Stronger or more concentrated than the standard proof level, especially referring to alcoholic beverages above 100 proof.
From 'above' + 'proof,' combining directional adjective with the term 'proof' (a measure of alcohol content established through spirit testing).
The word 'proof' itself comes from old tests where spirits had to burn gunpowder to prove their strength—'aboveproof' spirits could set more things on fire.
