Although they sound the same, one drink doesn’t always equal one standard drink...
An alcoholic drink is not pure alcohol – it is a solution which contains varying amounts of ethanol (pure alcohol) and other ingredients. Some alcoholic drinks are stronger than others because they contain a greater amount of pure alcohol (ethanol) in the same volume. The higher the concentration of ethanol in the drink, the stronger the drink and the more standard drinks it will contain.
For example, mid-strength beer is 3.5% alcohol while spirits are approximately 40% alcohol.
What is a standard drink?
A standard (STD) drink is a unit measure of the amount of pure alcohol (ethanol) in your drink.
In Australia, 1.0 STD drink = 10g Ethanol
Below are some examples of typical drinks and how many standard drinks each contains:

To further complicate matters, no matter where you go alcohol is served in different glasses, jars, bottles and jugs. Next time you’re out, take note of the size of the glass your drink is served in – don’t assume that a glass holds one standard drink. A standard restaurant pour of wine is, in fact, 150ml, while 1.0 standard drink of wine is 100ml.
When keeping track of alcohol intake it is more reliable to count the number of standard drinks you have had, than the number of glasses.
