Dumas Station produces wines from Columbia Valley, Washington's premier red wine region. The winery focuses on Cabernet Sauvignon and Bordeaux blends, drawing on the region's warm days and cool nights to develop structure and depth. The Minnick Hills Reserve Cabernet Sauvignon and Reserve Cabernet Sauvignon showcase the varietal's dark fruit and tannin architecture, while Cuvée No. 439—a blend of Merlot, Cabernet Franc, and Cabernet Sauvignon—demonstrates the winery's approach to layered, complex reds. These wines have been assessed by Wine Enthusiast, Wine Advocate, Decanter, Wine Spectator, and Falstaff.
