Questions this answers
Tap a question for the short answer.
How long does sugar last?
Sugar lasts indefinitely when it is stored airtight and dry, and the label date says the same. Hardening does not change that, since hardened sugar is still usable.
How do I store sugar long term?
Keep it airtight and dry. Stored that way its shelf life is indefinite, and sugar that hardens is still usable.
How do I tell if sugar has gone bad?
The main thing to watch for is hardening, and hardened sugar is still usable. Hardened brown sugar is usually safe, and sugar kept airtight and dry lasts indefinitely.
