| Storage | How long it stays fresh | Best for | Downside |
|---|---|---|---|
| Original bag + clip (dark cupboard) | Two good weeks from opening | Buying at the pace you drink | Air gets in with every opening |
| Opaque airtight canister | Blocks light and air at once; 3–4 weeks | Buying 250 g (9 oz) or more at a time | Washing, drying, and shelf space |
| Clear glass jar | Looks great, ages the beans faster | Display-first kitchens | Defenseless against light — one of beans' four enemies (air, light, heat, moisture) |
| Portioned freezer bags | Holds flavor past a month | Stocking up on sales | Discipline required: thaw only what you use, watch for condensation |
