The area of south-central Washington occupied by Benton County has been known primarily as an agricultural hub since its settlement by white Americans. The rise of viticulture has had a profound impact on the agricultural and tourism industries over the past two decades, and has in many ways reshaped the reputation of the region. The Yakima Valley AVA, part of which is located in Benton County, was the first American Viticultural Area established within Washington State, gaining the recognition in 1983. As the Washington wine industry began to focus more on terroir, three sub-appellations have been created for areas within the Yakima Valley AVA that demonstrate unique microclimates and soil conditions which crafted different wines from their neighboring areas. The Red Mountain AVA, which lies in its entirety on Benton County, was created in 2001. The county also includes part of the Horse Heaven Hills AVA which is part of the larger Columbia Valley AVA.
