how many units of alcohol in half a bottle of wine

That's a great question, as it can be tricky to keep track of alcohol units. The exact number of units in half a bottle of wine depends on the wine's strength, or its Alcohol By Volume (ABV).

According to the NHS, a unit of alcohol is defined as 10ml of pure alcohol. Since wines can vary in strength, the number of units will change. A standard bottle of wine is 750ml.

To give you a good idea, let's take a typical wine with an ABV of 13%. A full 750ml bottle of this wine would contain about 9.75 units. Therefore, half a bottle (375ml) would have just under 5 units of alcohol. If the wine is stronger, say 14% ABV, half a bottle would be about 5.25 units.

It's helpful to remember the UK's health guidelines, which advise that both men and women should not regularly drink more than 14 units per week, spread over several days. This means that half a bottle of wine can account for more than a third of that weekly recommendation. For the most accurate count, it's always best to check the ABV percentage on the wine label.
