The South Coast AVA, established in 1985, spans Los Angeles, Orange, Riverside, San Bernardino, and San Diego counties, offering a diverse range of microclimates from coastal cool to inland warmth. Influenced by the Pacific Ocean, it supports cool-climate grapes like Chardonnay and Pinot Noir, as well as warm-climate varieties such as Cabernet Sauvignon, Syrah, and Zinfandel. Key sub-AVAs include Temecula Valley, Malibu Coast, and Ramona Valley, with over 200 wineries producing award-winning wines. Known for innovative winemaking and sustainable practices, the South Coast AVA continues to gain recognition as a premier Southern California wine region.
