Retro Cellars produces Petite Sirah from Napa Valley, the North Coast region of California known for structured red wines and volcanic soils. The winery's focus centers on this dark-skinned variety, which thrives in the valley's warm days and cool nights. Los Abuelos Vineyard Petite Sirah and Park Muscatine Vineyard Petite Sirah represent the winery's core offerings, both drawing critical attention from Decanter, Wine Advocate, Wine Enthusiast, Wine Spectator, and Falstaff. Petite Sirah as a varietal demands patience—the grape yields wines with dense tannins, deep color, and aging potential. Napa Valley's reputation for precision viticulture and winemaking infrastructure supports the kind of extraction and balance these wines require. Retro Cellars' selection emphasizes single-vineyard expressions alongside a broader Petite Sirah bottling, allowing exploration of how site and vintage shape the variety's character across the valley floor.
