A UK-based cocktail maker claims he has set a new world record for the most expensive cocktail, taking the crown from Dubai's Skyview Bar.
Salvatore Calabrese said Salvatore's Legacy, made using ingredients dating back to before American independence and the French Revolution, costs £5,500 per glass.
Guinness World Records said it is investigating the claim, which would beat the £4,632 cost of the current holder - the 27.321 served at the Skyview Bar located on the 27th floor of the Burj Al Arab.
The attempt was made at Salvatore's, Calabrese's bar at the Playboy Club London, in Mayfair, central London on Thursday.
The cocktail uses four ingredients - a 1778 Clos de Griffier Vieux Cognac, a 1770 Kummel liqueur, a circa-1860 Dubb Orange Curacao and two dashes of Angostura bitters dating from around 1900.
The record bid was supposed to take place in July but was delayed when a bottle of one of the ingredients smashed.
The Skyview Bar cocktail is made from Macallan 55-year-old single malt natural colour whisky, exclusively produced dried fruit bitters 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.
