Manzoni Bianco (Incrocio Manzoni 6.0.13) - Benaco Bresciano, Lombardy, and Vignetti Delle Dolomiti, Trentino, Italy

Most countries that have an established wine industry also tend to have oenology and viticulture research programs which have a number of different aims.  In general, these programs are responsible for carrying out research to try and improve the wine quality within a given country.  At one time, grape breeding was a big part of this particular mission.  Many of the French hybrid grapes were created in an effort to combat the phylloxera louse, while many of the German crossings (such as Sheurebe, Kerner and Dornfelder, among others) were created in an effort to match individual grapes with various aspects of the difficult German climate.  In the United States, much of the work done in grape breeding was done by Harold Olmo at UC Davis (who created Symphony, Emerald Riesling and Early Muscat), though the University of Cornell has released a few grapes (like Chardonel) as have some private breeders like Elmer Swenson (who created St. Croix).  The one huge wine power who seems to be missing in this story is Italy.

Italy does have research institutions throughout the country devoted to grape research, but grape breeding has never really been their focus.  There are specific Italian crosses, but they aren't as well known or as widely spread as those efforts from other countries for a variety of reasons.  The primary reason is that Italy is embarrassingly rich in native grape varieties with several hundred approved for use and an estimated several thousand actually spread throughout the country. Another big reason for the lack of Italian crossings/hybrids is that Italy does not have the same challenging climates as countries like Germany or the USA and so there wasn't and isn't any real need to develop new varieties that could survive.  Furthermore, even some of the more difficult climates in Italy have been growing grapes for hundreds of years that are native to the area and thus already adapted to the local weather systems.  In short, why would you need to create any new grapes when you have so many varieties close at hand and when you have climates that are essentially tailor-made for the growth of vines?

One of things that makes us human, though, is our inability to accept the limitations that nature has laid upon us.  Yes, we have many excellent grapes that grow well in our climates, but surely we can do better?  It was in that spirit that Professor Luigi Manzoni began his work in grape breeding at the Viticulture and Oenology School of Conegliano in the Veneto region of Italy.  Manzoni, who lived from 1888 until 1968, was involved in many different kinds of research on the vine, and one of the areas he was experimenting in was grape breeding.  He was not the only grape breeder active in Italy (see also Bruno Bruni, creator of Incrocio Bruni 54), but he was perhaps the most successful.  His aim was to try and create new varieties for the Veneto that were of higher quality than those already being cultivated, but which would also yield more prolifically and be more disease resistant.  Manzoni was not the only grape breeder active in Italy (see also Bruno Bruni, creator of Incrocio Bruni 54), but he was perhaps the most successful.

Manzoni created many different crossings throughout his career, but as with most grape breeders, only a few have had any lasting importance.  He created Manzoni Moscato by crossing Moscato di Amburgo and Raboso, Manzoni Rosa (or Manzoni 1.50) by crossing Trebbiano and Traminer, and Incrocio Terzi N.1 by crossing Barbera with Cabernet Franc.  Two of his most famous red grapes are known as Incrocio Manzoni 2-14 and Incrocio Manzoni 2-15, and both are supposedly made by crossing Glera and Cabernet Sauvignon, but a recent study (citation 1) seems to indicate that 2-15 is actually a crossing between Mathiasz Janosne (Mathiasz 210) and Kövidinka.  Many of these grapes are grown in commercial quantities in northeastern Italy, but just barely.

The most famous Manzoni creation, though, is almost certainly Manzoni Bianco, or Manzoni 6.0.13.  Manzoni created this grape at some point in the early 1930's supposedly by crossing Pinot Bianco and Riesling.  Wine Grapes indicates that this parentage was disputed by a few Italian authors who believed that the grape was actually a Chardonnay and Riesling cross, but Vouillamoz assures us that his DNA research shows that the given pedigree is correct (I do not have access either to the original dispute or to Vouillamoz's DNA data, so I suppose I'll take his word for it).  You may be surprised to learn that Manzoni Bianco is currently the 13th most widely planted grape in all of Italy with nearly 24,000 acres devoted to it.  It is permitted in a few DOCs in the Veneto and in Trentino, but most of the plantings are actually further south in Calabria, Puglia and Molise where it is likely used for bulk wine production.

