Conn Creek produces Cabernet Sauvignon in St. Helena, the heart of Napa Valley's most prestigious growing region. The winery's portfolio centers on this noble varietal, with particular focus on single-vineyard expressions like the Truchard Vineyard Cabernet Sauvignon. St. Helena's volcanic soils and diurnal temperature swings favor Cabernet's ripening, yielding wines with structure and depth. Conn Creek's Cabernet Sauvignons have been assessed by Wine Enthusiast, Wine Advocate, and Decanter, earning ratings in the low-to-mid 90s. The winery's approach emphasizes the character that terroir and varietal selection bring to the glass—Cabernet's characteristic dark fruit, tannin architecture, and aging potential expressed through St. Helena's distinctive lens.
