Proposed Establishment of the Mill Creek-Walla Walla Valley Viticultural Area

The Alcohol and Tobacco Tax and Trade Bureau (TTB) proposes to establish the approximately 4,898-acre "Mill Creek--Walla Walla Valley" American viticultural area (AVA) in Walla Walla County, Washington. The proposed viticultural area lies entirely within the established Columbia Valley and Walla Walla Valley AVAs. 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. TTB invites comments on this proposed addition to its regulations.
