Royal Bermuda Yacht Club is a vintage cocktail made with a combination of rum, orange liqueur, lime juice, and falernum liqueur. In order to prepare it, all ingredients should simply be shaken with ice, then strained into a chilled cocktail glass.
If desired, the drink can be garnished with a lime wheel. This pre-Tiki cocktail was originally invented by Trader Vic at the eponymous club. The club was established in 1844, and it was often frequented by British Army Officers.
