Unità Geografiche Aggiuntive (UGA)
Meaning "Additional Geographic Units," this is an Italian designation for subzones of an appellation. Currently it is used in Italy's Tuscany region for 11 subzones of the Chianti Classico appellation. Established by the Consorzio Vino Chianti Classico in 2021, the designation identifies distinctive, historic and enologically significant growing sites in the area. With the first phase of implementation, this designation can only be used for wines at Chianti Classico's highest quality level, gran selezione. The 11 UGAs are Castellina, Castelnuovo Berardenga, Gaiole, Greve, Lamole, Montefioralle, Panzano, Radda, San Casciano, San Donato in Poggio and Vagliagli.
