Los Olivos District AVA is an American Viticultural Area located in Santa Barbara County, California established on January 20, 2016, by the Alcohol and Tobacco Tax and Trade Bureau . It straddles the Santa Ynez Valley, formed by the Santa Ynez River, between the Purisima Hills above Solvang. The area encompasses the townships of Los Olivos, Ballard, Santa Ynez and Solvang. State Route 154, known locally as the San Marcos Pass Road or Chumash Highway, bisects the region accessing many of the wineries and vineyards as it traverses toward its destination in Santa Barbara.
The Los Olivos District stretches over 35.66 square miles (22,820 acres) where approximately twelve bonded wineries and forty-seven commercially-producing vineyards cultivate 1,120 acres (450 ha). The district shares its western boundary with the eastern border of the Ballard Canyon AVA and its eastern boundary flanks the western perimeter of Happy Canyon of Santa Barbara AVA while not overlapping either AVA. It is located within the Santa Ynez Valley viticultural area and the larger, multi-county Central Coast viticultural area. The USDA plant hardiness zone for the AVA is 9b.
