Tenuta San Guido is much better known by the name of its most famous wine – Sassicaia. An Italian producer located in the Tuscan region of Maremma, it has its own single-estate DOC appellation granted to its flagship label: Bolgheri Sassicaia DOC.

Sassicaia is one of Italy's most iconic wines. Touted as the original Super Tuscan wines, this wine was granted an eponymous appellation name and this says a lot about the vineyard supremacy and its superlative wine quality. The wine is typically a Cabernet Sauvignon and Cabernet Franc blend of Tuscany's coastal area of Bolgheri vines. It delivers aromas and flavours of red and black currants, cedar and tobacco, suave tannins and great length.

The estate also produces a second wine, Guidalberto; and a third wine, Le Difese.
