High Quality Content by WIKIPEDIA articles! A standard drink is a notional drink containing, amongst other components, a specified amount of alcohol. The standard drink is used in many countries to quantify alcohol intake. It is usually re-expressed as a measure of beer, wine, or spirits for convenience. One standard drink always contains the same amount of alcohol regardless of container size or type of alcoholic beverage. The standard drink varies significantly from country to country, from 7.62 ml (6 g) of alcohol in Austria to as high as 25 ml (19.75 g) in Japan. The value of one standard drink does not necessarily reflect a typical serving size in its country. In Britain the term unit of alcohol is used instead to underscore this point. For example, a typical drink of 1 pint of ale of five percent alcohol by volume contains 2.8 units.
