Dark ’n’ Stormy
The Dark 'n' Stormy is Bermuda's national highball and one of very few cocktails with a legal department. It was born after the First World War, when ginger beer brewed at a Royal Navy officers' club on the island met Gosling's Black Seal, the local black rum, and a sailor observed that the result was the colour of a cloud only a fool or a dead man would sail under. The legal part is not decoration. Gosling's trademarked the name and has gone to court to defend it, which makes the recipe binding rather than traditional: a Dark 'n' Stormy is Gosling's Black Seal and ginger beer, and a version built on any other bottle is a dark rum and ginger beer, often excellent and differently named. The build is the whole theatre. Ginger beer first over ice, lime squeezed if the day calls for it, and the rum poured last and slowly, where its density holds it as a black weather front above the golden fizz.
Glassware: Highball Glass
Garnish: Lime Wedge optional and unofficial
Ingredients
60ml
The rum the law requires: the Dark ’n’ Stormy is Gosling’s registered trademark and legally defined around Black Seal. Its molasses density is also what floats the storm cloud.
100ml
The golden sea under the weather: a fiery, properly gingery brew that stands up to the black rum. A soft ginger ale turns the drink sweet and sleepy.
Instructions
Fill a highball glass with ice and pour in the chilled ginger beer.
Squeeze the lime wedge over the top if using, and drop it in.
Float the Gosling’s Black Seal by pouring it slowly over the back of a spoon.
Serve unstirred, storm intact, with a straw or a stirrer for the drinker.

Expert Tip
Pour the rum last and pour it slowly, over the back of a spoon. Black Seal is dense enough to sit on top of ginger beer if you let it, and that black-over-gold stratum is the drink's entire visual argument. Stirred in advance it is merely weather. Chill the ginger beer properly first. Ice alone will not cool a room-temperature mixer fast enough, and a warm ginger beer goes flat within a minute of hitting the glass, taking with it the fizz that holds the float up. Choose a ginger beer with real heat. The rum is fixed by trademark, so the mixer is the only variable you control, and a soft golden ale of a ginger beer turns the drink sweet and sleepy. Spicier is better here as a rule rather than a preference.
Flavour Profile
The Origin
Bermuda between the wars: the Royal Naval Officers’ Club brewed its own ginger beer, Gosling’s had been blending black rum on the island for a century, and the two found each other with the inevitability of all great island pairings. The name, folklore says, came from a sailor’s remark about the colour of the cloud the rum makes over the fizz. The drink became Bermuda’s calling card and sailed with its yachtsmen into every harbour in the Atlantic.
The Trademark
Gosling's registered the Dark 'n' Stormy as a trademark and has enforced it, which puts the drink in a very small category: cocktails with a legally binding specification. Most trademark claims over cocktail names fail or are never pressed. This one has been pressed, against brands and bars pouring other rums under the name.
Whether a cocktail name should be ownable at all is a reasonable argument to have. What is not in dispute is that the history and the trademark point the same way here. The drink was built on Black Seal in Bermuda, and the rum is not incidental to it: the molasses density is what makes the float work.
Any other dark rum makes an honourable drink. It is simply a dark rum and ginger beer, which is a perfectly good thing to order.
The Ginger Beer
The rum is fixed; the ginger beer is the variable, and it should bite. A fiery, properly gingery brew stands up to the Black Seal’s molasses weight, where a soft golden ale of a ginger beer turns the drink sweet and sleepy. Both our stocked options serve well, and the spicier the better is the rule.
How to Serve It
Ice to the top, ginger beer, then the rum floated slowly over a spoon so it sits as a black stratum: hand it over unstirred and let the drinker stir the storm down into the golden fizz below. The lime wedge is common, pleasant and unofficial. For the same idea in the house voice, the Storm & Spice swaps in Expedition Spiced Rum and makes no legal claims at all.
The Float
The float is not a garnish. It is the reason the drink is built in the order it is built.
Black Seal is dense, heavy with molasses and noticeably more viscous than an ordinary dark rum, so poured slowly over the back of a spoon it will sit on top of carbonated ginger beer instead of mixing into it. What you get is a glass in two layers: gold underneath, near-black above, with a soft edge where they meet.
That gives the drinker control. Stirred straight down, it is a rum and ginger. Left alone and sipped through, the first mouthfuls are ginger beer with a dark top note and the last are considerably heavier. Handing it over unstirred is the point of the exercise.
