24 hours — quickly goes flat and stale
The short answer
Beer (opened) lasts as long as you store it correctly — which can mean anywhere from a few days on the counter to a year in the freezer. The numbers above represent best quality per USDA and FDA guidelines, not absolute safety limits.
Why these numbers vary
Opened beer. Storage life depends on temperature consistency, humidity, packaging, and how fresh it was when you got it. Refrigerators that swing between 38°F and 45°F shave days off these numbers; vacuum-sealing or freezing extends them.
How to tell if beer (opened) is bad
- Flat (no carbonation)
- Skunky smell (light damage)
- Sour off taste
Storage tips
- Drink fresh — beer rarely improves with age
- Refrigerate sealed for longer life
