In Santa Barbara County, the east-west orientation of the coastal mountains forms valleys opening directly to the Pacific Ocean. This unique topography allows the flow of fog and ocean breezes to shape distinct microclimates, perfect for the cultivation of classic grape varietals and world class wines.

The 50 miles stretch from Point Conception to Rincon constitutes the longest east-west traverse of shoreline from Alaska to Cape Horn. Here, the Santa Ynez and San Rafael Mountains form a unique coastal range - the inland flow of fog and ocean breezes make the region one of the coolest viticultural areas in California. This means that the fruit has an unusually long "hang time" on the vine, allowing it to fully develop the acids, flavors and tannins needed to produce wines of distinctive character.

Within Santa Barbara County there are three distinct appellations: Santa Maria Valley, Santa Ynez Valley, and Sta. Rita Hills. In addition, the Los Alamos Valley region, between the Santa Maria Valley and Santa Ynez Valley appellations, remains a strong and successful grape growing region. Slightly less than half of the grapes grown in Santa Barbara County are used by local vintners, with the balance are exported to wineries outside the area.
