Ethanol results from fermentation of sugar, and various types receive different kinds of sugar alcohol. For the production of beer is used millet, maize or rice, but mainly barley grain. Beer, like wine through a fermentation reaction, reaction with yeast or sugar contained in the main ingredient - cereal grains in the case of beer or fruit for wine. As a result of fermentation of yeast can occur up to a beverage containing 13% alcohol, so the production wysokoalkoholowych beverages such as vodka, gin, whiskey, brandy, etc. takes a bit longer. In order to increase the alcohol content of liquids containing small quantities shall be subjected to distillation, which relies on zagotowaniu fluid, cooling it and skondensowaniu. The basis of this process are different boiling point of water and alcohol - water boils at a lower temperature, so the liquid evaporates and remains with a higher alcohol content.
