How many units in a glass of wine?

Answer 1

This depends on the strength of the wine and the size of the glass, though a medium 175ml glass may contain around 2.4 units, whereas a larger (250ml) glass can contain around 3.5 units.

An easy way to calculate the units in wine is to take the % strength (ABV), and multiply by the volume (ml), then divide by 1000, as follows

%ABV x ml = X

X/1000 = units.

So, for 175ml of wine at say 13% strength:

13 x 175= 2275

2275/1000 = 2.275 units.

Your standard bottle of wine at 13% would thus contain approximately 10 units.

Answer 2

Well take into the consideration your body size, and legal BAC (blood alcohol content). However many drinks you can consume without your blood becoming alcohol-enriched to an illegal amount is the "legal limit".

in the UK it is 125ml and 175ml and multiples thereof

Answer 3

There is no such measurement as a legal drink.-

In the UK there are very strict requirments under the Sales of Goods Act and the Weights and Measures act.

If you sell wine by the glass, you must display the quantity

The quantities permitted are 125ml, 175ml or multiples of these. You can have a separate sign or table card, or else show this on the menu, wine list or price list.

Glasses used for measuring wine must be crown stamped, and 125ml, 175ml or multiples of these sizes

Four fluid ounce glasses still in use on the premises must not be used as they are illegal.

Stamped wine glasses must be stored separately from any unstamped ones, which are used for bottles of wine and other drinks?

If you sell wine by the carafe, your carafes must be crown stamped and in 250ml, 500ml, one litre or two litre sizes only any other measure used for selling wine is illegal.

Answer 4
