About Columbia Valley
Columbia Valley is the largest of Washington State's wine growing regions, with almost 11 million acres. It encompasses a number of smaller regions, including Yakima Valley, Walla Walla Valley, Red Mountain and more. The vast area consists of a range of climates, allowing viticulturists to plant a diverse selection of grape varieties. Most wineries plant rows sparsely, which helps the vines survive the harsh winters.
Notable FactsMerlot is the most popular and most planted grape of the area, followed by Cabernet Sauvignon and Chardonnay. Syrah and Riesling are also popular and continue to grow in acreage.
The most famous of the California wine regions is Napa Valley, and these wines are certainly outstanding – but it's not as broad and diverse as its larger neighbor, Sonoma County. Down south, Santa Barbara's Santa Maria Valley is well-known for its Rhône blends, as well as cool-climate varieties like Pinot and Chardonnay. The Central Coast, the largest California AVA, has many different microclimates that lead to a wide range of wines with many sub-AVAs.
