The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes the approximately 215-square mile "Crest of the Blue Ridge Henderson County" viticultural area in Henderson County, North Carolina. The Crest of the Blue Ridge Henderson County viticultural area is not located within any other established viticultural area. TTB designates viticultural areas to allow vintners to better describe the origin of their wines and to allow consumers to better identify wines they may purchase.
