Proposed Establishment of the Mill Creek-Walla Walla Valley Viticultural Area
Key claim: The Alcohol and Tobacco Tax and Trade Bureau proposes a new roughly 4,900-acre Mill Creek–Walla Walla Valley American viticultural area in Walla Walla County, Washington, so wineries can label wines more specifically by grape origin.
Abstract
(Proposed Rule · Treasury Department, Alcohol and Tobacco Tax and Trade Bureau) 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.
Why this matters
AVA designations affect how wineries market and price wines by tying labels to specific grape-growing regions, which can raise the value of local grapes and give consumers more granular origin information. Nesting a small AVA inside established Washington wine regions is a routine but economically meaningful step for growers in the Mill Creek–Walla Walla Valley area, with limited direct impact on food prices or broader farm policy.
