Kontos Cellars draws from the Walla Walla Valley, a distinguished corner of Washington's Columbia Valley known for structured red wines. The winery works with Bordeaux and Rhône varieties—Merlot, Cabernet Sauvignon, Malbec, and Syrah—crafting blends that reflect the region's volcanic soils and continental climate. Brielle, a Merlot-Malbec-Cabernet blend, stands as the flagship. The Boss layers Merlot, Cabernet, Malbec, and Syrah into a more complex frame. Dorsey Seven Hills Vineyard, sourced from a single site, combines Cabernet Sauvignon, Malbec, Petit Verdot, and Merlot. These wines have been assessed by Wine Advocate, Wine Enthusiast, Wine Spectator, Decanter, and Falstaff.
