What is Alcohol?

Common term for ethanol, a compound produced when glucose is fermented by year. The alcohol content of a particular drink is controlled by the amount of yeast and length of fermentation.

· Fruit is used to make wine and cider, while cereals such as barley and rye form the basis of beer and spirits.

· Alcohol is a drug that has the immediate effect of altering mood, makes people feel relaxed, happy and even euphoric, but alcohol is a depressant, it switches off part of the brain that controls judgement, leading to loss of inhibitions. Drinking even small amounts of alcohol can affect physical co-ordination.

The liver breaks down and eliminates alcohol from the body. It takes 1 hr to deal with 1 unit of alcohol (8g)
