San Giusto a Rentennano, a name of Etruscan origin, overlooks the upper course of the Arbia river in the farthest south Chianti Classico wine zone. The estate began life as a medieval monastery of Cistercian nuns and was called San Giusto alle Monache (“of the Nuns”). In 1204 it was fortified by the Florentines, after a treaty established it as their boundry with Siena. Only portions of the ancient fortification still stand, its crenellated battlements, massive barbican wall and underground vaults, used today as the ageing cellars for our wines.The medieval estate of San Giusto a Rentennano came into the Martini di Cigala family through marriage in 1914. In 1957, it was inherited by Enrico Martini di Cigala and in 1992, by his nine children. Today Anna, Lucia, Elisabetta, Francesco, Alessandro and Luca are partners in the estate company.
