Which individual is known for innovations such as isolating Sangiovese Grosso?

The individual recognized for innovations such as isolating Sangiovese Grosso is Ferruccio Biondi-Santi. He is a pivotal figure in the history of Italian winemaking, particularly for his contributions to the Brunello di Montalcino style. By isolating Sangiovese Grosso, a specific clone of the Sangiovese grape, Biondi-Santi was able to enhance the quality and complexity of the wines produced in Montalcino. His meticulous viticultural practices and commitment to high-quality production have established Brunello di Montalcino as one of Italy's most esteemed wines.

While others like Giovanni Gaja and Angelo Gaja are influential figures in the Italian wine industry, their contributions focus on different aspects of winemaking and innovations in regions such as Barbaresco and Barolo. Alberto Antonini is known for his work in viticulture and wine production but does not have the same singular association with the isolation of Sangiovese Grosso as Biondi-Santi does.
