About alcohol

Alcohol (also known as booze and other nicknames) is the common name for ethanol or ethyl alcohol. Pure ethanol is a clear and colourless liquid. It is the intoxicating substance present at varying levels in alcoholic beverages such as beer, wine and spirits.

How alcohol is made

Beer, wine and cider are made through a fermentation process. Fermentation is a natural biological process in which yeast changes sugar into alcohol. It makes drinks with lower alcohol concentration (4% to 15%).
