I personally am not a fan of the drink Cognac. It’s really strong and, I guess, an acquired taste. I do like Pineau des Charentes which has cognac in it and I really like the city of Cognac and its history.
I once did a tour of the Hennessy building showing the barrels used for storage and how the whole process works. Their boutique is very elegant and rather bare. I mainly went in to see if there was a toilet, which there was.
