There are more than 427,000 acres of grape vines planted in California, covering over 700 miles from Riverside County to Mendocino County. The wine regions in California are divided into four different regions. California would be the fourth largest wine producer on the planet if it were a country.

The 107 American Viticulture Areas include the Sonoma Valley Napa, Rutherford, Russian River Valley, and  AVAs. California’s Central Valley is the largest wine region and stretches for more than 300 miles from the northern Sacramento Valley to the southern San Joaquin Valley. Almost 75% of all California wine grapes are produced here including California's bulk, box and jug wine producers like Franzia, Gallo, and the Bronco Wine Company.

California is divided into four regions that include the North Coast, Central Coast, South Coast, and the Central Valley. The North Coast includes Sonoma County, Napa Valley, Mendocino, and Lake County. The Central Coast covers the Santa Clara Valley, San Lucas, Santa Cruz Mountains, Paso Robles, San Lucas, The Santa Ynez Valley, Livermore Valley, and Santa Barbara County. The South Coast includes Temecula Valley, Leona/Antelope Valley, Ramona Valley, and San Pasqual Valley. California’s Central Valley includes the Sierra Foothills and the most notable being Lodi.
