151-proof rum is a type of rum that has a very high alcohol content, specifically 75.5% alcohol by volume (ABV). This makes it significantly stronger than standard rums, which typically range from 40% to 50% ABV. The name "151" refers to its proof measurement, which is double the percentage of alcohol. Due to its high potency, 151-proof rum is often used in cocktails and mixed drinks, but it should be consumed with caution. It is also popular for flambéing dishes and creating visually striking drinks, as it can easily ignite. Always handle it responsibly to avoid alcohol-related risks.
