Our driver, Allesandro, was simply outstanding. Worth a try to request him. The tour of Castell di Querceto was just right and and our young hostess was lovely and well informed. As for the tasting three very "shallow" pours with one of the three being a dessert so, for me it doesn't really count. Good stuff, but it would have been an appropriate gester to ask if anyone wanted a fuller taste of their favorite. If I could do it again we would have bought a bottle to sit and drink right there. In any event, it was a good experience and Allesandro made it outstanding.
With this tour we were able to bypass the cue, which was at least a couple hour wait. Our tour guide was great. This is advertised by Viator as a way to get in and walk around on your own. You can do that, but you'll miss a great tour, so stick with the guide.
