The Walla Walla Valley has captured national fame and international acclaim for its top-shelf wineries, starting with the two oldest: Leonetti Cellar and Woodward Canyon Winery. Since Woodward Canyon launched in 1981, more than 100 wineries now operate in the valley.
The Walla Walla Valley is relatively cool compared with other areas of the Columbia Valley (particularly Red Mountain, the Wahluke Slope and the Horse Heaven Hills), and the region has a relatively small amount of vineyard acreage.
Perhaps surprisingly, more than half of the vines are planted on the Oregon side of the valley. Seven Hills Vineyard, planted in the 1980s, was among the first, and others have followed. Not far away is The Rocks District of Milton-Freewater, the first American Viticultural Area within the Walla Walla Valley (and entirely in Oregon).
Because of the fame of other Oregon wine regions, few think of the Walla Walla Valley in terms of being in Oregon. The Dundee Hills, Eola-Amity Hills, Yamhill-Carlton and the massive Willamette Valley all come to mind while talking about Oregon wine. The Walla Walla Valley is not top of mind, perhaps because most of the acreage on the Oregon side is owned by winery owners on the Washington side.
That is slowly changing, and with Willamette Valley Vineyards recently purchasing land in SeVein (a development that includes Seven Hills (east) Vineyard), the perception could well improve more quickly.
