We had a lovely time visiting vineyards and cycling through Burgundy. The trip was suitable for people who were not in tip-top shape and the terrain was mostly flat (except for one day where we were staying in Chassey-le-camp at the top of a very large hill -- totally unnecessary given that the route then cycled back to the same place we went the day before). If you are visiting a winery, you should call ahead and let them know when you will arrive. Many places close around lunch time. There are lots of picnic benches to stop along the way, especially near Dracy-le-fort, so I would recommend stopping at a grocery store, bakery, etc. in the morning (not to mention a winery!) and creating your own picnic for lunch. You might want to bring your own plates, cutlery, and cups.
