What’s a standard drink?


So yes, we know it is only Thursday but we are very close to Summer and of course the Silly Season. When you are out for your next social drink, bring your alcohol tester, and find the guide below helpful.

The National Health and Medical Research Council (NHMRC) defines a standard drink as containing 10g of alcohol (equivalent to 12.5mL of pure alcohol).

However, don’t confuse a serving of alcohol for a ‘standard drink’. One serving of alcohol does not equal one standard drink – a serving of alcohol is usually bigger.

For example, a serving of glass wine is typically 150ml, but 1 standard drink corresponds to 100ml of wine. This means that if you’re having 2 glasses of wine, you might actually be consuming 3 standard drinks, not 2.

Alcoholic beverages in Australia that are served bottles, cans and casks are required by law to state on the label the approximate number of standard drinks they contain.

So if you’re having a bottled drink, be sure you check the label to find out how many standard drinks it is.

However, note that there are many factors that affect your BAC levels. Due to this, there's no real way to calculate how many drinks it'll take to reach 0.05 other than by using a device such an alcohol breath tester. 

First up, if you don't already know what BAC is, then you should read: What is BAC?

Enjoy your time out, but we encourage you to not drink and then drive. Breathalyzers are there for assistance in determining your BAC only.

How much is a standard drink?

Can/Stubbie low-strength beer = 0.8 standard drink

Can/Stubbie full-strength beer = 1.4 standard drinks
100ml wine (13.5% alcohol) = 1 standard drink
30ml nip spirits = 1 standard drink
Can spirits (approx 5% alcohol) = 1.2 to 1.7 standard drinks
Can spirits (approx 7% alcohol) = 1.6 to 2.4 standard drinks
