I’ve learnt about Tuxedo cocktail from David Wondrich’s Esquire Drink Database. So I thought that it’s made exclusively with sherry. Once enjoying Tuxedo with genever and dry sherry, I started to search for more information about this cocktail. To my shame, it appears that Tuxedo was a well-known and popular cocktail in the first half of 20th century.
The oldest source I could find, Harry Johnson’s «New And Improved Bartendes’ Manual» described Tuxedo as a cocktail with French vermouth, not sherry.
Later sources, «The Savoy Cocktail Book» and «Approved Cocktails, authorized by UK bartenders guild» also mentioned Tuxedo with vermouth. Moreover, «The Savoy Cocktail Book» contains two Tuxedo versions.
