The edict identified four main areas: Chianti Classico (in the areas of Panzano and Greve), Carmignano (west of Florence), Pomino (east of Florence), and Valdarno di Sopra (the area where Il Borro is located). The Valdarno di Sopra DOC was officially established in 2011, certifying the exceptional value of a region that, since the Renaissance, has been considered ideal for the production of great wines.
