wonders how much of that they could have shaved off by doing away with these.

2) It is sometimes difficult to find exactly the grape you're looking for.  They put a grape's main entry under its most common synonym in the country that is thought to be its ultimate home.  This is fine for most grapes, but you end up with some weird things like having Carignan listed under Mazuelo, which is a synonym I'm only familiar with in Rioja.  The index is helpful for navigating around this issue (which was probably inevitable given the book's scope), but flipping back and forth in a 1,250 page work is no picnic.  There are some guidepost entries throughout the text that redirect you to the proper name, but these are somewhat erratically placed.

3) The research.  This is my biggest issue, and it's what I'm going to spend the bulk of the rest of this review talking about.  If you don't care about it, feel free to close this browser window now and you'll be welcome back when I get back to reviewing unusual wines in the next few days.

The problems I have with the research for this volume fall into two broad categories.  The first category concerns research done by others that is reported in Wine Grapes.  As I mentioned earlier, most of the information in the book is accurate and is well researched, but there are a few places where the research is either sloppy or inaccurate for personal reasons.

For example, I recently wrote about the Fetească Albă grape from Romania, and in that post I lamented that the OCW mentioned that the long-accepted synonymy between this grape and the Leányka of Hungary was inaccurate, but I had some difficulty tracking down their source for the information since it was only cryptically mentioned and not cited.  This assertion is reprinted in Wine Grapes, and 2 citations are given.  One is the paper that I mentioned in my post on Fetească Albă, which has some serious methodological issues and can hardly be taken to be indisputable (please see that post for more details).  The other is this paper from a Hungarian team, which, while interesting, does not actually say anything at all about the relationship between Fetească Albă and Leányka.  It does say that Leányka and a grape called Leányszolo are not identical, but there is no mention at all of Fetească Albă anywhere in the paper.  Citations are great, but only if the research that you're pointing to actually says what you're claiming it says.

As for the charge of inaccuracies due to personal reasons, the example of Ciliegiolo and Sangiovese provides a nice example.  As mentioned in my previous post on the Ciliegiolo grape, the exact relationship between Ciliegiolo and Sangiovese is contentious.  It is known that the two grapes have a parent/offspring relationship, but there are two different theories as to which is the parent and which is the offspring.  The first was reported by Jose Vouillamoz (and several other Italian scientists) in 2007 and they claim that Sangiovese's parents are Ciliegiolo and a grape called Calabrese di Montenuovo (which Vouillamoz & crew supposedly just stumbled across somewhere in Calabria...it is unclear whether it exists in any holding facilities or even whether any other research teams have been able to obtain a sample to test for themselves, all of which will lead into my final issue in the following paragraph).  The second (authored by Di Vecchi Staraz and others, full citations are in my Ciliegiolo post linked above) shows that Sangiovese and a grape called Muscat Rouge de Madére are the parents of Ciliegiolo.  Vouillamoz's results have not been duplicated by any other group, but Di Vecchi Staraz's findings have been duplicated in at least 2 different studies.  Wine Grapes, whose scientific content was edited by Vouillmoz, presents Vouillamoz's findings as if they were the final word on the matter.  The book does make mention of Di Vecchi Staraz's findings, but dismisses them because they "do not fit with the parentage of Sangiovese (Vouillamoz, Monaco et al 2007)," which is question begging of the worst kind.  The book does note that there were other "discrepancies" in Di Vecchi Staraz's findings, but I've not seen those discrepancies indicated anywhere else, and, as mentioned above, there have been 2 studies in the past year that have shown that Di Vecchi Staraz's analysis is correct.*

All of which brings me to my major second concern with some of the research presented in Wine Grapes, which is that it is private research.  There are many posts where the citation for the information provided is given simply as (Vouillamoz).  Vouillamoz has several publications listed in the bibliography of the book, and when one of them is referenced, the year is always given.  These (Vouillamoz) citations represent something different, though, which isn't ever really fully explained in the text.  Vouillamoz maintains a private DNA microsatellite database with information on various grapes that he has either analyzed in the course of his research, or which may have come from other studies that he has read.  Much of the stuff that the OCW has published, and many of the relationships published in Wine Grapes, were "discovered" by Vouillamoz by sifting through the information in his private database, or by Vouillamoz conducting experiments on his own and publishing the results in Wine Grapes for the first time.

