The Cabernet Sauvignon draws on the region's capacity for structured, age-worthy reds, while the Chardonnay reflects California's tradition of rich, complex whites. Wine Enthusiast has rated both expressions, with the Cabernet Sauvignon earning an 87.5 and the Chardonnay a 87.0. These core offerings represent the winery's approach to varietal-driven winemaking in one of North America's most established wine regions.