I was able to track down two wines featuring the Manzoni Bianco grape.  The first was the 2009 Pratello "Lieti Conversari," which I picked up from my friends at the Spirited Gourmet for around $25.  This wine is 100% Manzoni Bianco from the Brescia region of Lombardy.  The grapes for this wine are hand harvested and 80% are fermented in stainless steel while 20% are fermented in oak barrels for 3-4 months (it is unclear whether it is new oak or not, but the wine didn't taste oaky to me at all and I would have guessed this saw 100% stainless steel).  In the glass the wine was a medium lemon gold color.  The nose was moderately intense with aromas of white peach, green apple, pear and grapefruit.  On the palate the wine was on the lighter side of medium with fairly high acidity.  There were flavors of grapefruit, lime, racy green apple, pear and white peach.  It felt like there was still a slight prickle of CO2 to the wine as well, but since it didn't really dissipate, it was probably just an effect of the acidity.  It was bright and zippy, despite the fact that it clocked in at a pretty hefty 14% alcohol.  I found it lithe, vibrant and very enjoyable overall.  Fans of snappy high acid whites will find a lot to like here, but be careful as it wears the 14% alcohol well and it can sneak up on you.

The second wine that I tried was the 2010 "Fontanasanta" from Elisabetta Foradori, which I picked up for around $28 from my friends at the Wine Bottega.  This wine is 100% Manzoni Bianco from the hills above Trentino that is left in contact with its skins after crushing for about a week in large, egg shaped cement containers (there's a biodynamic reason for this that I don't really buy, so I'll just leave it at that).  The wine is then aged for 12 months in acacia casks prior to bottling.  In the glass the wine was a medium bronze gold color.  The nose was moderately intense with aromas of pear, toasted almond, honey, red apple and lemon peel.  On the palate the wine was medium bodied with medium acidity.  There were flavors of ripe apple, pear, almond, honeysuckle flower, pineapple and a touch of apple cider. It's difficult to imagine two wines more different from one another than the two I tried for this tasting.  The Foradori was deep, rich and honeyed with lovely cidery notes and bit of oxidative tang.  What it lacked in vibrancy and freshness, it made up for in depth and complexity.  It's difficult to say which wine is "better" since both were clearly made to be such different things.  In the spring and summer months, I'd probably reach for the Pratello, but in the cooler fall and winter, I'd definitely go for the Foradori.  Both are very good, very interesting wines that really show what Incrocio Manzoni is capable of in careful hands.

Teroldego - Trentino and Tuscany, Italy

I'm going to confess something: I'm kind of a geek.  I guess anyone who has read more than one of my posts probably could have figured that out, but I'm just going to come right out and say it here.  Part of why I love writing this website is that it gives me an outlet for the kind of geekery that I can't really let fly in my everyday life.  I love doing the research and learning about the minutiae of these unusual grapes.  I love exploring the nooks and crannies of the wine world to try and find hidden treasures and cool stories.  Today, for example, I was doing a little bit of background reading to get ready to post about Teroldego when I stumbled across an article in the journal Heredity called "Geneaology of Wine Grape Cultivars" (full citation: Vouillamoz, J., & Grando, M. (2006). Genealogy of wine grape cultivars: ‘Pinot’ is related to ‘Syrah’. Heredity, 97(2), 102-110).  I know, this dry, academic reading is what most people use to get through a particularly vicious attack of insomnia, but I love this stuff.  My day job is also at a big time research university, so I have full access to a lot of these journals.  Anyway, I started to read this article and it's talking about how for many years, scientists would look at the leaf shape of different grape varieties to try to determine the relation between different cultivars.  Needless to say, this was a very inexact science.  Recent progress in the field of genetics has allowed scientists to use genetic markers to identify parentage and sibling relationships between all these different grapes with much greater accuracy and with many interesting surprises (I'll spare you the excruciating details, but the method is similar to the method that forensic scientists use on DNA samples at crime scenes).  So I'm reading through this article and then looking through the references and picking up new articles and I look up and I've got 5 articles printed out in front of me and I figure it's probably time to stop and get to the matter at hand.

