With nearly three-quarters the size of France, California accounts for nearly 90 percent of entire American wine production. The Californian wines entered the international stage at the 1976 Judgment of Paris wine competition when Californian wines beat out French wines in both red and white wine categories.
California has over 107 American Viticultural Areas (AVAs), including the well known Napa, Russian River Valley, Rutherford and Sonoma Valley AVAs and about 1200 wineries of which 400 are located north of San Francisco also known as the Wine Country. Therefore, you can find a lot of wine shops around San Francisco. One of those shops is called “Cellar 360” and is located at Ghirardelli Square, which also hosts an annual wine festival called “unCORKED!” in May.
