I have been to it quite a few times. It is very small. There are a bunch of booths, each represented by one of the good wineries that surround Panzano. These booths circle a small piazza. You buy your wine glass and then move around the booths trying the wine. The restaurants are packed and it can be hard to get into one if you're there at lunch time.... it can be experienced in a few hours. I have never noticed music or things like that going on in the evenings during the Fest, but I suppose there could be.....
