Incidence and history of alcohol use
In 1997, Americans drank an average of 2 gallons (7.57 liters) of alcohol per person. This translates roughly into one six-pack of beer, two glasses of wine and three or four mixed drinks per week. About 35 percent of adults don't consume alcohol, so the numbers are actually higher for those who do. Alcohol is an amazingly popular social phenomenon. Alcoholic beverages have been widely consumed since prehistoric times by people around the world. It was being used as a component of the standard diet, for hygienic or medical reasons, for their relaxant and euphoric effects, for recreational purposes, for artistic inspiration, as aphrodisiacs, and for other reasons.
Structure of alcohol
Ethanol, the active ingredient in alcoholic beverages, is almost always produced by a process called fermentation. Fermentation is in fact the metabolism of carbohydrates by certain species of yeast in the absence of oxygen. Alcoholic beverages with a concentration of more than 50% ethanol by volume are extremely flammable liquids and easily ignited. Flavoring ethanol has also become a sort of ritual! Ethanol is a moderately good solvent for many fat substances and essential oils, and thus facilitates the inclusion of several coloring, flavoring, and aromatic compounds to alcoholic beverages, especially to distilled ones.
Sometimes the flavor is obtained by allowing the beverage to stand for months or years in barrels made of special wood.
