The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes the approximately 690-square mile "Upper Hiwassee Highlands" viticultural area in Cherokee and Clay Counties, North Carolina, and Towns, Union, and Fannin Counties, Georgia. The viticultural area does not lie within or contain 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.
