Demerara Rum
Rum from Guyana, made on wooden stills that no longer exist anywhere else in the world. Heavy, smoky and burnt-sugar rich, it is the weight at the bottom of a Zombie and the reason a proper tiki drink tastes darker than its colour suggests.
Quick Facts
Flavour Profile
Primary Flavours
Tasting Notes
Deep burnt sugar and molasses with a distinct woodsmoke note through the middle, finishing dry, dark and considerably less sweet than the aroma promises.
Storage & Handling
Upright, cool and dark, tightly sealed. The overproof expressions are flammable in a way ordinary spirits are not — keep them away from a lit float and treat the 75.5% bottle with the respect it deserves.
Usage
The heavy third of a split-rum tiki build: 30ml in the official Zombie, and a common float or base in the Don the Beachcomber repertoire. Also the traditional rum for a Corn n’ Oil and a natural choice anywhere a drink wants molasses depth without extra sweetness.
The Wooden Stills
Demerara rum is defined by equipment rather than by recipe, and the equipment is irreplaceable.
The Diamond distillery in Guyana operates the last wooden continuous stills in the world: a double wooden pot still from Port Mourant dating to the eighteenth century, a single wooden Versailles still, and the Enmore wooden Coffey still. Wood is porous where copper and steel are not, and the spirit picks up character from the vessel in a way no modern still reproduces. When those stills eventually fail, the style fails with them, which is why they are maintained rather than replaced.
Against Jamaican Rum
Both are heavy rums and they are heavy in opposite directions.
Jamaican rum is loud at the top of the palate: fruit esters, banana, pineapple, a solvent brightness. Demerara is loud at the bottom: burnt sugar, smoke, molasses and a dry, almost tarry depth. A tiki drink that splits its rum between the two is not hedging — it is covering the whole range, with the Jamaican supplying the aroma and the Demerara supplying the floor underneath it. Pour either one alone and the drink sounds like half a chord.
The Overproof Question
Lemon Hart 151 and its equivalents are a different ingredient from the standard bottling, and recipes treat them as such.
At 75.5% the spirit is used in small measures, as a float, or set alight over a garnish, and a recipe calling for overproof Demerara that gets a standard-strength pour will taste underweight without any obvious reason. The reverse substitution is worse: 30ml of 151 where the recipe wanted 40% turns a balanced drink into a hazard. Read which one the recipe wants.
Buying It
El Dorado is the widely available house, and its numbered expressions run from serviceable to genuinely fine.
The 12 and 15 year are sipping rums that also work in a glass; the 3 year white is a useful, characterful base. Lemon Hart is the traditional cocktail name, and its 151 remains the reference overproof for tiki. Hamilton bottles single-still expressions for people who want to taste what a Port Mourant still actually does. Any of them will do what a recipe means by Demerara rum.
Top Tips
- It is a style from one country, not a colour: Demerara means Guyana.
- The overproof bottlings are for floats and flaming, not for pouring by the jigger.
- Substitute a dark rum and you lose the smoke, which is the entire point.
Common Questions
What is Demerara rum?
Rum from Guyana, named for the Demerara river region, and distilled at Diamond on the last wooden stills in the world. It is a style defined by place and equipment rather than by colour or age, and it tastes of burnt sugar, molasses and woodsmoke.
Is Demerara rum the same as dark rum?
No. Dark rum is a colour and frequently means a light rum with caramel added. Demerara is a production origin with a specific heavy, smoky profile. A recipe asking for Demerara wants that weight, and a dark rum substituted in will taste sweeter and considerably flatter.
Why do the wooden stills matter?
Wood is porous and imparts character to the spirit passing through it in a way copper does not. The Port Mourant, Versailles and Enmore stills at Diamond are the last of their kind anywhere, so the style genuinely cannot be reproduced elsewhere.
Do I need the overproof version?
Only where a recipe says so. Overproof Demerara at 75.5% is used for floats, small measures and flaming garnishes. Swapping it for standard strength leaves the drink underweight; swapping standard strength for it makes something considerably stronger than intended.
