Storing coffee beans in an office without wrecking them

Coffee does not go off the way milk does. It goes flat. You will not see it. You will taste it, usually after the bag has sat open in a kitchenette or a warehouse tea room for too long.

Offices are good at ruining beans by accident. The fridge is next to the machine. The bag sits open. Someone tips a new kilogram on top of last month's.

Keep them out of the fridge

Coffee picks up other smells, and bags sweat when they move in and out of the cold. Moisture is unkind to flavour. Room temperature, in a cupboard, away from the dishwasher, is the usual advice. We are not publishing a lab result. We are telling you what wrecks a hopper.

Air is the problem, not light

Keep beans in the bag they arrived in, roll the top down hard, and clip it. If you decant into a jar, use an airtight one and fill it. A half-empty jar is a jar full of air.

Finish the old bag before you open the new one. Do not tip a new kilogram on top of the old one.

Grind at the machine, not in advance

Ground coffee stales faster than whole beans. A bean-to-cup machine grinds per cup, which is why Arico puts a Saeco Royal Plus in rather than asking a kitchenette to live on pre-ground. That is the machine doing the job it was built for, not a flavour guarantee against every café down the road.

If the floor is still using a plunger and a supermarket grind, storage is secondary. The grind is already the limiting factor.

The hopper is not storage

Beans sitting in the hopper overnight are fine. Beans sitting in the hopper for a week while the site is shut are worth clipping back into the bag. Do not store reserve bags on top of the machine, on the fridge, or on a window ledge.

How much to keep on hand

Order what you will drink in a month, not a quarter. A twenty-person site, two cups a day, at about 7 grams a cup (a planning figure, not a specification), gets through roughly 6 to 7 kilograms a month. Your hopper will correct the spreadsheet.

Buying three months ahead to save on delivery is how the last bag tastes tired. Arico delivers monthly for that reason, not as a loyalty scheme.

If the current setup is still instant, pods, or staff buying their own, what office coffee actually costs is the first question. Storage only matters once you have beans worth storing.
