The battle for the world's most expensive cocktail remains a fierce one with many bars and restaurants promoting a cocktail that is made pricey by the addition of a piece of jewelry plunked inside. But one of the world's most expensive hotels sounds like the perfect place to enjoy the new contender in the ultra costly cocktail sweepstakes. The chief mixologist at Skyview Bar in the Burj Al Arab in Dubai has created the "27.321," named for the cost in UAE dirham (27,321 AED which is about $7,450) the floor where the Skyview Bar is located (27th) and the height of the Burj Al Arab (321 meters). The cocktail is made from Macallan 55 year old single malt natural color whisky, exclusively produced 'dried fruit bitters' that carry and support the whisky's flavor, and homemade passion fruit sugar. The resulting cocktail is then served over ice cubes made of water from the Macallan distillery in Scotland, along with an oak stirrer made from a Macallan Cask. The cocktail is presented in a Baccarat 18-karat gold glass, which the buyer gets to take home.
