It was founded in Florence in 1927 with the aim of ensure the quality and authenticity of Chianti wines, which have a long-standing tradition and recognition both in Italy and abroad.

[2] The Consorzio protects and promotes the interests of Chianti wine producers from the provinces of Florence, Siena, Arezzo, Pisa, Prato, and Pistoia.

To address this, winemakers from neighboring areas began producing a similar wine using the same methods and grape blends but outside the Chianti origin zone.

In July 1984, it received Controlled and Guaranteed Designation of Origin (DOCG) status, the highest level of Italian wine classification.

In September 2012, with a Decree of the Ministry of Agricultural, Food and Forestry Policies,[5] the Consortium obtains the Recognition "erga omnes"[6] with the conferral of the task of carrying out functions of protection, promotion, supervision, consumer information and general care of the interests relating to the Chianti D.O.C.G.

The mandate, subsequently renewed every three years, also includes the protection of the Designation of origins of Vin Santo del Chianti, Colli dell'Etruria Centrale and Bianco dell'Empolese.

In July 2018, together with 11 other consortia, it also contributed to the foundation of PROMOVITO,[9] an association that deals with dissemination, information and promotional activities in Italy and abroad by participating in trade fairs and taking advantage of the European funds established by EU Regulation 1305/2013[10] and by the Rural Development Program (PSR) 2014/2020 of the Tuscany Region.

The service is carried out both in Italy and abroad according to specific control plans approved by the Ministry of Agriculture, Food Sovereignty and Forestry.

The service is implemented through the collection and analysis of wine packages, bearing the name CHIANTI on the label, sold by small and/or large retailers (direct sales and HoReCa channel); any discrepancies with respect to the physical and chemical requirements provided for in the Regulations are reported to the competent authorities.

The Consorzio, by virtue of its "Erga omnes" Recognition, oversees and issues, where the conditions set out in a specific internal regulation are met, the inclusion in the label of the name for which it has the mandate.
