Sonoma County wine refers to the viticulture and winemaking in Sonoma County, California, United States.
County names in the United States automatically qualify as legal appellations of origin for wine produced from grapes grown in that county and do not require registration with the Alcohol and Tobacco Tax and Trade Bureau (TTB) of the Treasury Department. TTB was created in January 2003, when the Bureau of Alcohol, Tobacco and Firearms, or ATF, was extensively reorganized under the provisions of the Homeland Security Act of 2002.
Sonoma County is one of California's largest producers of wine grapes, far outproducing the Napa Valley AVA.
