You should definitely visit this place if you are in the Saint Emilion area. We went there expecting a regular / standard wine tasting tour and when we started walking to the caves/tunnels we were like... ok, this is new! The guide not only gave us an explanation of the history of Chateau Franc Mayne, but she was extremely knowledgeable about the history of the region and explained to us in such detail everything that we saw in the limestone tunnels.
I do not remember the name of our guide, but she was a girl that was in Napa for a little while, she was the nicest person.
