ABV is an acronym that stands for "Alcohol by Volume" in English, or "Teor Alcoólico por Volume" in Portuguese. It is a measure that indicates the percentage of alcohol present in a drink in relation to its total volume.

For example, if a drink has an ABV of 10%, that means that 10% of the drink's total volume is pure alcohol. ABV is often used to categorize and identify alcoholic beverages such as beer, wine, spirits and cocktails, helping consumers understand how strong a beverage is in terms of alcohol content.
