The importance of coffee packaging: how it keeps your coffee fresh
Exposed to air coffee will degrade quickly due to a combination of moisture and oxygen. Coffee releases CO2 formed during roasting for up to 28 days. This CO2 also negatively affects flavour and it is recommended to degas for at least 7 days. So it is important to protect the coffee from moisture and oxygen quickly after roasting, yet we need to get rid of the CO2. Voila, there is the high barrier coffee bag with one-way valve. We can then further improve with Nitrogen-flushing all air out of the coffee bag before sealing.
