Establishment of the Columbia Hills Viticultural Area

The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes the 29,387-acre "Columbia Hills" American viticultural area (AVA) in Klickitat County, Washington. The newly established AVA is located entirely within the existing Columbia Valley 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.
