18-month freshness guaranteeGood flavour is also dependent on how the coffee is stored. To preserve the full aroma of Black Edition, the coffee comes in aroma-proof bags. A valve allows gases released from the coffee to escape to prevent the bag from overinflating. As aroma may escape from the bag over a longer period of storage time, we recommend using the coffee within 18 months. Of course the coffee can still be used after that time frame.
