Traditionalists will insist on floating the rum on top of the ginger beer, but depending on your bartender, a Dark ‘n Stormy is presented either layered or mixed. Don’t be afraid to gently stir it upon consumption so that each sip gives you the perfect amount of rum and ginger beer every time. Or, you can purchase Goslings Dark ‘n Stormy cocktail pre-made in a convenient 8.4oz can — no mixing required.
