Rum is an alcoholic beverage produced by the distillation of various fermented cane sugar products. The most common mixtures used in making rum consist of molasses and water or sugar and water. Sugarcane is a type of grass most often found growing in tropical and subtropical regions of the world. Molasses is a byproduct in the processing of sugar. It is a dark brown glutinous liquid containing uncrystallized sugar and some sucrose (a disaccharide composed of glucose and fructose). Alcohol is formed through the actions of enzymes, causing a chemical reaction between organic substances. This process is identified as fermentation, in which the action of zymase secreted by yeast converts simple sugars, such as glucose and fructose, into ethyl alcohol and carbon dioxide. This can be represented by the equation

C6H12O6 → 2C2H5OH + 2CO2.

Another type of rum production involves the fermentation of a mixture of the scum formed from the heating of the raw sugarcane juice with molasses, water, and the residue left after the refining of sugar, known as dunder. In a process known as distillation, the liquid mixture is heated until its volatile components pass into the vapor phase. The vapor is then cooled to recover such constituents in liquid form by condensation. The process of distillation not only concentrates the alcohol, but also removes from the beverage a large portion of the unpleasant-tasting impurities. Once distilled, rum is a white or straw-colored spirit varying in strength from 80 to 150 proof (40 to 75 percent alcohol). Dark rums are made by adding a small amount of caramel or by aging in special wooden casks. The flavor depends upon ethyl butyrate, an organic ester. Annually, the US consumes between 130 million and 154 million liters.
