How to tell if ground coffee is bad

Bulging carton, cap or can — discard.

Ground coffee past the expiration date

Unopened

FoodKeeper gives unopened ground coffee 2 years 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 1 month in the fridge or 2 weeks in the pantry from the day you open it.

How to keep ground coffee fresh longer

  • Critical to be stored in an airtight container.
  • Do not return to freezer once taken out.
  • Store unopened in a cool, dark place.
