Purlieu produces Cabernet Sauvignon from premier Napa Valley vineyard sites. The winery's portfolio centers on single-vineyard expressions: Beckstoffer To Kalon Vineyard, Teucer Vineyard, and Georges III Vineyard Cabernet Sauvignon. Each represents a distinct terroir within the valley's North Coast region, where Cabernet thrives in well-drained soils and moderate maritime influence. The wines have been assessed by Wine Advocate, Decanter, and Wine Enthusiast. Purlieu's focus on vineyard-designated bottlings reflects the specificity of Napa Valley's microclimates and soil composition, allowing the character of each site to emerge through the lens of Cabernet Sauvignon.
