How to Store Coffee Beans and Ground Coffee

Coffee begins losing aroma after roasting and loses it faster after grinding. Good storage cannot stop this process completely, but it can slow it down. The main enemies are oxygen, heat, light, moisture and repeated temperature changes.

Keep the package sealed

Close the original bag carefully after every use and squeeze out excess air without crushing the coffee. A bag with a one-way valve is designed to release gas while limiting incoming oxygen. If the package cannot be resealed, use a clean airtight container that is not much larger than the amount of coffee inside.

Choose a cool, dry cupboard

Store coffee away from ovens, radiators, direct sunlight and steam. A kitchen cupboard at stable room temperature is normally suitable. Transparent containers may look attractive, but light can accelerate deterioration, so keep them inside a dark cupboard.

Avoid the refrigerator for daily coffee

Refrigerators contain moisture and strong food aromas. Taking the package in and out also creates condensation. For coffee used every day, a sealed cupboard is usually better. Do not open frozen coffee while it is still cold.

Freeze only for longer storage

If you buy a larger quantity, divide unopened coffee into small airtight portions and freeze them. Remove only one portion at a time and allow it to reach room temperature before opening. Do not repeatedly freeze and thaw the same package.

Buy an amount you can use

Smaller, more frequent purchases usually preserve flavour better than keeping a large open bag for months. Grind beans immediately before brewing when possible. Browse available weights in coffee beans and ground coffee.
