In the 1920s the Marchese Mario Incisa della Rocchetta dreamt of creating a ‘thoroughbred’ wine and for him, as for all the aristocracy of the time, the ideal was Bordeaux. In the 1940s, having settled with his wife Clarice on the Tenuta San Guido on the Tyrrhenian coast, he experimented with several French grape varieties. A wine made mainly from Cabernet Sauvignon was a fundamental change to the Tuscan and Piedmont tradition of Sangiovese and Nebbiolo, respectively. The innovative decision to plant this variety at Tenuta San Guido was partly due to the similarity Mario Incisa had noted between Tuscan terrain and that of Graves in Bordeaux. The Marchese's first vintages were not warmly received. Critics accustomed to light, local wines were not encouraging; it was not taken into consideration that wines made from the more complex Cabernet Sauvignon grape would need more time to mature and develop. And thus from 1948 to 1967, Sassicaia remained a strictly private affair, only to be consumed at Tenuta San Guido. Friends and relatives now urged Mario Incisa to experiment further with his project and perfect his revolutionary winemaking style. It was not until 1968 that Sassicaia was first commercially released – the welcome was worthy of a Bordeaux Premier Cru.
