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.
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.
