How is white rum aged?

Quick answer

Many white rums are not aged at all, and some are aged in barrels and then filtered to remove the color. Rum in the US must be made from sugar cane and bottled at 40% ABV or more, but there is no legal definition of light or dark based on color. Check the producer's information to see which kind a bottle is.

Is white rum aged?

It depends on the brand. White rum is clear, but clear does not mean unaged. There are two common approaches, and a bottle label often does not tell you which one was used.

Approach What happens
Unaged The rum is bottled shortly after distillation, often after resting in tanks
Aged then filtered The rum rests in barrels, then filtering (often charcoal) removes the color

Some producers state that their white rum was aged first and then filtered, and the time in oak differs by brand. I did not verify specific timings, so check the maker for the figures on any bottle.

What do the rules say?

US federal rules define rum as spirits distilled from sugar cane materials, such as juice, syrup or molasses, distilled at less than 95% ABV and bottled at no less than 40% ABV. They do not define white, light or dark rum by color. Article text from the Daily Meal makes the same point: there is no legal definition of light or dark rum based on color.

Why filter?

Barrel aging can add color and flavor, and filtering removes the color. Some tasters say filtering also removes some desirable flavors, but this is a matter of opinion.

How to tell which kind you have

  • Look for statements such as aged for one year then charcoal filtered on the label or maker’s site.
  • If nothing is stated, assume you cannot tell.
  • Taste: aged and filtered rums often feel slightly rounder, though this varies.

Which to use

White rum is often used in mojitos and daiquiris. The choice between unaged and aged-filtered is a matter of taste and budget.

Drink responsibly and only if you are of legal age.
