The number of alcohol units in a bottle of wine varies depending on the size of the bottle and the alcohol strength (ABV) of the wine.
According to information from the NHS, an alcohol unit is defined as 10ml or 8g of pure alcohol. The total number of units in a drink is based on its volume and its alcoholic strength. Therefore, a bottle of wine with a higher percentage of alcohol will contain more units than a bottle of the same size with a lower strength.
As a general guide, a standard 750ml bottle of wine with an ABV of 13% contains around 9.75 units. However, this number can change significantly. A lighter wine at 11% ABV would have closer to 8 units, while a stronger one at 15% ABV would have over 11 units.
To keep health risks from alcohol at a low level, the NHS advises that men and women should not regularly drink more than 14 units per week. These units should be spread over three or more days, with several drink-free days included each week.
