Can it sit out?
Home-ground coffee is shelf-stable, so sitting out at room temperature isn’t the safety question — storage time is.
How to tell if home-ground coffee has gone bad
- Grounds that smell of nothing when the jar opens
- A thin, papery cup with no bloom on the pour-over
- Damp, caked grounds from a jar left open
When in doubt, throw it out.
Keep the grinder’s burrs clean — stale oil in the chamber flattens fresh grounds on contact.
