Winery notes: "We only produce this Chianti Classico Gran Selezione in outstanding vintages. When we do make Riserva Ducale Oro, we start by harvesting the grapes by hand, mostly from our Gretole estate in the Chianti Classico appellation. The vineyard lots are vinified individually to preserve their specificity to the land. We age the wine in oak, stainless steel and concrete vats for 36 months, twelve months longer than required by Italian law. The wine then spends additional months in bottle before release."
