California is the biggest and most important wine region of the United States. The leading grape varieties are for the white Chardonnay and Colombard and for the red Cabernet Sauvignon, Merlot, Zinfandel and Pinot Noir. California is famous for its full-bodied Cabernet Sauvignon from Napa, its oaky Chardonnays from Sonoma and the powerful Zinfandels from the sub-region of Lodi.
