How long does instant coffee last?
Instant coffee keeps 1 year sealed and 2–3 months once the jar is open — it pulls water straight out of the air, so the lid matters more than the date.

Can it sit out?
Instant coffee is shelf-stable, so sitting out at room temperature isn’t the safety question — storage time is.
How to tell if instant coffee has gone bad
- Granules fused into a solid puck
- A stale, burnt-cardboard smell in the jar
- Crystals that won’t dissolve cleanly in hot water
When in doubt, throw it out.
Use a dry spoon every single time — one wet one turns the whole jar to brick.
