Columbia Valley is an American Viticultural Area (AVA) located in the U.S. state of Washington. It covers an large area of over 11 million acres and is part of the larger Columbia Basin. The valley stretches across a significant part of the state, from the Oregon border to the foothills of the Cascade Mountains.
The valley is popularly known for its vast and diverse wine-producing regions, including the Yakima Valley, Walla Walla Valley and the Tri-Cities. The region’s wine industry contributes substantially to the state’s economy. Its hot, dry climate and long growing season make it ideal for growing a variety of grapes including Cabernet Sauvignon, Merlot, Syrah, Riesling and Chardonnay.
The Columbia River, after which the valley is named, plays a significant part in the area's agricultural success. The river helps regulate temperatures, reducing the risk of early and late season frosts, which can be detrimental to the harvest.
Beyond viticulture, the Columbia Valley is also home to a variety of other agricultural ventures including orchards and livestock. It also offers a range of outdoor activities like hiking, biking, golfing, and fishing, making it a popular tourist destination.
