Rum styles explained, from light and dark to spiced and aged

What rum is

Rum is a spirit distilled from sugar cane products. Most rum is made from molasses, the thick, dark syrup left over when sugar is refined. Some is made from fresh cane juice. The sugary liquid is fermented with yeast, then distilled and usually diluted and bottled, sometimes after ageing in wooden casks.

Unlike Scotch whisky or Cognac, rum has no single set of global rules. Each country decides its own minimum ageing, what can be added and how terms such as dark or aged may be used. That freedom is why rum is so varied. It is also why labels can be confusing.

White, gold and dark

These three words are the most common on rum labels. They describe colour more than anything else.

White or light rum is clear. It may be unaged, or aged and then filtered through charcoal to remove the colour. It tastes clean and light, which is why it is the base for mojitos and daiquiris.

Gold rum has some colour, usually from a period in casks, sometimes from added caramel. It tastes a little rounder.

Dark rum is deeply coloured, often with caramel added. Many dark rums taste of molasses, toffee and dried fruit. A dark colour does not always mean long ageing, so read the label for an age statement if that matters to you.

Pot still and column still

How a rum is distilled changes its character more than its colour does. A column still distils continuously and produces a light, clean, high-strength spirit. A pot still works in batches and keeps more of the heavy, fruity and funky flavours from fermentation.

Jamaica is famous for heavy pot still rums with intense tropical fruit and banana notes from long fermentations. Many light Spanish-heritage rums from Cuba and Puerto Rico are column distilled and filtered for a clean, crisp style. Many brands blend the two.

Aged rum and the effect of heat

Aged rums spend years in oak casks, often ex-bourbon barrels. They gain vanilla, spice, toffee and wood. Most rum is aged in the tropics, where heat speeds up the reaction between spirit and wood. More spirit also evaporates each year than in a cool Scottish warehouse. Our guide to whisky maturation and casks explains the same process for whisky.

Some rums carry an age statement. Others use a solera system, where younger rum is topped into older casks over time, so the number on the label may describe the oldest rum in the blend rather than the average. Read the small print.

Spiced, navy and overproof

Spiced rum is rum flavoured with spices such as vanilla, cinnamon, clove and orange peel. It is usually sweetened. It is easy to drink with cola or ginger ale.

Navy rum is a blended dark rum style linked to the British Royal Navy's old daily rum ration. It is rich, full and often bottled stronger than standard rum.

Overproof rum is bottled well above normal strength, sometimes over 60% ABV. It is mainly used in small amounts in cocktails. Treat it with care.

Rhum agricole and cane juice rums

In the French Caribbean, especially Martinique, rhum agricole is distilled from fresh sugar cane juice rather than molasses. It tastes grassy, vegetal and fresh, quite unlike a molasses rum. Martinique rhum agricole has its own protected designation with strict rules.

Brazil's cachaça is also made from fresh cane juice and is the base of the caipirinha, though it is a separate category with its own rules.

Rum in India

India grows a lot of sugar cane and has a long rum tradition. Most Indian rum is made from molasses. Dark, sweet rums are especially popular. A growing number of craft producers now make aged, spiced and cane-based rums too. Our guide to molasses and grain spirit in India explains the base.

In warm weather, try rum long: with soda and lime, in a highball or with coconut water. Taste rums side by side to learn the styles, keep pours small, drink water alongside and never drink and drive.

A simple tasting flight teaches more than any label. Pour a white, a gold, a dark and a spiced rum in small measures, add a few drops of water to each and compare the aroma first, then the taste. You will quickly find which style you prefer.

Common questions

What is the difference between white and dark rum?

Mainly colour, from cask ageing or added caramel. Dark rum often tastes richer, but a dark colour does not always mean long ageing.

What is rhum agricole?

A rum distilled from fresh sugar cane juice rather than molasses, mainly from the French Caribbean. It tastes grassy and fresh.

Is spiced rum the same as dark rum?

No. Spiced rum is flavoured with spices and usually sweetened. Dark rum describes colour and style, though some spiced rums are also dark.

Is Indian rum made from molasses?

Most of it is. Dark, sweet rums are especially popular. Some craft producers also make aged, spiced and cane-based rums.
