I'm doing a quick trip next month to Florence, and will be taking a bus into Greve in Chianti for a day trip. Does anyone have a recommendation for wine shops in this area? I may rent a bike, but was really looking to just walk around with perhaps a quick 20min walk to Montefioralle. (Although with current temps in the high 90's, I may pass on that and opt to sit in a piazza sipping vino )
