Wine Region Profile: The Columbia Valley American Viticultural Area

The Columbia Valley AVA is a wine region located across over 11 million acres across Washington, Oregon, and Idaho; however, the majority of the region's vineyards are in the south-eastern corner of Washington State. Some criticism exists that the Columbia Valley AVA is so large that it is almost meaningless in terms of expressing a terroir. It covers vast area with a wide range of climates, soils, and topography. 

The sheer size of the Columbia Valley AVA may make it difficult to establish a consistent sense of terroir across the region. Some say the AVA designation is more of a marketing tool than an accurate expression of a specific terroir, as it allows winemakers to label their wines with a recognizable appellation. 

Proponents of the Columbia Valley AVA, however, argue that despite its size, the region shares common characteristics that can be expressed in the wines produced there, which say “Washington Wine”. These include the arid, continental climate, well-drained soils, and the influence of the Columbia River, which can all contribute to the distinctiveness of the wines. 

Additionally, when you check out wines from the best wine store USA, you’ll notice the nested AVAs within the Columbia Valley AVA, such as the Yakima Valley AVA and the Walla Walla Valley AVA, can provide a more specific sense of terroir within the larger region. By designating smaller, more defined areas within the Columbia Valley AVA, winemakers can highlight the unique characteristics of the grapes grown and the wines produced in those areas.
