White Rum

Where it started

The light style is a product of the column still and of Spanish-colonial rum making. Rums with fewer congeners, the flavor compounds other than ethanol, are called light, and they tend to come from countries first colonized by Spain, such as Cuba, the Dominican Republic, Puerto Rico and Venezuela.⁴

Where and how it's made

Most white rum starts with molasses. In Puerto Rico's description, the fresh cane juice, called guarapo, is boiled down to crystallize sugar, and the residue, molasses, is what gets fermented.⁵ Distillation is usually continuous: columns are built from trays where descending liquid meets rising vapor, and the vapor gets richer in alcohol as it climbs.⁵ Light rums tend to have short fermentations and are distilled to higher purity, which is why they carry fewer congeners.⁴

U.S. law does not require rum to be aged at all, and an age statement on rum is optional.² Some places add their own rule: Puerto Rico law requires a minimum of one year in white oak barrels, and the rum must be produced on the island.⁵ So how does an aged rum come out clear? Difford's notes that some white rums are aged for as long as three years, with much or all of the color removed by charcoal filtration.³

Strength is set by law too. In the U.S. any rum is bottled at not less than 80 proof (40 percent),¹ while the EU minimum is 37.5 percent, so a European white rum can legally be a little lighter than an American one.⁶

How to taste it

Taste it neat and slightly cool in a small glass, then in a simple Daiquiri: rum, lime and sugar shows the spirit honestly. Look for sugar cane, vanilla, coconut or banana; a harsh or hot finish means the rum was built for mixing, not sipping. Pairings: ceviche, fried plantain, a Cuban sandwich.
