The "Emozioni dal Chianti" is an annual three day event set up in Piazza Repubblica. It usually takes place sometime between the middle of September and October. and there is a wide variety of Chianti specialties to taste and buy (wine, olive oil, salamis, honey, crafts, etc.) along with lots of promo materials for local Chianti towns. Worth checking out if you are in Florence and looking for things to do in Chianti this fall.
