Tenuta San Guido produces wines in Toscana, central Italy, drawing on the region's tradition of blending international and native varieties. The winery's flagship Sassicaia combines Cabernet Franc and Cabernet Sauvignon into a structured red that has attracted the attention of Wine Spectator, Wine Advocate, Decanter, Wine Enthusiast, and Falstaff. Guidalberto, a Cabernet Sauvignon and Merlot blend, represents a secondary expression of the estate's approach to Bordeaux varieties in a Tuscan context. Le Difese, which marries Sangiovese with Cabernet Sauvignon, bridges local and international grapes. These wines reflect the character of their region: Toscana's capacity for aging reds with both power and refinement, built on volcanic and mineral soils that lend complexity to the fruit.
