The Etruscans made wine here before Rome existed; the merchant republics sold it across medieval Europe — the ledgers of Datini, the merchant of Prato, price it barrel by barrel. In 1716 Cosimo III drew legal boundaries around Chianti and three other zones, among the earliest delimitations in wine, and mezzadria sharecropping shaped the hills into the vine-and-olive landscape the world knows.
Sangiovese rules the galestro schists and alberese limestone of the interior. When the DOC rules of the 1960s enshrined a diluted Chianti, Sassicaia and Tignanello answered from outside the law — the super-Tuscan revolt that pulled the whole region back to ambition.
