Brunello "Il Greppo" is the father of the whole denomination because it is the one who gave birth to the production of Brunello di Montalcino. Until 1825 the most produced wine in Montalcino was Moscadello, a slightly sweet and easy to drink white wine. Clemente Santi instead began to study the characteristics of Sangiovese Grosso, called Brunello for the dark color of its coat. In 1860 Ferruccio, Clemente's nephew, started producing a red wine made of Brunello and decided to let it rest in the cellar. So he vinified in purity the Sangiovese Grosso that he cultivated in his estate "Il Greppo" and he waited until it was perfectly mature. The day of the tasting remained in history because the first and historical Brunello was born, whose roots have always been linked to Biondi Santi.
