Standard Drink of Alcohol

What is a Standard Drink of Alcohol? Many people are surprised to learn what counts as an actual drink. In Canada, a "standard drink” is any drink that contains about 13.45 grams of "pure" alcohol. 1 Know what a standard drink is so that you know how much alcohol you are actually drinking.


One Standard Drink Equals: 1

  • 341 ml (12 oz) bottle of 5% alcohol beer, cider or cooler
  • 43 ml (1.5 oz) shot of 40% hard liquor (vodka, rum, whisky, gin, etc.)
  • 142 ml (5 oz) glass of 12% alcohol wine
  • Remember that high alcohol % beers, coolers, cider and fortified wines contain more than one standard drink.
