The first attempt to classify Chianti wine in any way came in 1427, when Florence developed a tariff system for the wines of the surrounding countryside, including an area referred to as "Chianti and its entire province". In 1716 Cosimo III de' Medici, Grand Duke of Tuscany, issued an edict legislating that the three villages of the Lega del Chianti (Castellina in Chianti, Gaiole in Chianti and Radda in Chianti) as well as the village of Greve and a of hillside north of Greve near Spedaluzzo as the only officially recognised producers of Chianti. This delineation existed until July 1932, when the Italian government expanded the Chianti zone to include the outlying areas of Barberino Val d'Elsa, Chiocchio, Robbiano, San Casciano in Val di Pesa and Strada. Subsequent expansions in 1967 would eventually result in the Chianti zone covering a very large area all over central Tuscany.
