Overview

Ethanol, also called ethyl alcohol, pure alcohol, grain alcohol, or drinking alcohol, is a volatile, flammable, colorless liquid. It is a psychoactive drug and one of the oldest recreational drugs. Best known as the type of alcohol found in alcoholic beverages, it is also used in thermometers, as a solvent, and as a fuel. In common usage, it is often referred to simply as alcohol or spirits.

Ethanol Production

Ethanol is organically produced by fermentation in a variety of microorganisms including yeasts and bacteria. Ethanol fermentation is an art that has been employed for thousands of years and is of significant commercial and recreational value. Commodity ethanol is valued according to its purity while consumption ethanol is valued by creating a palatable beverage and their production processes have these emphasis. Fermentation requires a carbohydrate rich feedstock, a fermentative microorganism, and a chamber to protect from contamination and control conditions. Beers are filtered, while liquors and commodity ethanol is distilled to a higher purity.
