Duckhorn produces Cabernet Sauvignon and Bordeaux blends from St. Helena, a region defined by volcanic soils and the tempering influence of the San Pablo Bay. The Cork Tree Vineyard Cabernet, a single-varietal expression of Cabernet Sauvignon, demonstrates the precision achievable in this terroir. The Howell Mountain Red—a blend of Petit Verdot, Merlot, Cabernet Franc, and Cabernet Sauvignon—captures the structure and depth characteristic of mountain fruit. The Discussion, a Cabernet Franc–led blend with Cabernet Sauvignon and Merlot, rounds the portfolio with a different aromatic profile. These wines have been assessed by Decanter, Wine Enthusiast, Wine Advocate, Wine Spectator, and Falstaff.
