That's a great question, and the way alcohol content is measured can be a little confusing!
The alcohol by volume (ABV) percentage you see on a bottle or can refers to the concentration of alcohol in the entire container. It's a measure of what percentage of the total liquid is pure alcohol.
So, if you have a 750ml bottle of wine that says "12% ABV," it means that 12% of the entire 750ml of liquid is pure alcohol. This ratio is consistent throughout the whole bottle. The percentage doesn't change whether you have a small sip, a full glass, or the entire bottle; the liquid is always 12% alcohol.
Think of it like this: the ABV tells you the strength of the drink itself, not the total amount of alcohol you're consuming. The total amount of alcohol depends on how much of that drink you have. A glass of that 12% wine will have the same concentration as the liquid left in the bottle.