As an example, Wine Grapes publishes that Listán Prieto, aka Mission, and Listán Negro from the Canary Islands are actually two different grapes, despite the fact that they have long been considered to be the same variety. Vouillamoz claims that a "study" has shown that Listán Negro actually has a distinct DNA profile, but his citation is "(Vouillamoz; Jorge Zerolo, personal communication)," neither of which can be called a "study" in any meaningful sense.  The information is presented, though, in a way that makes it seem like the finding has been verified by DNA research (there is an icon in the book, that is probably supposed to look like a double-helix but which just looks like a circle with open semicircles on its top and bottom, used to represent when a synonym or a homonym has been "verified" by DNA studies, and that icon is used here), when in fact it seems that it has only been seen in one non-published "experiment."

Here's the problem with this: it isn't science**.  The information that Vouillamoz chooses to publish in this way may be interesting, but it's wrong to consider these findings "scientific" in any way.  There's a process that people have to go through in order for their ideas to be accepted by the wider scientific community.  That process involves not only performing the experiments and analyzing the results, but publishing them in a peer-reviewed journal as well.  If you read through any of the papers I link to on this site, you'll see that they aren't just a guy asking a question and then announcing that he's answered the question.  The paper goes through the entire set-up for the experiment and shows the data obtained from the experiment described.  This process exists so that other scientists (or anybody, really) can analyze your methodology and your results to see whether your experiment actually can give the kind of information that you claim it can and whether it actually does give the information that you claim it does.  The foundation of good science is reproducibility, which means that others should be able to read your paper and perform your experiments themselves to see whether they obtain the same results as you.  Just publishing findings doesn't fly.  You're not right when you make a discovery; you're right when someone else verifies your results.***

I'm not suggesting Vouillamoz doesn't know what he's doing or that he has fabricated results.  What I am saying is that any information that he provides from private research or from any source that is not a scientific journal is unverified.  My issue isn't the publication of unverified findings, but rather that this information is presented to the reader in such a way that is difficult to separate from the more thoroughly researched findings.  It is given to the reader in a format that very closely resembles properly cited findings, so the lazy reader notes the parentheses and moves on, seeing a citation where none exists.  When citing the published results of others, readers can consult that source and decide for themselves whether the findings seem accurate given the description of the experiment and the publication of the data.  This empty citation, though, leads nowhere and does not even have a corresponding entry in the Bibliography.  It is telling us that Vouillamoz did something, but there's no way for us to see what it was.  By just giving the conclusion for this private research, the book is essentially asking us to take Vouillamoz's word that he did everything correctly and that his experiments and/or his interpretations are sound.  Given some of the issues I've encountered previously in his work, that doesn't feel like a safe assumption to make.

I'm not saying that Wine Grapes is worthless because of these issues.  As I said before, the overwhelming majority of the information in the book is accurate, interesting and informative.  What I am saying is that some of the information they present as if it were scientific fact is not that at all and should be taken with a grain of salt.  I feel that the book could have been better if some of the controversies were more thoroughly explained or if some of the posts had less of the authoritarian air that they carry.  Jose Vouillamoz is a good scientist, but asking a single scientist to compile all of the information for this book was probably not the best idea.  What you get is a single expert's bias, which doesn't produce a very scientific result.

My bottom line is that this book is now my first line of research for pretty much every post I'll write from here on out.  It's an incredible resource that I look forward to enjoying for many years.  But like any first line resource, I'm not going to be content to stop my research there, and I will pursue any questions I have as far as I can, or until I feel that they have been thoroughly answered.  Grape genetics is a rapidly moving field that I enjoy following along on the sidelines.  I think in about another decade, the 2nd or 3rd edition of this work may end up being definitive, but we're just not quite there yet.

