Yakima Valley, located in south-central Washington, is the state’s oldest federally designated grape-growing region, established in 1983. Covering 665,600 acres, it is a sub-appellation of the Columbia Valley and home to nearly one-third of Washington’s planted vineyard acreage. The valley’s diverse landscape features deep silt-loam soils over basalt bedrock, with an average annual precipitation of just 8 inches. Irrigation from the Yakima River and local aquifers supports the region’s vineyards, where top varieties include Chardonnay, Riesling, Merlot, and Cabernet Sauvignon.

This AVA is unique for its climatic contrasts, with cooler areas near the Cascade foothills favoring white grape varieties like Chardonnay and Riesling, while the hotter central basin produces high-quality Merlot, Cabernet Sauvignon, and Syrah. Yakima Valley’s range of growing conditions contributes to Washington’s reputation for producing exceptional wines across a variety of styles.
