Vineyards in California stretch as far south as San Diego and as far north as the Oregon border. The total winegrowing area covers more than 700 miles and includes over 100 viticultural regions. These can be divided into five large wine growing regions, Northern California Coast, Central California Coast, Southern California, Sierra Nevada and Central Valley. California’s largest wine producing region is the Napa Valley on the Northern California Coast. The Napa Valley is renowned for its vast range of appellations and wine styles, ranging from rich reds with soft tannins and intense fruit, to spicy Zinfandels and rich creamy Chardonnays. By contrast, San Diego in Southern California is the smallest wine growing region in California however due to its rich soils it produces some very fine Chardonnays, Cabernets and Zinfandels.
