What Does Barrel Proof Mean
Barrel proof (also known as cask strength) refers to whiskey that is bottled directly from the barrel without dilution, retaining the original alcohol content as it matured. This results in a higher proof—typically between 100 and 140 in the United States—and offers a more concentrated flavor profile. The term is regulated in some jurisdictions, ensuring the whiskey’s alcohol percentage matches that of the barrel at the time of bottling.
