What is rum made from?

Sugarcane. Most rum in the world is distilled from molasses, the thick byproduct left after sugar is crystallized out of cane juice. A smaller and distinct category, rhum agricole, is distilled from fresh-pressed cane juice instead, which is why it tastes grassy and vegetal rather than sweet and caramelized.

What is the difference between rum, ron, and rhum?

They are the three broad style families, roughly following the colonial languages of the Caribbean. Ron is the Spanish style — light, column-distilled, clean, from places like Cuba, Puerto Rico, and Panama. Rum is the English style — heavier, often pot-distilled and funky, from Jamaica, Barbados, and Guyana. Rhum is the French style, and rhum agricole specifically is made from fresh cane juice in Martinique, Guadeloupe, and Haiti.

What is navy strength rum?

Rum bottled at 57% ABV, equal to 100 degrees proof on the old British scale. The figure comes from a real Royal Navy test: spirit at that strength, if spilled on gunpowder, still allows the powder to ignite, so a purser could not water down the ration undetected.

What is rhum agricole?

Rum distilled from fresh-pressed sugarcane juice rather than molasses, made chiefly in Martinique, Guadeloupe, and Haiti. It tastes grassy, vegetal, and briny rather than sweet. Rhum Agricole Martinique holds a protected AOC designation with enforceable rules covering cane varieties, yields, and distillation.

Does a 12-year-old rum mean the same thing as a 12-year-old whisky?

No. Rum aged in the tropics matures far faster than spirit aged in Scotland or Kentucky, with annual evaporation losses commonly cited around 6 to 10 percent versus roughly 2 percent in cooler climates, so a tropically aged 12-year rum can present like a much older whisky. Rum labeling is also far less regulated: some age statements refer to the youngest rum in the blend, some to the oldest, and "Solera" numbers frequently refer to neither.

Do rum producers add sugar to rum?

Many do. Unlike Scotch whisky, rum has no single global standard, and in several producing countries it is legal to add sugar, glycerol, or flavoring after distillation without disclosure. Independent testing has found substantial added sugar in a number of well-known bottlings. If a rum tastes noticeably sweet neat, that is often why.

What rum should I buy first for tiki drinks?

An aged Jamaican rum, because it does the most work across the canon — it is the base of the original Mai Tai and a major component of the Zombie. Add a clean light rum for Daiquiris second, and a Demerara third. Those three cover most classic tiki recipes.

Rum 101: how to read the bottle

Rum is the least regulated major spirit category on earth. Scotch has law behind every word on the label; rum has marketing. That is why two bottles that both say “aged 12 years” can be entirely different propositions, and why the same word means three things depending on which island printed it.

This is the page we wish someone had handed us. What rum actually is, the three families worth knowing, the words that mean something and the words that don't, and the six bottles that will let you build every drink in the canon.

What rum is

Rum is distilled from sugarcane. That is the entire definition, and it splits immediately into two paths.

Most rum comes from molasses — the thick, dark syrup left over after sugar is crystallized out of cane juice. Molasses is stable, cheap, shippable, and full of character, which is why the overwhelming majority of the world’s rum is made this way.

A smaller category comes from fresh cane juice, pressed and fermented within hours of cutting. This is rhum agricole, and it tastes so different from molasses rum that treating them as one spirit is the single most common mistake people make in this category.

The three families

Style tracks the colonial language of the island more closely than anything else. It is a crude map, and it works.

Spanish style

ron

Where —: Cuba, Puerto Rico, Dominican Republic, Panama, Venezuela, Nicaragua, Guatemala
How —: Molasses, column-distilled, usually lightly aged and filtered
Tastes like —: Clean, light, faintly sweet, easy
Reach for it in —: The backbone of a Daiquiri or a Piña Colada, where the rum should be bright rather than loud

English style

rum

Where —: Jamaica, Barbados, Guyana, Trinidad, and the wider former British Caribbean
How —: Molasses, frequently pot-distilled, longer fermentations, often blended
Tastes like —: Heavy, funky, banana-and-overripe-fruit esters — what the trade calls hogo
Reach for it in —: The engine of the Mai Tai, the Zombie, and anything that needs to punch through citrus

French style

rhum agricole

Where —: Martinique, Guadeloupe, Marie-Galante, Haiti (where it's called clairin)
How —: Fresh-pressed sugarcane juice rather than molasses, distilled on a creole column
Tastes like —: Grassy, vegetal, olive-briny, unmistakably a plant
Reach for it in —: A Ti' Punch, and splitting the base of a Mai Tai to rebuild the lost original rum

Plenty of rum sits outside this map — Brazilian cachaça, Bermudian black rum, the whole New England and Australian traditions — but if you can place a bottle in one of these three, you can predict how it will behave in a drink.

