Storage tips
- Keep coffee (home ground) sealed in a cool, dry cupboard after opening to hit the window above. It does not need refrigerating.
- Frozen, coffee (home ground) keeps about 1 to 2 years, well past the window above.
- Keep coffee, tea and drink powders airtight in a cool, dark cupboard, away from the kettle and the stovetop. Air, light and damp are what flatten them, not time alone.
How can you tell if coffee (home ground) has gone bad?
- Any mold at the neck or under the cap.
- In dry drinks: a stale, flat or musty aroma, or powder that has clumped hard from damp. These fade in quality long before they become unsafe.

Shelf-life windows come from the USDA FoodKeeper, published by the USDA Food Safety and Inspection Service (public domain); we vendor the FSIS FoodKeeper dataset and refresh it in place. These are quality estimates, not food-safety determinations or guarantees: actual condition depends on storage and handling, and harmful bacteria may not have obvious signs.
