Rum is a distilled alcoholic beverage made from sugarcane byproducts, such as molasses, or directly from sugarcane juice, by a process of fermentation and distillation. The distillate, a clear liquid, is then usually aged in oak barrels.
Demerara rum its made on the banks of the Demerara river in Guyana. It is a dark rum with a fuller taste that retains a greater amount of the underlying molasses flavor. Demerara rum is most similar in style to Jamaican rum, but has a smoky, almost burnt flavor that can add complexity to cocktails. Jamaican rums tend to be medium bodied, with plenty of fruity estery aromas that come from the native fermentation of sugars instead of adding cultured yeast. Gold rums, also called “amber” rums, are medium-bodied rums that are generally aged. These gain their dark colour from aging in wooden barrels (usually the charred, white oak barrels that are the byproduct of Bourbon whiskey).
