Gosling Ginger Beer Making a delicious Dark ‘n Stormy is a breeze. As always, start with two ounces of deep, rich Gosling’s Black Seal Rum in a tall ice-filled glass. Then, top with our perfectly balanced ginger beer; the only ginger beer created strictly to make Dark ‘n Stormy cocktails. We didn’t steer you wrong on the whole shorts thing. Trust us on this one, too. We spent over a year to achieve the ideal balance of sweetness and spiciness and matching it to the flavour profile of our award-winning Black Seal Rum. Only our Black Seal Rum makes a Dark ‘n Stormy genuine. Our Ginger Beer makes it perfect. It's now much easier to make Bermuda's national drink.