**You may argue that I'm missing the point here.  This book is for entertainment purposes and is not intended to be a scientific treatise, you may say.  And you may be right.  But the book is being marketed in such a way and its content is arranged in such a way that the authors clearly want you to think that what they are publishing has been "scientifically proven."  I am arguing that this insinuation is dishonest on their part, as much of the data they are publishing is unproven in a scientific sense. Think I'm overstating their case? The following is the publisher's blurb for Wine Grapes from Amazon.com:

"Using cutting-edge DNA analysis and detailing almost 1,400 distinct grape varieties, as well as myriad correct (and incorrect) synonyms, this book examines grapes and wine as never before. Here is a complete, alphabetically presented profile of all grape varieties of relevance to the wine lover, charting the relationships between them and including unique and astounding family trees, their characteristics in the vineyard, and—most important—what the wines made from them taste like."

Their claim is that they have used "science" or some "science-like substance" to show the truth about many grapes and how they are or are not related to one another.  All I am trying to show is that their methodology isn't always sound, and as a result, some of the conclusions that they reach are hardly as definitive as the confident tone of the blurb and the text itself would lead you to believe.

***As I've pointed out numerous times on this site and a few times in this post, this isn't insignificant stuff (well, it may be in a cosmic sense, but you know what I mean).  Vouillamoz's claim regarding Fetească Albă and Leányka comes from a paper that used samples from a holding facility known to have labeling errors.  This is a methodological issue that requires follow-up research, but we wouldn't know that without the full published paper.  I don't believe that the follow-up research has been done, which only means that the question is currently open until proven otherwise (but if forced to make a decision, you're probably wiser staying away from the findings of a flawed study and opting instead for the belief that the prior hypothesis was correct).  Additionally, Vouillamoz's claim about the relationship between Ciliegiolo and Sangiovese has not been replicated by any other group, and it is unclear whether it can be because of the special nature of one of the purported parents.  If other groups cannot test Calabrese di Montenuovo themselves (and I do not know whether they can or not, but no one else has, as far as I can tell), then we just have to take Vouillamoz's word for it that the grape that he happened to stumble across (he himself says it was "fortuitously sampled") is the long-lost parent of one of the most famous wine grapes in the world. The thing is, we don't have to take his word for it, because we have information from three other publications from three other labs that have all independently shown that Vouillamoz's findings cannot possibly be right, since Sangiovese is itself a parent to Ciliegiolo and is not one of its offspring.  Their methodologies and results relied on grapes and samples that other labs could access and test themselves rather than on one-off field samples and private databases.

UPDATE: I uncovered a bit more on the Ciliegiolo/Sangiovese issue recently, and posted my findings in the comments to this post.  You can read the relevant information here.

Tressallier (Sacy) - Saint-Pourçain, France

A few months ago, in my post on Romorantin, I told the story of a landmark paper that was published in 1999 which showed that many of the grapes currently cultivated in France all shared the same parentage.  One of the parents was Pinot but the surprising finding was that the other parent was a little known and poorly regarded grape known as Gouais Blanc.  Subsequent research (briefly outlined in my post on Menu Pineau) has shown that Gouais Blanc is likely one of the progenitors of nearly 80 different grapes that we know about today, making it easily the most prolific parent that we know of in today's world of grapes.  I bring this up because today's grape, Sacy/Tressallier, is one of those Pinot x Gouais Blanc offspring, making it a full sibling of Chardonnay, Aligoté, Auxerrois, Melon/Muscadet, Gamay and Romorantin.

Because many of the grapes from the Pinot x Gouais Blanc crossing are so well known, there has been a bit of additional research done on the pair and their offspring.  Most notably, in 2009 a group discovered which grape was the father and which was the mother for all of the grapes known to be the offspring of Pinot and Gouais Blanc.  For most species of animals and plants, it is relatively obvious which of the progenitors is the father and which is the mother.  Most animals have clearly differentiated sexes and it is usually easy to tell which animal actually gives birth, making it very easy to spot the mother.  It can be a bit more difficult in plants since many plants are hermaphrodites, but typically, whichever plant produces the seed or the fruit is the mother while the plant that merely provided the pollen is the father.  This works for sexually propagated crops, but vines are clonally propagated and the actual cross that created a given vine likely happened hundreds of years ago in the wild.  Knowing which vine is the father and which is the mother is a much dicier proposition, but it can be done.

