The term refers to the alcohol by volume (ABV) content, expressed as twice the percentage of alcohol. A product labeled as 190 proof signifies that it contains 95% alcohol, while a 151 proof version contains 75.5% alcohol. This high concentration of ethanol distinguishes it from typical spirits intended for direct consumption.
Its significance lies in its versatility for applications beyond simply drinking. The concentrated nature makes it useful in creating tinctures, extracts, and sanitizing solutions. Historically, high-proof alcohol has been utilized in scientific and industrial processes due to its effective solvent properties. However, its potency requires extreme caution in handling and dilution.
