The most famous festival of Greve in Chianti is "La festa del vino", the wine festival. It takes place in the first week of September during the harvesting of the grapes. This festival is important for people who lives in Greve because it's the reward for all the hardwork to produce the wine.
The flowers festival takes place in the first week of May and it's really beautiful to see the main square entirely covered by a multicoloured carpet of flowers.
The first Monday after Easter and the first Monday of October a famous antique market is held in town, you can find unbelievable stuff!
Every Saturday morning there's the typical market of the town, here you'll find hats, bags and everything to wear. Even the most attractive food, porchetta for instance is a really good gastronomic speciality!
