The AVA is the United States' watered-down version of France's wine-industry regulatory system, the Appellation d'Origine Contrô̂lé́e, or AOC. It was created in 1983 with the central purpose of guaranteeing that at least 85% of the grapes used to make an AVA-registered bottle of wine come from the specified American Viticultural Area. For example, if a bottle of Kenwood Pinot Noir says "Russian River Valley" on its label, at least 85% of the grapes used to make the wine must have come from the Russian River Valley region. Other AVAs include Napa Valley, Sonoma Valley, and sub-AVAs such as Chalk Hill within the Russian River Valley. The problem is that an AVA really tells the wine buyer very little, because grapes grown at one end of a region as enormous and varied as Napa Valley may have little or nothing to do with those harvested 25 miles away, though also in Napa Valley. It also fails to mention which grape varieties are grown and the winemaking methods used (all of which are governed by law in France via its AOC to assure quality). In short, the AVA reveals almost nothing about the quality of the wine, just where its grapes were grown. Who defines the boundary of an AVA? The Bureau of Alcohol, Tobacco, and Firearms.
