The Agricoltori del Chianti Geografica was formed in 1961 by 17 farmers in order to improve the quality of their produce and its commercial potential. The group now comprises 200 members in the most prestigious area of Tuscany and covers an area equivalent to 571 hectares. Most of that land falls under the DOCG quality standard. Chianti Classico is produced from 250 hectares in the south of the region, at an altitude of between 280 and 600 m above sea level. In the province of Siena, a total of 160 hectares of vines produce Chianti Colli Senesi. The aim of the cooperative is to produce wines that respect the traditions of the various regions of Tuscany whilst paying close attention to technical innovations that might contribute to the quality of the wines.
