does alcohol by volume mean per serving

[DelLeo]

Alcohol by Volume, commonly abbreviated as ABV, does not indicate the amount of alcohol per serving. Instead, it is a standardized measure representing the concentration of pure ethanol within the total volume of an alcoholic beverage, expressed as a volumetric percentage.

The ABV percentage signifies a consistent ratio of alcohol to the total liquid, which is uniform throughout the entire container. For example, if a 750 mL bottle of wine is labeled as 12% ABV, it means that 12% of the total 750 mL volume is pure alcohol. This concentration is the same for the entire contents of the bottle.

Consequently, this same percentage applies to any portion or serving size dispensed from the container. A 150 mL glass poured from that bottle will also contain a liquid that is 12% alcohol by volume. While the total quantity of alcohol consumed is directly dependent on the volume of the serving, the concentration, or ABV, remains constant. The percentage is a property of the liquid itself, not a measure tied to a specific serving size or container.
