Washington Wine Region

The Cascade Mountain range slices Washington into two distinct climate zones. In the west, the land is hilly and evergreen, embracing the waters and islands of Puget Sound. In the east, the Columbia Valley-which comprises one-third of Washington State's land mass and produces 98 percent of its wine grapes-is protected from rainfall.

Washington has five major viticultural appellations, as designated by the U.S. government. The appellations define specific geographic regions. Three of them, Red Mountain, Yakima Valley and Walla Walla Valley, are located within the larger Columbia Valley appellation. The Puget Sound appellation is the only officially recognized grape-growing area located in Western Washington..
