What's a standard drink?

In Australia one standard drink is any drink that contains 10 grams of alcohol. All bottles, cans and casks of alcohol packaged for sale are required by law to state on the label the approximate number of standard drinks contained.

It can sometimes be difficult to estimate standard drinks in real-life situations because:

  • Glass sizes vary
  • People share drinks (e.g. jugs, casks or bottles of alcohol)
  • Glasses are topped up by other people
  • Composition of mixed drinks is not known (cocktails or punch).