The words on the label

Pot still: Batch distillation. Keeps heavy congeners, so the spirit carries more flavor and more funk. Jamaica's signature.
Column still: Continuous distillation. Strips out congeners for a lighter, cleaner spirit. The Spanish-style default.
Hogo: From the French haut goût. The funky, fruity, faintly rotting-banana note in high-ester Jamaican rum. A compliment.
Dunder: The acidic residue left in the still after a distillation, added back into the next fermentation to drive ester production. Some Jamaican distilleries keep muck pits for exactly this.
Demerara: Rum from Guyana, named for the river. Made partly on wooden stills — including a wooden Coffey still and the Port Mourant double wooden pot — that exist nowhere else on earth. Deep, smoky, molasses-heavy.
Navy strength: 57% ABV, or 100 degrees proof on the old British scale — the strength at which spilled spirit will still let gunpowder ignite. Not marketing: an actual naval acceptance test.
Overproof: Anything above 50% ABV, but in practice usually the 151-proof (75.5%) bottlings used for floats and flames. Handle carefully and never pour near an open flame.
Agricole: Made from fresh cane juice, not molasses. Rhum Agricole Martinique is a protected AOC with real rules about cane, yield, and distillation.
Solera: A fractional blending system borrowed from sherry. A "Solera 15" is usually not a 15-year rum — the number often refers to the age of the oldest fraction in the system, or to nothing much at all.
Blackstrap: Rum coloured and flavoured with the darkest, most mineral grade of molasses. Very dark, faintly bitter. The Jungle Bird's natural home.

Why age statements lie

Not maliciously, usually. Just differently from what you have been trained to expect by whisky.

Heat accelerates everything. A barrel in Barbados does far more work per year than a barrel in Speyside, and the evaporation loss reflects it — commonly cited around 6 to 10 percent a year in the tropics against roughly 2 percent in Scotland. A tropically aged eight-year rum can present like a much older whisky. Older is not automatically better here; a lot of rum is over-oaked by fifteen.

The number does not always mean what you think. In some regimes the age statement refers to the youngest rum in the blend, which is the honest convention. In others it refers to the oldest. And “Solera 15” usually refers to neither — solera is a blending method, not an age, and the number attached to it is often closer to decoration than disclosure.

The practical rule

Trust the distillery, the still type, and the country before you trust the number. A five-year pot-still Jamaican will do more for a Mai Tai than a twenty-three-year solera anything.

The sugar problem

Here is the thing the category does not advertise: in much of the rum world it is legal to add sugar, glycerol, or flavoring to the bottle after distillation, and no one has to tell you.

Independent testing — most visibly by hydrometer analysis published by enthusiasts and by a Swedish state alcohol monopoly — has found significant added sugar in a number of extremely well-known bottles, in some cases tens of grams per litre. It is not a scandal so much as a style choice that happens to be invisible.

It matters for cocktails specifically, because every tiki recipe is balanced on the assumption that the sweetness is coming from the syrup you measured, not from the spirit. If your Daiquiri keeps coming out cloying with the spec followed exactly, suspect the rum.

The six-bottle shelf

Six bottles will build essentially every drink in The Canon. Buy them in this order; the first three alone cover most of it.

The Jamaican

Funk and backbone. Powers the Mai Tai and the Zombie.

Look for: Appleton Estate, Smith & Cross, Doctor Bird, Hamilton Jamaican Pot Still

The light Spanish style

The clean base for Daiquiris and Piña Coladas.

Look for: Probitas, Plantation 3 Stars, Flor de Caña, Real McCoy 3

The Demerara

Depth and smoke. Non-negotiable for Navy Grog and Zombies.

Look for: El Dorado, Hamilton Guyana 86, Lemon Hart

The rhum agricole

Grass and brine. Split it with the Jamaican in a Mai Tai.

Look for: Rhum J.M, Neisson, La Favorite, Clément

The overproof

Floats, and the 151 in a Zombie or Rum Runner.

Look for: Lemon Hart 151, Hamilton 151, Plantation OFTD

The navy rum

Rich, dark, and the only correct base for a Painkiller.

Look for: Pusser's

No affiliation with any of these producers — they’re just what we pour. Add orgeat, falernum, and an orange curaçao and the shelf is genuinely complete.

How to taste it

Neat, in a small glass, at room temperature, before you decide anything. Water second — a few drops opens up a cask-strength rum the way it opens up whisky.

What to look for, in order: sweetness (is it coming from the wood and the cane, or has it been added?), funk (that banana-and-solvent ester note, the sign of pot distillation and long fermentation), wood (vanilla and coconut mean American oak; dried fruit and spice mean ex-sherry or European), and finish (does it go clean, or does it leave a syrupy coat?).

Then make a Daiquiri with it. Three ingredients and nowhere to hide is still the fastest way to find out what a rum actually is.
