Rum

Distilled from sugarcane. Two raw materials, two traditions, two completely different flavour profiles. Caribbean and Latin American — the world's most geographically diverse spirit category.

Canonical Definition

Rum is a distilled alcoholic spirit produced from sugarcane (Saccharum officinarum) or sugarcane by-products — primarily molasses (the residual syrup from sugar refining) or, for agricole/rhum agricole styles, fresh sugarcane juice (vesou or guarapo). Rum has no single internationally binding production standard — unlike Scotch whisky, Cognac, or Bourbon, which are governed by regulated geographic indications. However, most producing countries have domestic regulations, and the EU definition (Regulation EU 2019/787) requires a minimum 37.5% ABV, production from sugarcane, and no flavourings except caramel colouring. The primary production variables that determine rum's character: (1) raw material (molasses vs fresh juice); (2) fermentation (wild yeast vs commercial yeast, short vs long fermentation); (3) distillation (pot still vs column still vs both); (4) ageing (unaged, short-aged in tropical climate, long-aged in temperate climate). The major rum-producing regions — Caribbean (Barbados, Jamaica, Trinidad, Barbados, Guyana, Cuba, Puerto Rico), Latin America (Guatemala, Venezuela, Panama, Nicaragua, Dominican Republic), and French West Indies (Martinique AOC rhum agricole, Guadeloupe) — each have distinct regulatory and stylistic traditions.

The two raw materials — molasses vs fresh juice

Every rum starts as either molasses or fresh sugarcane juice. This single distinction produces the two most fundamentally different rum styles in the world:

Molasses-based rum — the dominant global style. Molasses is the thick, dark syrup remaining after raw sugar crystals are extracted from sugarcane juice by centrifugation. It contains ~55–65% fermentable sugars (sucrose, glucose, fructose), significant non-sugar organic compounds (amino acids, organic acids, trace minerals), and the characteristic dark, complex flavour precursors that carry through fermentation and distillation. Almost all Caribbean rum is molasses-based.

Agricole / Rhum agricole — fresh sugarcane juice (vesou) is fermented and distilled directly, without the molasses refining step. The resulting spirit is more delicate, grassy, floral, and vegetal — with less of the heavy congener character of molasses rum. Martinique AOC and most French West Indies production is agricole. Many South American rums (cachaça in Brazil, though cachaça has its own legal category) also use fresh juice.

Rum Regulation

Why rum is the least-standardised major spirit: EU 2019/787 and US TTB floors, the AOC Martinique (the only rum appellation), the Barbados and Jamaica GIs, WIRSPA's Authentic Caribbean Rum, and the sugar/additive controversy.
