Burgundy questions

Good evening to you all,

I have a 4 day trip to Burgundy in about 10 days time. I have visits lined up at various domaines, including chateau Meursault, domaine Olivier Leflaive, Faiveley and Dubreuil Fontaine.
If any Burgundy enthusiasts have any questions that you would like me to ask at the domaines I will be happy to take them with me. A limit of 5.
You can ask anything you like BUT please nothing about price.
I will post answers on my return.
