The Alcohol and Tobacco Tax and Trade Bureau (TTB) is expanding the approximately 33,380-acre "Sta. Rita Hills" viticultural area in Santa Barbara County, California, by approximately 2,296 acres. The established viticultural area and the expansion area are both located entirely within the larger Santa Ynez Valley viticultural area and the multicounty Central Coast 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.
