Know your units
A glass of wine, for example, can contain one to three units depending on the size of the glass and the strength of the wine.
How do I work out how many units a drink contains?
A good place to start is to find out how many units there are in your favourite drink.
The image shows how many units some of the most common drinks contain.
For example, a single 35ml shot of spirits contains roughly as much alcohol as a small 125ml glass of wine or half a pint of ordinary-strength beer – about 1.5 units.
For more detailed information about how many units different drinks contain visit the alcohol unit page.
Keep in mind! When drinking at home, it’s easy to pour larger drinks – so you could be drinking more than you think.
