The San Diego wine growing region is located on the southern California coast and is served by San Diego International Airport. San Diego may be California's smallest wine growing region but is blessed with the multiple micro climates and rich soils that produce very fine Chardonnays, Cabernets and Zinfandels.

The Southern California Region extends from the Malibu-Newton Canyon AVA, 850 acres, north of the city of Los Angeles to the southern border of California below the city of San Diego. Among the five AVAs located in the region, the South Coast is the largest with an area totaling 115,200 acres. Cucamonga Valley contains 109,400 acres of land. Temecula comprises about 33,000 acres and San Pasqual Valley around 9,000 acres. The region has about 44 wineries.

The coastal areas of California are highly prized winegrape growing regions due to their proximity to the cooling influence of the Pacific Ocean and a wide diversity of soils and topography. This long stretch of land is ideal for the cultivation of classic wine grape varieties and the production of world-class wines.
