How long does sugar last?
Updated 2026-05-13 · USDA FoodKeeper & FDA guidelines
Pantry / counter
indefinite
Indefinite — sugar doesn't spoil
The short answer
Sugar 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
Granulated white sugar. 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 sugar is bad
- Hardening (still usable — break up)
- Bug infestation (rare)
Storage tips
- Hardened brown sugar: bread slice in container softens it
- Doesn't actually expire
- Airtight container prevents moisture
