The Chianti Classico regulation determines the conditions and the requisites that permit a wine to be decked out with the name Chianti Classico D.O.C.G..

The rules provide for a minimum ratio of 80% for Sangiovese, the typical red variety of the zone. Along with the Sangiovese, other red grapes of the area can be used in a maximum percentage of 20%.

These grapes include natives like Canaiolo and Colorino as well as international varieties like Cabernet Sauvignon and Merlot, all recommended and/or authorized for the production zone.

Other requisites requested include a minimum alcohol level of 12 degrees for young wines and 12.5 degrees for the Riserva.

In addition, the regulations note that the processes of winemaking, preservation and bottling must occur exclusively in the production zone.

And the wine may not be released for consumption before October 1.

Minimum required maturation for the Riserva is 24 months including three months of bottle fining.

The label must contain the indication ‘Chianti Classico’ with the more specific identification, Denominazione di Origine Controllata e Garantita and display the year when the grapes were produced (vintage).
