The general meeting of the Chianti Classico Consortium has voted with a large majority for the introduction of eleven sub-appellations for the top category Gran Selezione. The sub-zones, called UGA (unità geografiche aggiuntive) in Italian, are: Castellina, Castelnuovo Berardenga, Gaiole, Greve, Lamole, Montefioralle, Panzano, Radda, San Casciano, San Donato in Poggio (including Barberino Tavarnelle and Poggibonsi) and Vagliagli. According to the consortium, it is quite possible that the subzones will also be introduced for the Annata and the Riserva in a second step. Another change in the production rules for the Gran Selezione is that the share of Sangiovese will be raised from currently 80 to 90 percent and international varieties will disappear completely. From now on, only other autochthonous red grape varieties from Tuscany may be used for the remaining ten percent.
