South Coast AVA
The South Coast AVA is an American Viticultural Area in the state of California that encompasses grape-growing regions in five counties of Southern California: Los Angeles, Orange, Riverside, San Bernardino, and San Diego. This large appellation includes a number of smaller sub-appellations that all share the common ecology trait of having warm weather moderated by cooling coastal influences from the Pacific Ocean.
