Columbia Valley

  • Established in 1984
  • Washington's largest viticultural region, covering 8,748,949 acres in Washington, represents a full third of Washington State's land mass. Columbia Valley is a cross border AVA, totaling 11,308,636 total acreage.
  • The Columbia Valley contains 99% of wine grapes grown in Washington State, 59,234 acres.
  • Columbia Valley's vast size allows for a number of meso- and micro-climates.
  • Vineyards are planted on predominately south-facing slopes, increasing solar radiation in summer and promoting air drainage in winter.
  • Riesling, Merlot, Chardonnay, Syrah and Cabernet Sauvignon are the most widely planted varietals.
  • Growing season of 180-200 days with annual rainfall averaging 6 to 8 inches (15-20 cm).
  • The Columbia Valley contains the American Viticultural Regions of Red Mountain, Yakima and Walla Walla Valleys, Wahluke Slope, Rattlesnake Hills, Horse Heaven Hills, Snipes Mountain, Lake Chelan, Naches Heights and Ancient Lakes within its borders.
  • With the exception of Lewis-Clark Valley, Puget Sound and Columbia Gorge, all other growing regions in Washington are subappellations of the Columbia Valley.
