Tenuta San Guido

Tenuta San Guido was established by marchese Mario Incisa della Rocchetta, who was also co-owner of the race horse Ribot.

Considered the seminal "Super Tuscan", the name Sassicaia (Italian sasso meaning "stone", indicating a stony field)[1] originated in 1948 when first produced by Incisa della Rocchetta using Cabernet Sauvignon vines and for years only used for family consumption.

[4] Though for years Sassicaia remained the marchese's personal wine, his son Nicolò and nephew Piero Antinori convinced him to release it commercially, starting with the 1968 vintage, which was unveiled in 1971.

[4] At a 1978 Decanter tasting of "great clarets", a panel including Hugh Johnson, Serena Sutcliffe and Clive Coates awarded the 1972 Sassicaia first place over a field of 33 wines from 11 countries.

[citation needed] The most recently added wine, Le Difese,[8] is composed of 70% Cabernet Sauvignon and 30% Sangiovese, with an annual production of 120,000 bottles.
