Keenan produces Cabernet Sauvignon and Bordeaux blends from St. Helena, a region defined by mountain terrain, volcanic soils, and the intensity that comes with elevation. The Reserve Cabernet Sauvignon stands as the winery's flagship, built on the varietal's natural structure and depth. Mernet Reserve and Capstone—both blends of Merlot and Cabernet Sauvignon—demonstrate the winery's approach to balancing power with complexity. Decanter, Wine Advocate, Wine Enthusiast, and Wine Spectator have all assessed Keenan's portfolio, with the Reserve Cabernet earning particular recognition among prestige critics.
