The Central Coast AVA is a large American Viticultural Area in the U.S. state of California that spans from Santa Barbara County in the south to the San Francisco Bay Area in the north. The boundaries of the Central Coast include portions of six counties. With around 100,000 acres (400 km2) planted to wine grapes, Chardonnay accounts for more than half of the total. Within this larger AVA are several smaller appellations that share the same cooling influence from the Pacific Ocean.
