Columbia Gorge is an American Viticultural Area (AVA) which includes land surrounding the Columbia River Gorge, straddling the border between Oregon and Washington. The AVA was established by the Alcohol and Tobacco Tax and Trade Bureau {TTB), Treasury on July 9, 2004 after reviewing the petition submitted by Mark Wharry, on behalf of the Columbia River Gorge Wine Growers Association, proposing the viticultural area named "Columbia Gorge." The 280 square miles (179,200 acres) AVA is located about 60 miles (97 km) east of Portland, Oregon, straddles the Columbia River for 15 miles (24 km), and extends into south-central Washington and north-central Oregon. The area surrounds Hood River, Oregon, and White Salmon, Washington, and is generally bordered by B Z Corner, Washington, on the north; Lyle, Washington, on the east; Parkdale, Oregon, on the south; and Vinzenz Lausmann State Park, Oregon, on the west. The area is just west of the established Columbia Valley viticultural area and shares a border with it. Due to the significant gradations of climate and geography found in the gorge, this AVA exhibits a wide range of terroir in a relatively small region; it is marketed as a "world of wine in 40 miles".

Description

The Columbia Gorge AVA consists of four counties; Hood River and Wasco counties in Oregon, and Skamania and Klickitat counties in Washington. The region stretches from Hood River, Oregon and Underwood, Washington in the west, to Rowena, Oregon and Lyle, Washington in the east. It includes the river valleys of the Hood River and Deschutes River in Oregon, and the Klickitat River and White Salmon River in Washington.

The Columbia River (shown here in Hood River County, Oregon) is at the heart of the Columbia Gorge AVA

As this region lies to the east of the summits of nearby Mount Hood and Mount Adams, it is in rain shadow of these Cascade volcanoes. The region is significantly drier than the Portland metropolitan area to the west. Annual precipitation ranges from 30 in (762 mm) at the western end of the range, to only 18 in (457 mm) in the eastern part. Elevation in the region varies considerably, increasing as one travels from the Columbia River into the plateaus on either side, and the strong Columbia Gorge winds also play a factor in the region's climate. This allows a wide variety of grapes to be grown in the Columbia Gorge.

The region has nearly 40 vineyards, growing a wide variety of grapes, including Syrah, Pinot noir, Chardonnay, Gewürztraminer, Zinfandel, Cabernet Sauvignon, Pinot gris, Riesling, and Sangiovese.
