Sassoferrato produces wines in Mendocino County, part of California's North Coast region. The winery's portfolio centers on Italian and Bordeaux varieties, with Monte de Ferro—a blend of Cabernet Franc, Sangiovese, and Cabernet Sauvignon—as its flagship. A pure Sangiovese and Vermentino round out the core range. Wine Advocate and Wine Enthusiast have rated these releases, with Monte de Ferro achieving particular recognition among the three. The winery's focus on Sangiovese and Vermentino reflects a deliberate turn toward Mediterranean varieties suited to Mendocino's diverse microclimates, while the Bordeaux-Italian blend demonstrates an approach to structure and balance across Old World traditions.