So, Teroldego, then.  It appears that there may be a sibling relationship between Teroldego and the Pinot family and there is likely a parent/offspring relationship between Teroldego and Lagrein and Marzemino (**UPDATE** Teroldego is definitely one parent of Lagrein, while the other is Schiava Gentile, according to: Cipriani, G. et al.  The SSR-based molecular profile of 1005 grapevine (Vitis vinifera L.) accessions uncovers new synonymy and parentages, and reveals a large admixture amongst varieties of different geographic origin.  2010.  Theoretical and Applied Genetics.  121: 1569-1585.).  It also turns out that Teroldego is a full sibling (meaning it has the same two parent vines) to a grape called Dureza, which is one of the parent grapes of Syrah.  This is interesting in light of a comment from Jim Clendenen of Au Bon Climat winery in California which is quoted in Oz Clarke's Grapes and Wines.  Clarke has Clarendon saying that California should have planted Teroldego rather than Merlot and Barbera and, furthermore, it is his belief that if Teroldego were planted on the slopes of Crozes-Hermitage rather than Syrah then the wine there would be greatly improved. Bold talk indeed.  Au Bon Climat is primarily a Pinot Noir producer and their terroir isn't necessarily conducive to the Teroldego grape, but I believe that they do have a little Teroldego under vine (according to Eric Asimov of the NYT), though I don't know if they actually bottle and sell any of it (there is no mention on their website).  It is possible in California to blend up to 25% of other grape varietals into a single-varietal bottling in California without mentioning it on the label, so its possible that they could use those grapes for that purpose.  Some California producers are notorious for adding high color wines like Syrah to their Pinot bottlings for added color and depth so it wouldn't necessarily surprise me, but I'm certainly not going to accuse the winemaker of doing that based on a hunch and some anecdotal evidence.

Teroldego's home is Trentino in the Trentino-Alto Adige region of Italy.  We've spent a little time in the Alto Adige visiting with Schiava.  Trentino is the southerly portion of this region where the Germanic/Austrian influence isn't quite as pronounced.  There are references to Teroldego from Trentino mentioned as far back as the 15th Century. The grape is well suited to warm weather, which may seem a little odd for northern Italy, but they have some areas in the valleys and river basins where the grape can get all the sun and warmth that it needs.  It is a thin-skinned variety that produces a deeply colored wine, somehow.  There are competing theories about the origin of the name of the grape.  I've read that a court in Vienna once called the wine "The Gold of the Tyrol," and somehow that ended up as "Teroldego."  I've also read that it has more to do with the wire harnesses, or "tirelles" used to trellis the vine.  Matt Kramer, in his Making Sense of Italian Wine contends that that the name derives from the Gernman word teer which means "tar," a flavor which Teroldego can sometimes take on.  Take your pick, I guess.

The first wine that I was able to try was the 2005 Teroldego Rotalino (the official DOC name of the region in Trentino where most Teroldego is grown, named for the gravelley river bottom plain called Campo Rotalino near the Adige river) Riserva from Mezzacorona.  I was able to pick this up from my friends at Bin Ends for about $20.  In the glass, the wine was a dense purple ruby color nearly all the way to the rim.  The nose was full of smoky black cherry and black plum with some blackberry and blueberry.  On the palate, the wine was close to full bodied with fairly high acid and very little tannin.  The grape can be tannic in its youth, but at 6 years out, most of that seemed to be pretty well integrated.  There were flavors of black plum, smoky earth, tart cherries and stewed blackberries.  The wine was much fruitier and exciting on the nose than on the palate.  The finish is kind of abrupt as the fruit really falls off rather than fade away.  People have mixed feelings about the age-ability of Teroldego, and after this bottle, I can understand the misgivings. 

Talk to people familiar with the grape and they'll tell you that Teroldego grows in Trentino and nowhere else; in fact, Bastianich and Lynch (in their Vino Italiano) quote Elisabetta Foradori, one of the leading producers of Teroldego in Trentino as saying "you can't find it anywhere in the world."  Well, somebody forgot to tell Poggio al Casone.  This estate grows Teroldego and bottles it under their "La Cattura" label with a little bit of Syrah added to it (the bottle I had was 90% Teroldego and 10% Syrah, but their website currently lists the blend as 85/15).  I picked my bottle up from the Gypsy Kitchen for about $16.  The wine was a deep purple ruby color in the glass and had aromas of black cherry and black plum with a bit of stewed black fruit and a smoky, meaty kind of aroma that I'm guessing may be from the touch of Syrah.  On the palate the wine was close to full bodied with medium acidity and soft, well-integrated tannins.  There was lush black cherry and plum fruit flavors grounded with some savory earthy notes and a nice long, evolving finish.  This wine was the better of the two and really shows what Teroldego is capable of.  It's very similar in style to a northern Rhone wine for a fraction of the cost of what many of those bottlings would run you.
