What is Tenuta San Guido?
The modern chapter began in the 1940s, when Marchese Mario Incisa della Rocchetta established Cabernet Sauvignon and Cabernet Franc on stony, well-drained sites. The first commercial Sassicaia was 1968, released in 1971 and initially sold as table wine; its success contributed to later regulatory changes. Today the estate produces three labels: Sassicaia, Guidalberto, and Le Difese.
