Sonoma Coast AVA

The Sonoma Coast AVA is an American Viticultural Area in Sonoma County, California, United States containing more than 500000 acre, mostly along the coastline of the Pacific Ocean. It extends from San Pablo Bay to the border with Mendocino County. The appellation is known for its cool climate and high rainfall relative to other parts of Sonoma County. The area has such a broad range of microclimates that petitions have been made to the United States Department of the Treasury Alcohol and Tobacco Tax and Trade Bureau for the creation of sub-AVAs such as the Fort Ross-Seaview AVA which was approved in December 2011.
