The one maize that explodes, at about 14% internal moisture. Dry kernels keep two years; popped and bagged, three months; the microwave packets sit between them because of the fat in them.
How long it keeps
Unopened, this keeps 2 years — which is what puts it on the long shelf.
| As sold | Unopened, in the cupboard | Once opened |
|---|---|---|
| dry kernels in jar | 2 years | 1 year |
| commercially popped in bags | 2–3 months | 1–2 weeks |
| microwave packets | 6–12 months | 1–2 days |
Counted from the day you bought it. Figures are the USDA FSIS FoodKeeper table's, for unopened storage at room temperature; FoodKeeper counts a month as 30 days.
FoodKeeper's own note: After opening time applies to prepared product.
The table was not pulled from USDA — fsis.usda.gov answers 403 to non-browser clients from this machine — so it came from a mirror of the data.gov dataset and its vintage is unverified. Treat a single figure as indicative, not as a use-by date.
