San Sano produces wines from Toscana in central Italy, drawing on the region's Sangiovese tradition and the structure of Canaiolo Nero. The winery's Guarnellotto Chianti Classico Riserva—a blend of Canaiolo Nero and Sangiovese—represents the core of its portfolio, rated by Wine Spectator, Wine Enthusiast, and Wine Advocate. The standard Chianti Classico follows a similar varietal foundation, while Borro Al Fumo Rosso introduces Cabernet Sauvignon alongside Sangiovese, reflecting the broader Tuscan practice of blending international and indigenous grapes. These wines span the range of Tuscan red expression, from the austere elegance of Chianti Classico to the richer complexity of the riserva designation.
