Castello di Monsanto owns some of the best vineyard sites within the appellation and is home to the largest reserves of Chianti Classico in Tuscany. In 1962, Fabrizio Bianchi founded the winery after it was presented to him as a wedding gift from his parents. That same year, pioneering Monsanto was the first winery to make a Chianti Classico Cru from the single 'Il Poggio' vineyard and worked to eliminate white grapes from Chianti Classico Riserva blend. Further, in 1981 Monsanto harvested the first 100% Cabernet Sauvignon, Nemo, from the Il Mulino vineyard.
