We will be in Florence for three days. We have already booked a group tour to the Brunello Region from Siena. Is there anyway to visit Wineries that are not as expensive from Florence without booking another 120 euro tour?
Try contacting Andrea Amadei. He (yes he! Apparently Andrea is a guy's name in Italy!) has an enoteca/wine shop with a huge ion of wines from across Italy. I am not sure if you have to book, but we just stumbled across his store when we were in Florence and he opened a couple of bottles for us. Lovely guy. http://www.andreaamadei.com/
