California is the largest and most important wine region in the USA. It accounts for the southern two-thirds (850 miles or 1370 kilometers) of the country’s west coast. (Oregon and Washington make up the rest.) The state also spans almost ten degrees of latitude. With mountains, valleys, plains and plateaux, California’s topography is as complex as its climate, offering winegrowers a bewildering choice of terroir.
Californian wines only rose to global renown in the past few decades (notably after the Paris Judgment of 1976). However the state’s viticultural history dates back more than 200 years. European vines were first planted here in the 18th Century, as settlers and missionaries made their way up and down the west coast. They brought with them the Mission grape – the vinifera variety also instrumental in establishing viniculture in Central and South America. Although very few Mission vines are to be found in California today, it remains a cornerstone of Californian wine.
