How Long Does Booze Keep?
Wednesday, 14 August 2013 | by Pat's Picks

Alcohol doesn’t come with an expiration date, but does that mean it’s okay to consume really old booze? The Chicago Sun-Times says while “old liquor won’t kill you, it probably won’t thrill you either.” Anything that’s over 80-proof will keep forever as long as the bottle’s seal isn’t broken. The taste, however, won’t improve and if you see anything floating in the bottle or any discoloration, you’re better off dumping it down the drain.
