How long does home-ground coffee last in the freezer?
1–2 years for best quality at -18°C (0°F). Frozen food stays safe indefinitely; after that, texture and flavour fade.

3–5 months in the pantry, if the seal is intact and it is stored as the label says.
How long is home-ground coffee good for past the expiration date?
FoodKeeper gives unopened home-ground coffee 3–5 months 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.
How can you tell if home-ground coffee is bad?
