Caterwaul produces Cabernet Sauvignon from Stags Leap District, a region defined by volcanic soils, morning fog, and afternoon sun that shape wines of structure and depth. The winery's portfolio centers on single-vineyard expressions: Cemetery Vineyard and Regusci Vineyard Cabernet Sauvignons, alongside a core Cabernet Sauvignon blend. Wine Advocate and Wine Enthusiast have rated these releases, with the Cemetery Vineyard bottling reaching 96 points. The Regusci Vineyard follows at 95 points. These scores reflect the precision required to balance Stags Leap's ripe fruit with the tannin architecture the district's terroir demands. Caterwaul's focus on Cabernet Sauvignon—the varietal that defines the region—positions the winery within Napa's most celebrated benchmarks for the grape.
