Location:
The Columbia Valley AVA is a very large growing region with 11 million acres of land in total. Most of Columbia Valley and its six sub-appellations lie in Washington State, with a small section in Oregon stretching from The Dalles to Milton-Freewater. The region is 185 miles wide and 200 miles long.
The Numbers:
50 wineries, 29,000 vineyard acres
Wine History:
On the Oregon side, the Columbia Valley wine history dates back to the early 1900s, when settlers planted the area's first vineyard on a steep, southward-sloping hill near the small town of The Dalles. These Zinfandel vines, which are now more than 100 years old, still produce wine grapes at what is today known as The Pines 1852 Vineyard, whose vintner revitalized the land in the early 1980s. Around the same time, as the Washington side of the Columbia Valley appellation began to flourish with large-scale wineries, reputable winemakers started tagging the small Oregon side as an excellent location for high-quality wine grapes. The appellation became official in 1984.
Climate:
The Columbia Valley has a largely Continental High Desert Climate. The hot days promote slow, even ripening, while the cool nights ensure that grapes retain their natural acidity. The area receives just 6 to 8 inches of annual rainfall, making supplemental irrigation a necessity throughout the region.
Soils:
About 15,000 years ago a series of tremendous ice age floods (dubbed the Missoula Floods) deposited silt and sand over the area. These deposited sediments, along with wind-blown loess sediment, make up the area's present-day soils, which are well drained and ideal for grapevines.
Topography:
This is a huge area covering 11 million acres. Mostly, the Columbia Valley lies on the Columbia River Plateau and encompasses the valleys formed by the Columbia River and its tributaries, including the Walla Walla, Snake and Yakima rivers. Mountain ranges border the Columbia Valley region on the west and north, while the Columbia River acts roughly as a boundary to the south, and the Snake River near Idaho acts as the border to the east.
Predominant Varieties:
Merlot, Cabernet Sauvignon, Chardonnay, Sauvignon blanc, Riesling, Gewurztraminer, Semillon, Pinot gris, Chenin blanc, Syrah
While you're here:
The Columbia Valley appellation dips across the Columbia River from Washington and into the eastern part of the Gorge near the town of The Dalles, Oregon, which overlooks the river and provides ideal conditions for windsurfing and kite boarding, as well as excellent walleye and sturgeon fishing. Come spring, the area's 6,000 acres of sweet cherry trees come into full blossom, a beautiful sight to see. Culturally, the area is home to the Columbia Gorge Discovery Center and Wasco County Historical Museum, where visitors can learn about the area's natural, Native American and pioneer history, including Lewis and Clark and The Oregon Trail. Also nearby is the charming river front town of Hood River and, of course, the majestic Mt. Hood, which is home to four ski resorts and offers North America's longest ski season and biggest night-skiing area. It's a great place to learn to ski or snowboard, or to go sledding or snowshoeing at one of the many sno-parks.
