Realignment of the Boundary of the Walla Walla Valley Viticultural Area and the Eastern Boundary of the Columbia Valley Viticultural Area (99R-141P)

This final rule extends the boundary of the Walla Walla Valley viticultural area. This action is the result of petitions filed by growers and winemakers located within the existing area and in the new area being added. This final rule also extends the boundary of the Columbia Valley viticultural area so that it coincides with the boundary of Walla Walla Valley viticultural area. The establishment of viticultural areas and the subsequent use of viticultural area names as appellations of origin in wine labeling and advertising allow wineries to designate the specific areas where the grapes used to make the wine were grown and enable consumers to better identify the wines they purchase.
