Washington wine maps4/7/2023 Even so, many grape growers use wind turbines to get air circulating and prevent their vines from the effects of frost. The Columbia River and its tributaries not only provide water but also help to moderate both summer and winter temperatures. On the plus side, where controlled irrigation is possible, this can make a big difference to yields and the quality of the grapes. Hot days here are followed by cool nights, helping to ensure a long and even growing season in which the grapes obtain full ripeness while retaining vital acidity.Īs Columbia Valley is a dry region, irrigation is often required and this restricts the location of its vineyards. The valley lies in a rain shadow caused by the Cascades, which contributes to its dry continental climate. Volcanic, alluvial and windblown material can be found throughout the valley, and soil textures range from silt to gravel to sand.Ĭolumbia Valley is situated between latitudes 46°N and 47°N, the same as the famed French wine regions of Bordeaux and Burgundy. The diversity of soils in the Columbia Valley is a result of these floods and of the consequent weathering of the landscape. During the last Ice Age, the once-sizeable Lake Missoula in Montana broke through its glacial dams, sending huge volumes of water across eastern Washington and into Oregon's Willamette Valley a number of times, depositing soils and shaping the landscape significantly. The Columbia River flows through the rolling, desert-like landscape of the valley, which was carved out thousands of years ago by glacial floods. The Cascade Mountains run along the region's western border, and the barren Channeled Scablands (which are not suitable for viticulture) lie to the east. The Columbia Valley runs for over 300 miles (500km) from around Fort Spokane on the Columbia River, through its most northern sub-AVA, Lake Chelan, before winding roughly south, through the Ancient Lakes of Columbia Valley and the Wahluke Slope and west along both northern Oregon and southern Washington before ending at the Columbia Gorge AVA, also shared between both Oregon and Washington. The vast AVA also contains most of Washington's smaller regions, including Red Mountain, the Walla Walla Valley and Horse Heaven Hills. The Columbia Valley AVA is centered around the Columbia River and its tributaries: the Walla Walla, Yakima and Snake rivers. The area covers just over 11 million acres (4.5 million hectares), of which 40,000 acres (16,000ha) are under vine. Before wine was planted in Walla Walla, WA the city was famous for sweet onions and apricots the size of your hand.Columbia Valley, in the southeastern corner of Washington State, is one of the United States' largest official wine regions (see AVA). The climate on the eastern side is very different than you might imagine it’s dry and sunny! Very large glacial rivers, including the Columbia River, flow through Washington making it possible to support a large farming industry. Most of Washington’s vineyards are located east of the Cascade Mountains. It also costs less to maintain a cellar in the Puget Sound’s temperate zone. By selling directly to customers, wineries are able to make more money per bottle than if they sold to distributors. The system of large vineyards and small wineries works for winemakers because they are located close to their largest buying market around Seattle. How is this possible? Well, since vineyards didn’t start popping up in Washington until the late 1960’s, transporting grapes a very long way was not only possible, it was also a good idea. What makes Washington State different is that the vineyards are up to 200 miles away from where the wine is made. Washington wine country is unlike any other wine region in the world.
