Alcohol proof

Alcohol proof is a measure of how much alcohol is in a beverage. In the United States, proof is calculated by doubling the percentage of alcohol by volume (ABV). For example, a drink that is 40% alcohol by volume is 80 proof. Proof indicates the strength of the alcohol; higher proof means a stronger drink. This system helps consumers understand the potency of alcoholic beverages, influencing choices for responsible consumption. Different countries may have varying definitions and systems for measuring alcohol content, but the concept of proof remains a common reference point.
