The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes the approximately 22,820-acre "Los Olivos District" viticultural area in Santa Barbara County, California. The viticultural area is located within the Santa Ynez Valley viticultural area and the larger, 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.
