Preservation is the process of extending the shelf life of items by reducing their chemical aging. In the case of coffee, optimal preservation means not only maintaining the freshness of the coffee longer, but also preventing the loss of flavor. Proper storage is crucial for coffee preservation and involves protecting the beans from light, odors, heat, moisture and especially oxygen. It is recommended to store coffee in an airtight container in a dark, cool and dry place. Whole coffee beans are best preserved, but if already ground coffee is used, it is important not to transfer it to another container to minimize flavor loss.

Similar storage principles apply to coffee pods as to ground coffee, as the paper filter sleeve offers limited flavor preservation. Flavor compounds can be protected by using resealable flavor packs. It is important to avoid contact of coffee with oxygen during preservation, as oxygen leads to oxidation of oils, fats and waxes contained in coffee. This can cause the coffee to develop a rancid taste and suffer significant flavor loss. Avoiding oxygen is critical for effective preservation of coffee flavor.

Coffee beans should be stored in an airtight container in a dark, cool and dry place, away from light, odors and moisture. Whole beans are preferred, but if ground coffee or coffee pods are used, it is important to minimize contact with oxygen. Oxygen can cause oxidation and affect the quality and taste of the coffee. By following these preservation methods, coffee lovers can enjoy their beverage fresh and flavorful longer.
