One of the biggest differences between winemaking in Europe and the United States is that wine made in Europe is made following a protocol established by and for the geographically identifiable area the wine is made in, while wine made in the United States is made with near complete freedom.A Mendocino County wine might be Chardonnay or Malbec. Napa Valley is likely to contain Cabernet Sauvignon, but could instead contain Sangiovese. Russian River Valley wine bottles could be Pinot Noir or Semillion. In the United States, we have to label our wines with the grape varietal, because there is no rule, rhyme, or reason about what each area can put into the bottle.When you buy a bottle of Bordeaux at the wine shop, you know which grapes the wine can be made from based on long established historical protocol, and you can have a solid expectation of style, based on every other Bordeaux wine you have ever purchased. Same for Burgundy, Tuscany, and Chianti.Identified DOCG in Italy Denominazione di Origine Controllata e Garantita (controlled designation of origin guaranteed), AOC in France, – appellation d’origine contrôlée (controlled designation of origin), or other assurance of area protocol control, when you pick up a European wine, your expectations are based on where the wine came from.In the United States, there is no similar geographically identifiable area making wine following a protocol – almost.Unique in the entire United States is the Coro Mendocino program, established by a collaborative group of winemakers known as the Consortium Mendocino.Every time you hold a Coro Mendocino wine, from any vintage, from any winery, you are holding something with connections to every other Coro Mendocino wine ever made.Every Coro Mendocino wine is made from 100 percent Mendocino County grapes, by a Mendocino County winery, in the county, and contains Zinfandel first and foremost, between 40 percent and 70 percent, with no single blending grape varietal exceeding the percentage of Zinfandel used. Blending grapes come from a list of varietals historically grown in Mendocino County alongside Zinfandel, and are typically either Italian varietals – Sangiovese, Dolcetto, Charbono, Barbera, and Primitivo, or Rhone varietals – Syrah, Petite Sirah, Carignane, and Grenache.Each winery is also allowed up to 10 percent free play, where a single unlisted varietal may be added to the blend. In the last 10 years, I can think of two wines that took advantage of the “free play” to add some Cabernet Sauvignon.Chemistry limits (sugar, acid and pH), use of oak barrels, and both barrel and bottle aging are also addressed by the protocol to assure a somewhat uniform expectation of style within the Coro Mendocino program.Each Coro Mendocino wine undergoes rigorous quality tasting trials. Initially, the wines are tasted up to four times by the participating winemakers who make and share notes of constructive criticism in an effort to see each wine reflect the high quality standards embodied by Consortium expectations.A Selection Panel of five members of Consortium Mendocino – at least three being participating winemakers – conducts a pass/fail qualifying selection tasting. Pass, and you get to label your wine Coro Mendocino and sell it proudly beside every other Coro Mendocino made at $37. Fail and you’ve got nothing. You don’t have Coro and, without the minimum 75 percent needed, you don’t have Zinfandel. John Cesano’s “Random Red” wouldn’t likely sell for $37 or have the cachet a wine labeled Coro Mendocino has.On Saturday, June 22, Consortium Mendocino will release the 2010 vintage Coro Mendocino wines at a 10th Anniversary Release Party at the Little River Inn. The 2010 vintage was produced by 10 wineries: Brutocao, Claudia Springs, Fetzer, Golden, McFadden, McNab Ridge, Mendocino, Parducci, Philo Ridge, and Ray’s Station.A five course meal prepared by chef Marc Dym begins with a passed appetizer course, paired with a white or sparkling wines from each Coro winery, the remaining courses are seated; the three middle courses each feature three or four of the Coro Mendocino wines, grouped by weight, lighter, medium, and heavier, and paired with gourmet dishes. The final course is dessert and paired with your favorite of the 10 tasted Coro Mendocino wines.Tickets are for couples, include the five course meal and the first tastes of each of the 2010 vintage wines, and a full set of all ten Coro Mendocino wines. The cost is $500 for a couple ticket and, with the 10 bottles of wine plus a five course dinner with wine for two, is a bargain. I attended last year, and wrote quite favorably about the experience.This year, in celebration of the 10th anniversary of Coro Mendocino, there will also be an exclusive V.I.P. tasting of Coro 1.5L magnums, on the night before the release party. Limited to the first 30 release party guests that reserve a spot at $75 per person, Coro wines from the last 10 years, and by producers current and past, will be opened and enjoyed from 4:30 6:30 p.m. on Friday, June 21.To secure your seats at the release party dinner, and possibly the magnum tasting too, call the Little River Inn at (707) 937-5942.
