There's an old saying with bartenders, "If you have to ask, you can't afford it." JK
That being said, we got the scoop on the Louis XIII Rare Cask which is different and more expensive than the traditional Louis XIII.
The bottles of Rare Cask (RC) cost in upwards of $30,000 each.
DCL is the only cruise line in the world with them. They have 2 bottles, one on Dream and one on Fantasy. They were delivered to the ship with armed guards.
When we were on dream, a glass/shot cost $1300. The portion is served in a Baccarat crystal glass, which you keep, and if you are a lady, you get a diamond fleur-de-lis pendant, if you are a gentleman, you receive diamond fleur-de-lis cufflinks.
The taste is so smooth and velvety that it lingers on your palate for hours, if not days.
There was also an option to purchase a taste for $200, which amounts to a few drops.
