Columbia Valley

Established 1984

Washington’s largest viticultural region, Columbia Valley covers almost 11 million acres and encompasses the Horse Heaven Hills, Rattlesnake Hills, Yakima Valley, Walla Walla Valley, Red Mountain, and Wahluke Slope AVAs within its borders. Over 30,000 vineyard acres, representing a number of meso- and micro-climates are planted on predominately south-facing slopes on sandy loam to silt loam soils. Water from mountain snowpack, delivered to the vineyards via the Yakima and Columbia Rivers, provides ample water for irrigation.