The Lime Question
A lime wedge is common, pleasant and entirely unofficial. It is not required by the trademarked serve, and Bermudian practice varies.
It does something worth having. Ginger beer is sweet and Black Seal is sweet, and there is no acid anywhere else in the glass, so a squeeze of lime gives the drink an edge it otherwise lacks and stops the second half turning syrupy.
Squeeze it over the top before the rum goes in, then drop the wedge in. Adding it afterwards means squeezing through the float and mixing the drink before it reaches the table, which undoes the pour.
The Spirit
Gosling’s Black Seal RumBermuda’s black rum, blended by the same family since 1806, and the only spirit that can legally make a Dark ’n’ Stormy. Dense with molasses and burnt caramel, and built with enough weight to float on ginger beer rather than sink through it.
Frequently Asked Questions
Does a Dark ’n’ Stormy have to use Gosling’s rum?
Legally, yes: Gosling’s owns the trademark and the cocktail is defined as Black Seal rum with ginger beer, a definition the company has defended in court. With another rum you have made a dark rum and ginger beer, a fine drink under a different name.
Should a Dark ’n’ Stormy be stirred?
It is served unstirred, with the rum floated over the ginger beer as the storm cloud that gives the drink its name. Stirring is the drinker's job, done at the glass and at whatever moment they choose. Stirred behind the bar it arrives as a perfectly good rum and ginger with no theatre left in it.
What is the difference between this and the Storm & Spice?
The Storm & Spice is our own serve, built on Expedition Spiced Rum with ginger beer: the same storm-in-a-glass idea with an openly different rum and no trademark involved. The two drinks are cousins, and naming them separately is what keeps both of them honest.

Storm & Spice
A brooding sky in a glass. The Storm & Spice takes the bones of Bermuda's legendary Dark 'n' Stormy and gives it a warmer, more aromatic soul. Where the original relies on the molasses-heavy depth of Bermudian black rum, this version uses Jerry Can Spirits Expedition Spiced Rum, bringing vanilla, cinnamon, and clove to the party. The spices in the rum do not fight the ginger. They embrace it, creating something that tastes like a storm rolling in over a tropical island at dusk. The original Dark 'n' Stormy was born in Bermuda just after World War I, when British naval officers discovered that their homemade ginger beer, brewed to settle seasick stomachs, tasted considerably better with a splash of the local Gosling's rum. A sailor reportedly held up the drink and remarked it was "the colour of a cloud only a fool or a dead man would sail under." The technique remains unchanged: ginger beer first, rum floated on top to create that ominous two-toned storm cloud effect. Stir it in if you like, but watch the weather roll in first.
Spiced Rum Mule
The Mule format arrived in American bars in the early 1940s as a solution to a surplus problem. John G. Martin of Heublein had the rights to Smirnoff vodka at a time when vodka had almost no presence in America, and Jack Morgan of the Cock 'n' Bull in Los Angeles had a cellar full of ginger beer that was not moving. The two combined their problems into a single drink, served in a copper mug, and the Moscow Mule was born. The Spiced Rum Mule takes the same structure and builds it around a quality spiced rum, which has a more natural affinity with ginger beer than vodka ever did. Where vodka is a neutral vehicle that lets the ginger lead entirely, spiced rum brings its own warm botanical character into conversation with the ginger's heat. Fresh lime keeps both honest, and the syrup rounds the citrus without softening the bite. The copper mug is not incidental to the serve. It conducts cold efficiently and keeps the drink colder throughout.
Cuba Libre
The Cuba Libre was born in Havana around 1900, in the afterglow of the war that gave the drink its toast: Cuba freed from Spain, American soldiers in the bars, and the new American cola meeting the island’s rum over ice. A captain is said to have raised the glass with the independence cry, por Cuba libre, and the drink has carried the slogan ever since. The obvious objection, that this is just rum and coke, misses the one thing the drink insists on: the lime. A proper Cuba Libre squeezes half a lime into the glass and drops the spent shell in, and that acid is what turns a sweet mixer drink into a long cocktail with a spine. Rum and cola is a pleasant habit. The Cuba Libre is a recipe. It rewards the same care as any three-ingredient drink: a characterful rum, a cola with real spice rather than bare sweetness, and everything properly cold.