Knowing that an offspring receives 50% of its DNA from each of its parents, it may seem impossible to figure out which 50% is paternal and which 50% is maternal.  Furthermore, it may seem irrelevant, since grapevines are hermaphrodites and don't have sex chromosomes, the matter of maternity and paternity seems like a merely academic exercise at best.  This is not entirely true, though.  The DNA of some of the organelles in plant cells, like mitochondria and chloroplasts, are inherited 100% from the mother, which means that the processes that regulate the vine's metabolism are maternally inherited with no input from the father.  In short, this means that the offspring inherits more than 50% of its DNA from its mother, and so for some things, it absolutely matters which vine was the father and which was the mother.  By examining chloroplast DNA (which is maternally inherited), the study mentioned above was able to determine that Pinot was the father and Gouais Blanc was the mother for 9 of the 12 offspring, including Chardonnay, Aligoté, Romorantin, Gamay Noir, Melon and Tressallier (the 3 with Pinot as the mother are the relatively unknown Aubin Vert, Knipperlé and Roublot).

It was long thought that Tressallier actually came into France via Italy, but the discovery of its parentage makes that story very unlikely.  It is now thought that the vine was born somewhere in Burgundy or in northern France.  Its name "Sacy" comes from a village in Champagne, while the Tressallier name is thought to be a contraction of "trans Alligerim," which means "beyond Allier," because it was once planted on the Allier River.  Like its sibling Gamay, Tressallier was once banned, though this time by the mayor of Vermenton (rather than Philip the Bold), who, in 1782, decried it for producing "dull, poor-quality wine."  Though widespread several hundred years ago, its plantings have fallen precipitously lately to only around 12 hectares as of 2008, down from 655 in 1958.  It is authorized for use in the Saint-Pourçain region, which is right in the middle of France, where it is permitted to make up only 20-40% of the blend and is typically blended with Chardonnay or Sauvignon Blanc.  It is also permitted in the production of Cremant de Bourgogne, though it isn't widely used there.

The first wine that I was able to try was the 2009 Calnite Blanc from Famille Laurent a Saulcet, which is about 70% Chardonnay, 25% Tressallier and 5% Sauvignon Blanc.  This bottle was provided to me as a sample from the fine folks at Oz Wine Company.  In the glass the wine was a medium lemon gold color.  The nose was fairly intense with aromas of lemon, golden apples, white flowers, cantaloupe and bread dough.  On the palate, the wine was medium bodied with fairly high acidity.  There were flavors of white pear, golden apple, green melon and a touch of lemony citrus leading to a clean, stony mineral finish.  There was a lot of mouth-watering acidity, but the flavor profile was pretty broad, lacking that zip and zing that I like in my white wines.  This bottle is mostly Chardonnay, and it definitely tastes like it, but it is still a very nice wine.  I'm not sure what this typically retails for, but I think it's in the $20 - $30 range, and it's definitely worth that.  Given the low percentage of Tressallier in the blend, it's not a great way to to get a real sense for the grape, though.

For that, I picked up the 2009 Domaine de l'Orme "Les Grands Vaux" Tressallier.  I picked up this vintage from my friends at Curtis Liquors for about $15, though I've seen the newer vintage (2011) at the Wine Bottega as well.  In the glass, the wine was a medium lemon gold color.  The nose was reserved with some pear and a bit of lime peel, but little else.  On the palate, the wine was on the lighter side of medium with fairly high acidity.  There were delicate flavors of lemon-lime citrus and white peach along with a clean, stony minerality on the finish.  It wasn't terrifically complex, but the flavors were clean and very pure with a wonderfully fresh vibrancy.  It had more of the zip and zing to it that I like, but it was also very well balanced.  I don't have any idea what the grape breakdown is with this wine, because typically when a variety is stated on the label, it must be made from at least 85% of that grape, but it also has Saint-Pourçain on the label, and I thought that the Saint-Pourçain AOC only allowed up to 40% Tressallier.  I've been told that this wine is 100% Tressallier, so that's what I'm assuming, but I can't really find any verification of that online.  In any case, it's a very nice wine, especially for the price, and is the sort of thing you should definitely pick up if you ever run across it.  Tressallier is increasingly difficult to find, but it is capable of making very nice wines.
