California, United States

Sonoma County is one of California's largest producers of wines, far outproducing the Napa Valley. Now there are over 250 wineries in the county, and over half are less than 20 years old. Alexander Valley makes up a large section of Sonoma County, and to date is a proven area for Chardonnay, Cabernet Sauvignon and Zinfandel, and more recently, Merlot. There is also Carneros, a vineyard section at the southern tips of the Napa and Sonoma County line with especially cool climate that has been specifically suited for Pinot Noir and Chardonnay.
