How long does white sugar last?
Updated 2026-05-13 · USDA FoodKeeper & FDA guidelines
Pantry / counter
2 years
Indefinite if dry — quality 2 years
The short answer
White 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 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 white sugar is bad
- Hardened brick (still safe — break up)
- Bugs
- Off smell
Storage tips
- Airtight to prevent moisture/bugs
- Hard sugar: bread slice in container softens it
