We have had may enquiries from members of the public asking us to clarify what a 'Unit' is - See below for the NHS Guidlines
How Much is a unit?
1 unit is 10ml (8g) of pure alcohol in a 25ml single measure of spirits (ABV 40%), a third of a pint of strong lager (ABV 5.2%) or half a 175ml 'standard' glass of red wine (ABV 12%). ABV stands for 'alcohol by volume'.
Different brands may be stronger or weaker, some manufacturers put the number of units on bottles and cans, but you can always ask bar staff if you are not sure. That way you can keep count of units when you're out drinking.
Pub Measure Guide at a glance - (There is no fail-safe guide to how much you can drink to stay under this limit. The amount and type of alcholic drink, your height, weight and metabolism will all play their part.)
