September: California Wine Month • Second Part
Staff Writer - September 19, 2007

With the growth of the California wine industry, distinctive wine regions have emerged and have been officially defined, allowing consumers to know the origin of the grapes used to produce specific wines.

The naming of the wine regions, which in the US are called American Viticultural Areas (AVAs), is managed by the TTB (Tobacco Tax and Trade Bureau). Currently there are 107 AVAs in California, which are distinguished by their geographic, climatic and historic characteristics. In addition, counties or entire states, such as California itself, are considered appellations, as the AVAs are generically known.

As for the Italian denomination of origin (DOC, DOCG, IGT), or the French appellations, the US AVAs do not guarantee a superior qualuty of the product, but rather let the consumer know what kind of product to expect, based on the characteristics of the place where the grapes were grown. The AVA system can be seen as a guideline for wine lovers who want to taste the terroir, to say it with the French.

In California there are five main wine production areas, Northern California Coast, Central California Coast, Sacramento / San Joaquin Valleys and Sierra Foothills, Sierra Nevada, and Southern California, which include the majority of the states AVAs.
