Tentuta San Guido produces Sassicaia – Italy’s most famous wine. An icon from the Bolgheri coastline of Tuscany, made from Cabernet Sauvignon and Cabernet Franc, its rise to prominence in the late 1970s sparked the Super Tuscan revolution. Started in 1948 by Marchese Mario Incisa della Rocchetta, the wines were not commercially available until the 1968 vintage. So important are their wines, in 1994 the Sassicaia site was declared an official subzone of the Bolgheri DOC and established as a separate DOC (Bolgheri Sassicaia) in 2013.
