Bon Coeur produces Cabernet Sauvignon from Napa Valley, the North Coast region renowned for structured, age-worthy reds. The winery's portfolio centers on this single varietal, with three expressions: the Reserve Cabernet Sauvignon and standard Cabernet Sauvignon both rated 90 by Wine Enthusiast, and the Cuvée Marilyn Cabernet Sauvignon at 88. Napa Valley's volcanic soils and diurnal temperature swings create ideal conditions for Cabernet, yielding wines with ripe fruit, tannin definition, and the potential for extended cellaring. Bon Coeur's focused approach—multiple iterations of the same grape from the same appellation—reflects a commitment to exploring terroir nuance and vintage variation within a single varietal framework.
