Philip Togni produces wines in St. Helena, a region renowned for structured Cabernet Sauvignon and age-worthy reds. The winery's portfolio centers on Cabernet Sauvignon in two expressions: the core bottling and Tanbark Hill, both drawing on the varietal's capacity for depth and complexity in Napa Valley's volcanic soils. A distinctive sweet red, Ca' Togni, blends Muscat Blanc and Muscat Hamburg—a departure that showcases aromatic potential alongside the house's primary focus on Cabernet. Decanter, Wine Advocate, Wine Enthusiast, and Wine Spectator have all assessed the winery's releases, reflecting its standing among serious collectors and critics.
