Dunn produces Cabernet Sauvignon from Napa Valley, with particular focus on fruit from Howell Mountain and the Trailer Vineyard. The winery's core expression—a Napa Valley Cabernet Sauvignon—sits alongside single-vineyard bottlings that reflect the distinct terroir of their sources. Howell Mountain, the volcanic bench east of the valley floor, yields structured wines with the mountain's characteristic density and aging potential. The Trailer Vineyard Cabernet Sauvignon represents the pinnacle of the range. These wines have been assessed by major critics including Decanter, Wine Advocate, Wine Enthusiast, Wine Spectator, and Falstaff, reflecting their place within serious Napa Cabernet discourse.
