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 (TTB).
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 lack of steeply sloped hills reduces the risk of erosion and facilitates mechanical tiling and harvesting in the vineyards.
However, Los Olivos District AVA is located about 30 miles (48 km) inland from the Pacific Ocean, so much of the marine fog has diminished by the time it reaches the area in the late afternoon.
Soil nutrient levels are adequate to produce healthy vines and fruit without promoting excessive growth.
