West Sonoma Coast is an American Viticultural Area (AVA) located in portions of Sonoma County, California. It was established as the state’s 144th and Sonoma County's 19th viticultural area on May 22, 2022 by the Alcohol and Tobacco Tax and Trade Bureau (TTB), Treasury after reviewing the petition submitted by Patrick L. Shabram, on behalf of the West Sonoma Coast Vintners Association, proposing a viticultural area named "West Sonoma Coast." The AVA encompasses 141,846 acres (222 sq mi) with approximately 47 commercial vineyards cultivating about 1,028 acres (416 ha) throughout an area largely located within the Marine zone climate classification including the established Fort Ross-Seaview viticultural area.
