This weekend is the annual "Rassegna del Chianti Classico" in Greve, in the square, Piazza Matteotti. One of the larger public tastings of the season, this is the 19th version of this annual event.
There is food and or course a lot of great wine, from producers large and small. This year the tasting glass is €10. The event runs from September 11th to 13th (in the evening only on Friday, all day Saturday and Sunday).
