About 3–5 weeks in the pantry, according to USDA FoodKeeper v128.
Coffee (home ground, non-vacuum) is shelf-stable at room temperature: cool, dry pantry, sealed — refrigerating after opening is optional and mainly preserves quality. Refrigerating it mainly preserves quality rather than safety.
Look for: Sour or off smell; Cloudiness, sediment, or curdling; Fizzing in a still drink, or a swollen carton or can; A bitter or 'off' first sip. Those are the general signs for beverages — USDA FoodKeeper v128 publishes no spoilage note for Coffee (home ground, non-vacuum) specifically. Never taste something to test it — when in doubt, throw it out.
Yes — USDA FoodKeeper v128 gives about 1–2 years in the freezer at 0°F (−18°C). Frozen food stays safe indefinitely; that window is about quality, not safety.
