Schrader produces Cabernet Sauvignon from Calistoga's most coveted vineyard sites. The winery's portfolio centers on fruit from Beckstoffer To Kalon and Beckstoffer Las Piedras—two of Napa Valley's benchmark terroirs. The CCS and Old Sparky bottlings from To Kalon represent the house's core expression, while the Colesworthy from Las Piedras offers a distinct mineral and structural profile. These wines have been assessed by Decanter, Wine Enthusiast, Wine Advocate, and Wine Spectator. Calistoga's warm days and volcanic soils yield Cabernet with density and power, characteristics evident across Schrader's lineup. The winery's focus on single-vineyard, varietal-driven Cabernet reflects a commitment to terroir specificity rather than breadth.
