Alpha Omega produces Cabernet Sauvignon from St. Helena's most distinguished vineyard sites. The Tench Vineyard Cabernet Sauvignon, Beckstoffer Dr. Crane Vineyard Cabernet Sauvignon, and Caspar Vineyard Cabernet Sauvignon represent the winery's focus on single-vineyard expression within Napa Valley's premier growing region. Each wine draws from the specific terroir of its source, capturing the structure and depth that St. Helena's volcanic soils and diurnal temperature swings impart to Cabernet. The winery's selections have been assessed by Decanter, Wine Enthusiast, Wine Advocate, Falstaff, and Wine Spectator, reflecting serious engagement with the region's benchmark varietal.
