A standard 750ml bottle of wine typically contains around 9 to 10 units of alcohol. This depends on the alcohol by volume (ABV) percentage, with a common estimate being about 10 units for a bottle with 13.5% ABV. The number of units can be calculated by multiplying the wine's volume (ml) by the ABV (%) and dividing by 1,000. For example:
- A 750ml bottle of wine with 13.5% ABV contains roughly 10 units of alcohol.
- Lower ABV wines (e.g., 10-12%) will contain fewer units, around 7.5 to 9.
- Higher ABV wines and fortified wines can contain more units, sometimes up to 15 or more units per bottle.
This means that a bottle of wine is equivalent to about 3 large glasses of wine in terms of alcohol units.
