Coffee’s enemies are air, light, heat and moisture. Keep beans in their resealable bag with the air pressed out, or in an opaque airtight canister, in a cupboard away from the stove.
Should coffee go in the fridge?
No. The fridge is humid and full of smells that coffee absorbs. The freezer is fine for longer storage if you portion beans into airtight bags and only take out what you will use within a week, without refreezing.
Whole bean or ground?
Ground coffee goes stale in days because so much more surface is exposed to air. If you can, buy whole bean and grind just before brewing.
How long does a bag last?
Unopened, a sealed bag with a one-way valve keeps coffee tasting good for six to eight weeks from roasting. Once opened, aim to finish it within three weeks. That is why our subscriptions default to a size that a typical household drinks in about a fortnight.
