Short answer: Popcorn (dry kernels in jar) keeps 2 years (1 year once opened) in the pantry.
Storage chart

| commercially popped in bags | 2–3 months; 1–2 weeks (after opening) |
| microwave packets | 6–12 months; 1–2 days (after opening) |

Common questions
How long does popcorn last at room temperature?
2 years (1 year once opened) in a cool, dry pantry.
How can I tell if popcorn has gone bad?
Throw it out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
