Three Rivers sources grapes from many different areas within the greater Columbia Valley, including high-quality vineyards in the Walla Walla Valley and Red Mountain AVA. We continue to source grapes from a wide array of vineyards in several diverse geographic zones to deliver the highest quality wines. The interior of our winery is divided into two distinct areas. There is a 14,000 sq. ft. cellar and barrel room that is used for the production and storage of fine wines, and a 4,000 sq. ft. area that includes a Tasting Room and private meeting room.
