Encompassing more than a third of the state, the Columbia Valley is by far Washington’s largest growing region at over 11 million acres. The appellation is located in central, south-central, and south-eastern Washington with part of the appellation spilling across the border into Oregon.

The Columbia Valley is home to over 99% of all of Washington’s vinifera acreage. Cabernet Sauvignon is the most planted grape followed by Merlot, Chardonnay, Riesling, and Syrah. However, over 30 vinifera varieties are currently planted in this region.
