Keep the original valve bag when it works.
Reseal it tightly, squeeze out excess air and keep it in a dark cupboard.
Protect beans from air, heat, light and moisture.
A good bag in a cool cupboard is often enough for coffee used steadily. The important part is avoiding repeated exposure and buying an amount that matches the household.

A smaller fresh bag can outperform a large bargain bag left open for weeks.
Load only what the grinder needs.
A clear hopper exposes beans to light and the warm environment around the machine.
Daily storage
Keep beans sealed in a cool, dry and dark place away from ovens, windows and steam from the coffee station.
- Reseal immediately after dosing
- Use dry scoops and hands
- Label roast or open dates
Containers
An airtight or air-displacing container can help when used correctly, but transferring beans also exposes them and creates another surface to clean.
- Choose a food-safe container
- Keep it clean and fully dry
- Avoid oversized containers full of air
Freezing
Freezing can preserve sealed portions for longer storage. Moisture and repeated warming are the main risks.
- Freeze in small airtight portions
- Thaw a sealed portion before opening
- Do not repeatedly return the same bag to the freezer
The grinder hopper
A hopper is convenient but not ideal long-term storage. Oils and fragments also build inside the grinder over time.
- Use a quantity consumed reasonably soon
- Keep the lid fitted
- Clean only as the grinder manual allows
Freshness is not one exact day
Roast style, packaging, storage and brew method change the useful window. Judge by aroma, flow and taste rather than a rigid expiry slogan.
