Instant coffee past the expiration date
Unopened
FoodKeeper gives unopened instant coffee 1 year in the pantry, counted from the day you buy it. "Best-by" and "sell-by" describe quality and stock rotation, not safety; only infant formula carries a federally required use-by date.
Opened
Once opened, the printed date no longer applies. Count 2–3 months in the pantry from the day you open it.
How to keep instant coffee fresh longer
- Store unopened in a cool, dark place.
- Refrigerate after opening and close tightly.
- Keep away from light and heat, which flatten flavour.
