Source-derived summary

Tenuta San Guido is an Italian wine producer in the DOC Bolgheri in Toscana, known as a producer of "Super Tuscan" wine. It produces Sassicaia, a Bordeaux-style red wine. The estate also produces a second wine, Guidalberto, and a third wine, Le Difese. Tenuta San Guido is member of the Primum Familiae Vini.

History

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) originated in 1948 when first produced by Incisa della Rocchetta using Cabernet Sauvignon vines and for years only used for family consumption. A story about these vines being sourced from Château Lafite-Rothschild was dismissed by Mario's son, Nicolò Incisa della Rocchetta, as the vineyard was planted from "cuttings from 50-year-old vines from a friend's estate near Pisa".

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. Initially, there were only a few thousand bottles available, but those created a demand for more. Mario Incisa della Rocchetta hired consulting enologist Giacomo Tachis to further refine the wine while increasing production.

Editorial analysis

Why this record matters

The phrase “italian controlled designation of origin wine from Tuscany” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

Critical limits

A concise general-reference account can conceal disagreements about scope, terminology or the weight assigned to individual sources. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
