This was an interesting place to visit and taste a number of different wines in one location. The shop is located just off the main road in Greve and down a flight of stone steps so you feel like you're entering a wine cave. Then the place opens up to a massive wine shop with lots of tables and chairs and lots and lots of wine.
You buy a card at the counter and get a book with all the different wine regions and some information on the wines, which was really nice as we had no plans to try and taste everything! They also provide a pencil and paper so you can make notes on your tastings. We were two couples and had a really fun time, trying different wines and then ranking them among ourselves - it was interesting to see how our individual tastes differed and really funny for us to realize that none of us really cared too much for Chianti! Our only complaint is that the staff weren't all that friendly and didn't seem very open to questions or inquiries - an open smile and friendly greeting would be an improvement.
If you like wine and want to just relax and enjoy an afternoon, this is a good spot to do it.
