Based on the provided information, the number of alcohol units in a drink depends on its size and its alcohol strength. One unit of alcohol is defined as 10ml or 8g of pure alcohol.
While the provided text does not state the exact number of units for a full bottle of wine, it establishes the principle for calculating it. The total units are based on the volume and the alcohol percentage. A typical 750ml bottle of wine can vary in strength. For example, a 750ml bottle of wine with an alcohol by volume (ABV) of 12% would contain 9 units. A stronger wine, perhaps with a 14% ABV, would contain 10.5 units in the same size bottle.
To stay within the low-risk guidelines mentioned in the context, both men and women are advised not to regularly drink more than 14 units a week. This is equivalent to about six medium (175ml) glasses of 13% wine, or less than one and a half bottles of that same wine, spread over three or more days. It is always best to check the bottle's label for its specific ABV to accurately calculate the units.
