The "Sassicaia" of the historic "Tenuta San Guido" of Bolgheri in the province of Livorno was obtained from Cabernet Sauvignon (85%) and Cabernet Franc (15%) grapes.
The vineyards of origin insist on limestone soils rich in marl, stones and stones (which give the wine its name) and partly clayey, located at an altitude between 100 and 300 meters above sea level. Fermentation was carried out in stainless steel at a controlled temperature between 28 ° and 30 ° C without adding external yeasts. After malolactic fermentation, the wine was transferred to French oak barriques (for 1/3 new wood and for the remainder of the first and second passage) where it was aged for 24 months, keeping the masses separated by vineyard origin. The assembly was in fact carried out only close to bottling. Before being put on the market, each Sassicaia rested for some time in the bottle. A sensational wine, a true champion of world enology!
