Popcorn Storage: Kernels, Microwave and Popped Bags
Check which kind of popcorn you have. FoodKeeper gives different pantry quality guides for dry kernels, microwave packets and commercially popped bags. The short 1–2-day guide for microwave popcorn applies after it is prepared and the bag is opened.
Quick answer
FoodKeeper gives a pantry quality guide of 2 years from purchase.
This starts at purchase; it is not specifically an unopened-jar estimate. Follow the package's own date and directions.
FoodKeeper gives a pantry quality guide of 1 year after opening the jar.
Do not add this period to the purchase estimate or use opening to reset the age of older kernels.
FoodKeeper gives a pantry quality guide of 6–12 months from purchase. Orville Redenbacher's describes its printed best-by date as a best-quality date.
The FoodKeeper estimate starts at purchase. Follow your exact packet's storage and cooking directions.
FoodKeeper gives a pantry quality guide of 1–2 days after opening the prepared bag.
This means popped microwave popcorn, not an uncooked packet opened before cooking.
FoodKeeper gives a pantry quality guide of 2–3 months from purchase for commercially popped popcorn in bags.
This starts at purchase; FoodKeeper does not identify it specifically as an unopened-bag estimate.
Why guidance varies
Dry popping kernels, microwave packets and commercially popped snack bags share this page, but their storage guidance differs. Homemade popcorn and moist or perishable toppings need their own recipe guidance. Fresh sweetcorn and ornamental seed are outside this guide.

Frequently asked questions
Does an uncooked microwave packet last only two days after opening?
That is not what this FoodKeeper entry means. Its 1–2-day pantry quality guide applies to popcorn that has been prepared and whose bag has been opened. Follow the uncooked packet's own instructions.
Can homemade popcorn with moist toppings use the bagged-popcorn guide?
No. The commercially popped-bag estimates do not cover homemade popcorn with moist or perishable toppings. Follow guidance for the complete recipe and its ingredients.
