The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes the 34,155-acre "Paulsell Valley" viticultural area (AVA) in Stanislaus County, California. The Paulsell Valley viticultural area is not located within, nor does it contain, any other established viticultural area. TTB designates viticultural areas to allow vintners to better describe the origin of their wines and to allow consumers to better identify wines they may purchase.
