Proof
Proof is a measurement of alcohol content in spirits, representing twice the percentage of alcohol by volume (ABV). For example, 100 proof means 50% alcohol content. In spirits production, this term is crucial as it indicates the strength of alcoholic beverages and is used throughout the distillation and quality control process. Understanding proof is essential for everyone working in spirits production, from distillers to quality assurance specialists, as it affects production methods, legal requirements, and final product specifications.
