World's costliest cocktail at 5,500 pounds per glass

The cocktail Salvatore's Legacy by Salvatore Calabrese 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 attempt was made at Salvatore's, Calabrese's bar at the Playboy Club London, in Mayfair, central London, the Skynews reported.

The drink has set a new record for the most expensive cocktail in the world, Calabrese claimed.

The record bid was supposed to take place in July but was delayed when a bottle of one of the ingredients smashed.

"I was devastated when my bottle smashed and thought my dream of breaking the world record was over, but thankfully it has all worked out and nothing will stop me now," Calabrese said.

Guinness World Records said it is investigating the claim, which would topple its current record holder for the most expensive cocktail, a cocktail costing 3,766.52 pounds that is served in a Dubai hotel.

"GWR can confirm that we have received an official claim for the most expensive cocktail record attempt," a spokeswoman for Guinness World Records, said.

"The current record for the most expensive cocktail commercially available is '27,321', costing 27,321 United Arab Emirates dirham (3,766.52 pounds) which can be found on the menu of The Skyview Bar of Burj Al Arab Hotel, Dubai, United Arab Emirates," she said.

"GWR will only be able to confirm if the attempt has been successful or not three working days after we have received the evidence," she added.
