Dark 'n' Stormy
A simple, yet distinctive and robust highball cocktail, the Dark 'n' Stormy features dark rum (traditionally Gosling's Black Seal) and spicy ginger beer, with a lime garnish, known for its layered appearance.
What is this drink?
The Dark 'n' Stormy is Bermuda's national cocktail — a legally trademarked drink requiring Gosling's Black Seal Rum floated dramatically over spicy ginger beer, with a lime garnish. The dark rum sits on top of the ginger beer like a gathering storm cloud over the ocean, which is exactly how it got its name. It is a highball of remarkable simplicity and equally remarkable character.
Why you'll love it
The float technique that gives the Dark 'n' Stormy its name also creates a genuinely interesting drinking experience — as the rum slowly bleeds down through the ginger beer with each sip, the ratio of rum to mixer shifts, creating a drink that starts spicy and ginger-forward and becomes progressively more rum-dominant. The combination of Gosling's molasses-heavy dark rum and proper ginger beer is nothing short of magnificent.
When to serve
The Dark 'n' Stormy is a perfect summer highball, an ideal beach bar drink, and an excellent companion to spicy food and grilled meats. In Bermuda, it is consumed year-round as a point of national pride. It pairs brilliantly with jerk chicken, fish tacos, and any spiced or barbecued food where the ginger beer provides a cooling, spicy counterpoint.
Pro tip
The float is the defining technique — pour the ginger beer first over ice, then carefully pour the rum over the back of a bar spoon held just above the surface, allowing it to settle on top rather than mix in immediately. Use a genuinely spicy ginger beer (not ginger ale) and Gosling's Black Seal specifically — its particular molasses richness is what makes the trademark meaningful. Squeeze lime directly into the drink before the float for the best integration.
Gosling's Black Seal Rum
The trademarked base spirit of the authentic Dark 'n' Stormy. A Bermudian dark rum with prominent molasses, caramel, and vanilla character. Its rich, sweet depth is specifically designed to float over ginger beer and bleed through it as the drink is consumed.
Spicy Ginger Beer
The essential mixer that provides the drink's characteristic heat and effervescence. A genuinely spicy ginger beer (Barritt's is traditional in Bermuda; Fever-Tree or Reed's work well elsewhere) is non-negotiable — ginger ale does not deliver the same experience.
Fresh Lime
The citrus element that brightens the rich, sweet rum-ginger combination. A squeeze of fresh lime juice stirred gently into the ginger beer before the rum float adds acidity and prevents the drink from being overly sweet.
Swap Options
If Gosling's is unavailable, use another dark, aged, molasses-heavy rum like Cruzan BlackStrap or Kraken. Try Appleton Estate for a Jamaican rum variation with funkier, more fruity character. Replace ginger beer with a mixture of ginger ale and a teaspoon of fresh grated ginger in a pinch. Add Angostura bitters to the ginger beer before the rum float for extra aromatic complexity.
Step-by-Step Instructions
Prepare the glass
Fill a highball glass with 1 serving of ice.
Tips:
- •Using plenty of ice keeps the drink cold and minimizes dilution.
Add ginger beer
Pour 4-5 ounces (120-150 ml) of spicy ginger beer into the glass over the ice.
Tips:
- •Choose a good, potent ginger beer for the best 'kick'.
Float the rum
Slowly pour 2 ounces (60 ml) of Gosling's Black Seal Rum (or chosen dark rum) over the back of a spoon, allowing it to float on top of the ginger beer. This creates the signature 'stormy' layered effect.
Tips:
- •Pouring slowly and carefully is key to achieving distinct layers.
Garnish and serve
Garnish with 1 lime wedge. Do not stir before serving; the layered appearance is part of the drink's appeal.
Tips:
- •The drink is meant to be stirred by the drinker, allowing them to mix the flavors as they wish.

Fun Fact
Bartender's Tips
- While Gosling's Black Seal is traditional, any good quality dark, aged rum can be used.
- The spiciness of the ginger beer is a key component; opt for a spicier brand if preferred.
- Adjust the ratio of rum to ginger beer to your taste.
- A squeeze of fresh lime juice can be added directly to the drink before the rum for extra brightness.
