Under searching last wrote "DUDOGNON", I found this The world's most expensive Cognac. Henri IV Dudognon Heritage.
The name is of course from old French king Henri IV.

Reading the site, the bottle is made from 4 Kg of platinum and gold, with 6,500 pieces of diamond. Within that, over hundred aged GRANDE CHAMPAGNE.
The price is $34 MIlion, it says.

At least for me, that is not interested…
