The Alcohol and Tobacco Tax and Trade Bureau (TTB) establishes the approximately 16,870-acre "The Burn of Columbia Valley" viticultural area in Klickitat County, Washington. The newly- established The Burn of Columbia Valley viticultural area 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.
