Ethanol (CH3CH2OH) is a clear, colorless liquid with a distinct odor and is the alcohol found in alcoholic beverages. In addition to its other physical properties (Table 1), alcohol is flammable and volatile, lending it to be used as a solvent, an antiseptic, a fuel, in thermometers, and in other laboratory procedures. As a psychoactive substance, it is one of the most widely consumed recreational drugs by humans. It suppresses certain functions of the brain while causing the classic symptoms of intoxication including slurred speech, unsteady walk, and disturbed sensory perceptions.

This process is catalyzed by zymase, an enzyme in yeast which changes simple sugars into ethanol and carbon dioxide. This fermentation reaction is represented by the equation in Figure 1.
