California put the US on the map for producing quality wines. Most of the state's wine regions are found between the Pacific coast and the Central Valley. The Pacific Ocean and large bays, like San Francisco Bay, serve as tempering influences to the wine regions nearby providing cool winds and fog that balance the heat and sunshine.

California has over 427,000 acres planted under vines mostly located in a stretch of land covering over 700 miles from Mendocino County to the southwestern tip of Riverside County. There are over 107 American Viticultural Areas (AVAs), including the well known Napa, Russian River Valley, Rutherford and Sonoma Valley AVAs. Over a hundred grape varieties are grown in California including French, Italian and Spanish wine varietals as well as hybrid grapes. The most important grapes of California are: Cabernet Sauvignon, Chardonnay, Merlot, Pinot Noir, Sauvignon Blanc, Syrah, and Zinfandel.
