California's northernmost and most distinctive cool-climate wine region in Mendocino County, where the Anderson Valley's deep canyon channels Pacific fog and cool air from the coast. Famous for Pinot Noir, Gewürztraminer, and Alsatian varieties that thrive in conditions utterly unlike the rest of California. Also the source of premium sparkling wine base wines for Roederer Estate.
