The?Central Coast?AVA?in California covers the long stretch of coastline from San Francisco Bay south to Santa Barbara, and reaches inland from the Pacific Ocean to the borders of the?Central Valley. The climate and topography vary enormously across this immense region, making it impossible to generalize about winegrowing conditions.?Chardonnay?and?Pinot Noir?are the most important grapes planted in the region, but?Cabernet Sauvignon,?Zinfandel?and?Sauvignon Blanc?make up a sizable chunk of the wines produced here.