Different ways to make this drink your own
Jamaican Dark 'n' Stormy
Use Appleton Estate or Smith & Cross Jamaican rum instead of Gosling's for a funkier, more tropical character. The Jamaican rum's fruity esters and grassy notes interact differently with the spicy ginger beer, producing a more vibrant, complex variation.
Spiced Dark 'n' Stormy
Add two dashes of Angostura bitters to the ginger beer before floating the rum. The bitters introduce warm spice notes of cinnamon, clove, and gentian that deepen the drink's complexity and add a more aromatic, craft-cocktail quality.
Dark 'n' Stormy Mule
Add a squeeze of fresh lime juice and a small handful of fresh mint to the glass before the ginger beer and rum. This hybrid of the Dark 'n' Stormy and Moscow Mule creates a more citrus-bright, refreshing variation that feels lighter without losing the dark rum's depth.
Tools that make this drink come together
Highball Glass
A tall highball glass gives the Dark 'n' Stormy room for ice, ginger beer, and the floating rum cap, plus a lime wedge garnish. The height showcases the dramatic dark rum float sitting atop the ginger beer below.
Bar Spoon
Pour the dark rum slowly over the back of the bar spoon held just above the surface of the ginger beer. The spoon disperses the rum gently so it floats rather than sinking and mixing. This creates the signature two-tone visual effect.
Citrus Juicer
A squeeze of fresh lime juice is the traditional finishing touch for a Dark 'n' Stormy. A small hand juicer extracts clean lime juice quickly without pressing the bitter pith, keeping the citrus note bright and clean.
Can't Find These?
Any tall glass works. Pour the rum very slowly over a regular teaspoon held above the ginger beer surface — the same technique applies. Hand-squeeze lime directly into the glass before the ginger beer.
The right glass makes a real difference
Highball Glass
A Dark 'n' Stormy is served in a tall highball glass, which provides the height needed to showcase the cocktail's defining visual element — the dark rum floating above the pale ginger beer below. The contrast between the deep amber rum layer and the golden ginger beer beneath gives the drink its name and its theatrical appearance. The highball also accommodates generous ice, helping keep the drink cold as the rum slowly integrates.
Alternatives
A Collins glass is essentially the same shape and works identically. A copper mug (as used for a Moscow Mule) gives a rustic, tactile alternative with better temperature retention. Any tall, wide glass with enough volume is suitable — the dark rum float is the visual priority.
Perfect food pairings to complete the experience
Jerk Chicken
Smoky, spiced Caribbean jerk chicken is the perfect companion to Bermuda's national cocktail. The chilli heat and allspice of the jerk seasoning is soothed by the ginger beer's carbonation while the dark rum's molasses notes complement the smoky marinade.
Coconut Shrimp
Crispy coconut-crumbed shrimp with a mango chutney dipping sauce echo the rum's tropical character. The sweetness of coconut and mango pairs naturally with the dark, molasses-rich Gosling's rum floating above the spicy ginger.
Fish and Chips
The British pub classic works surprisingly well with a Dark 'n' Stormy. The crispy battered fish and salty chips are refreshed by the ginger beer's spice and carbonation, while the rum adds warmth that suits a seaside setting.
Pulled Pork Sliders
Slow-cooked pulled pork with a molasses barbecue glaze shares the caramel and dark sugar notes of the rum float. The ginger beer's heat cuts through the richness of the pork, making every bite feel lighter and more vibrant.
Prep in advance for effortless serving
Chill the Ginger Beer
Refrigerate ginger beer for at least 4 hours before service. Cold ginger beer retains its characteristic heat and carbonation far better when poured, and keeps the overall drink colder without relying heavily on ice.
Pre-Cut Lime Garnishes
Cut lime wedges several hours ahead and store in a small container in the fridge. Fresh lime wedges are always available for garnishing each Dark 'n' Stormy immediately without delay during service.
Pre-Measure the Rum
Portion Gosling's Black Seal rum into small individual shot glasses or a small jug in advance. Having the rum pre-measured means you can float it over the ginger beer in one smooth motion without pausing to measure during service.
Fill Glasses with Ice in Advance
Fill highball glasses with ice and store them in the freezer or a cooler 15 minutes before service. Pre-iced glasses mean assembly happens instantly — pour cold ginger beer, float the rum, and garnish in under 30 seconds per drink.
