Washington ranks second in the United States in the production of wine, behind only California. The Yakima Valley AVA was established in 1983 in the state's oldest agricultural region. It is Washington's third largest officially designated American Viticultural Area (AVA), and is responsible for more than 40% of the state's entire wine production. Located within the larger Columbia Valley AVA, the Yakima Valley AVA is sub-divided into the three smaller wine regions, each with its own distinctive growing conditions. They are known as Red Mountain AVA, Snipes Mountain AVA, and Rattlesnake Hills AVA. Of the viticultural region's 665,000 acres (269,000 ha), nearly 11,120 acres (4,500 ha) were planted in 2008.
