The famed Napa County wine region is located above San Franciso in the northern California coastal region and is served by San Francisco and Oakland International Airports. Some of the very best Chardonnays, Cabernets and Merlots are made in the Napa Valley.

Established in 1981, the Napa Valley AVA (American Viticultural Area) covers 225,300 acres of land, encompassing almost the entire county of Napa and is home to 391 brick and mortar wineries. Within that area, there are 44,000 acres of vineyards planted. Cabernet Sauvignon is king in Napa Valley with a total of 17,300 acres, and Chardonnay is the most widely planted white wine variety with 7,600 acres. Napa crushed about 120,000 tons in 2004 or four percent of the wine tonnage for California.
