California
California is one of the most important regions in the United States for wine production. Thanks to the temperate climate and particularly suitable soils, it has become one of the most highly rated areas in the New World. The most famous production areas in California are Sonoma, Napa Valley, Mendocino and Santa Barbara. Red and white wines are produced with the most important traditional grapes and with zinfandel, a grape that corresponds to our primitivo.
