Rum is a distilled alcoholic beverage made from sugarcane byproducts, such as molasses or honeys, or directly from sugarcane juice, by a process of fermentation and distillation. The distillate, a clear liquid, is then usually aged in oak barrels.
Most rum is produced in Caribbean and North and South American countries, but also in other sugar-producing regions, such as the Philippines and Taiwan. Production is not strictly standardized globally, leading to a wide variety of distinct regional styles and classifications.
Production
Unlike some other spirits, rum has no defined production methods. Instead, it is based on traditional styles that vary between locations and distillers. The vast majority of rum is produced from sugarcane molasses, but French-speaking islands (like Martinique) prefer to use fresh sugarcane juice, resulting in a distinct style called rhum agricole.
Fermentation times vary based on the desired flavor profile, with longer fermentations producing more esters (funky, fruity flavors). Distillation can be done in column stills for a lighter flavor or pot stills for a heavier, more complex spirit. Aging usually takes place in used bourbon casks, but local laws vary regarding minimum aging requirements.
Major Styles & Categories
Light (White/Silver) Rum: Generally clear and has a lighter flavor profile. They are often aged for a short period and then charcoal-filtered to remove any color picked up from the barrel. Primarily used in cocktails.
Gold (Amber) Rum: Medium-bodied rums that have been aged in wooden casks (usually charred, white oak bourbon casks). They have more flavor and a stronger profile than light rum.
Dark (Black) Rum: Aged longer, in heavily charred barrels. They have a much stronger, richer flavor, often with hints of spices, molasses, and caramel. Commonly used in cooking and robust cocktails.
Spiced Rum: Obtain their flavors through the addition of spices and sometimes caramel. Often based on gold rums, though some are significantly darker.
Overproof Rum: Contains a much higher concentration of alcohol than the standard 40% ABV, often reaching 75-80% ABV (150-160 proof). Used heavily in tiki drinks.
Rhum Agricole: Made specifically from freshly squeezed sugarcane juice rather than molasses. Known for its grassy, earthy, and floral flavor profile. Originates mostly from the French Caribbean.
Cachaça: A spirit from Brazil closely related to rum, also made from fresh sugarcane juice. It is the primary ingredient in the Caipirinha.
