Gosling’s Black Seal Rum
Bermuda’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.

Tasting Notes
Deep molasses and burnt caramel with a dark spice edge: a black rum built to read through ginger beer from the top of the glass.
Storage & Handling
Sealed and upright, out of direct light.
Usage
The Dark ’n’ Stormy is its kingdom, by recipe and by trademark: Gosling’s registered the cocktail and has litigated to keep other rums out of it. Beyond the highball it is a fine heavyweight dark rum for punches, floats and any spec calling for black rum with molasses depth.
Bermuda Since 1806
The Gosling family has been blending rum in Bermuda since 1806, and the Black Seal name comes from the black wax that sealed the bottles customers brought to be filled from the barrel. The rum is the island’s definitive export and one half of its national highball, born when ginger beer brewed at a Royal Navy officers’ club met the local black rum.
The naval connection is not decoration. Bermuda was a Royal Navy station, ginger beer was brewed there, and the drink assembled itself from what was locally to hand rather than being invented by anybody in particular.
The Trademarked Cocktail
What makes the bottle unusual in the cocktail canon is the paperwork. Gosling’s trademarked the Dark ’n’ Stormy in the United States and has defended it in court, making it one of the very few cocktails with a legally enforceable recipe. A dark rum and ginger beer made with anything else is a fine drink and a different name.
Bartenders have complained about this for decades, and the complaint is understandable and beside the point. The mark exists, it has been litigated, and a bar menu printing the name while pouring something else is making a claim it cannot support.
What Black Rum Means
Black rum is a description of colour and weight rather than a protected category, and much of that colour comes from added caramel rather than from time in wood. That is not a scandal, since the style is honest about being a blended, coloured rum built for mixing rather than a single-cask sipper.
It is worth distinguishing from blackstrap, which is a separate thing again: a rum made with blackstrap molasses, drier and more bitter, and the traditional pour in a Corn n’ Oil. Black Seal will stand in there and the drink comes out sweeter.
In the Glass
The density is the working property. Poured over ginger beer rather than under it, the rum hangs at the top of the glass as the cloud that names the drink, then stirs down through it. Building the drink the other way round loses the effect entirely and is the usual reason a Dark ’n’ Stormy arrives looking like a highball.
Beyond that it is simply a characterful heavyweight dark rum, and it goes wherever extra molasses weight suits: punches, tiki floats, and any spec asking for black rum.
Top Tips
- If the menu says Dark ’n’ Stormy, the glass should contain Black Seal: it is the rare cocktail with a legal spec.
- Its weight floats: pour it over the ginger beer, not under, and the drink builds its storm cloud on its own.
- Treat it as a dark rum with the volume turned up: it stands in for standard dark rum anywhere extra molasses suits.
Possible Substitutions
- Another rich black rum: makes an excellent dark rum and ginger beer, which is a different drink by law
- Blackstrap rum: heavier and more bitter, for drinkers who want the storm darker still
Production Method
A blend of aged distillates coloured and deepened to the near-black Bermuda style the Gosling family has bottled since the nineteenth century, originally sold from the barrel into sailors’ own bottles sealed with black wax: the Black Seal.
Common Questions
Why must a Dark ’n’ Stormy use Gosling’s?
Because the name is a registered trademark held by Gosling’s, and the company has sued to enforce it: the cocktail is legally defined as Black Seal rum with ginger beer. Other rums make a dark rum and ginger beer, which can be excellent, but not a Dark ’n’ Stormy.
What does Black Seal taste like?
Deep molasses, burnt caramel and dark spice at a standard 40%. It is a black rum with enough density to float on ginger beer and read from the top of the glass downwards, which is as much a physical property as a flavour one.
What else can I make with it?
Anywhere dark rum works and extra weight helps: punches, tiki floats, and a Corn n’ Oil if the blackstrap has run out, though the drink comes out sweeter that way. It is a characterful black rum first and a trademark second.
Is black rum the same as blackstrap rum?
No. Black rum describes colour and weight, much of it from added caramel rather than from wood. Blackstrap is made with blackstrap molasses and is drier and more bitter. Black Seal will stand in for blackstrap and the drink arrives sweeter for it.
