The Dark ’n Stormy is a delicious, easy-to-make cocktail that features a refreshing trio of dark rum, ginger beer and lime. It also goes down a lot easier than the moody name might imply. It’s a close cousin to the Moscow Mule (vodka, ginger beer, lime) and should be an easy transition for vodka drinkers wanting to try something new, but also familiar. The popular cocktail can be found all over the world, from craft cocktail bars and chain restaurants to island hideaways. Its origin, like that of many drinks, is a bit hazy, though it’s likely that rum and ginger beer were first combined by sailors who enjoyed the obvious benefits of rum and the stomach-settling qualities of ginger. But Dark ’n Stormy’s direct lineage can be traced squarely to one island in the Atlantic Ocean.
