Heitz Cellar produces Cabernet Sauvignon from St. Helena, drawing on vineyard-designated fruit to craft wines of depth and structure. The winery's portfolio centers on three flagship expressions: Bella Oaks Vineyard Cabernet Sauvignon, Martha's Vineyard Cabernet Sauvignon, and Trailside Vineyard Cabernet Sauvignon. Each represents a distinct terroir within the region, with the wines earning recognition from Decanter, Wine Enthusiast, Wine Advocate, and Wine Spectator. St. Helena's warm days and cooling evening breezes create conditions suited to Cabernet Sauvignon's ripening needs, yielding wines with the varietal's characteristic structure and aging potential. The vineyard-specific approach allows the winery to express subtle differences in soil, aspect, and microclimate across its sources.
