…the historic area, protected by the “Chianti Classico” subzone.
Following publication in the Official Gazette of 20 October 1984, the new regulations approved for the Denomination of Controlled and Guaranteed Origin (DOCG) come into force. The “promotion” from DOC to DOCG introduces further production constraints, many of which have already been adopted by the Gallo Nero companies, as well as a significant remodeling of the ampelographic base.
The minimum and maximum usable percentage of Sangiovese is increased (from 50-75% to 75-90%), just as the platform of complementary varieties is amended: Canaiolo from 5 to 10%, Trebbiano and Malvasia from 2 to 5% (previously from 10 to 30%) and other “recommended or authorized” red grape varieties up to 10%. These also include international varieties such as Cabernet and Merlot, which therefore officially enter the Chianti Classico blend for the first time, whereas the original DOC regulations indicated a maximum quota of 5% for complementary wines, with preference for Colorino.
