Does coffee lose quality once the bag is opened?

Undoubtedly, once the coffee bag is opened, it starts losing its aroma and flavor properties.
However, our 500g and 1kg coffee bags come with a zip-lock system to help you store the whole coffee beans better than if they were in the coffee maker’s hopper. We recommend keeping the bags in a dry place, away from direct sunlight.
The best option is to store it in an airtight container where you can remove the air before sealing it. This way, you can minimize coffee oxidation as much as possible.
