California
California is the largest and most important wine region in the United States. Occupying the
southern two-thirds of the country's west coast (Oregon and Washington make up the rest), it
spans almost ten degrees of latitude and 850 miles (1370km) of coastline. With mountains,
valleys, plains and plateaux, the state's topography is as complex as its climate, offering
winegrowers a bewildering choice of terroir.
