The short answer
Peanut Butter 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
Ground peanut spread. 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 peanut butter is bad
- Rancid smell (oily/off)
- Color darkening
- Mold (rare)
- Hardness throughout
Storage tips
