Contact with air will accelerate the oxidation of coffee beans. With the decrease in the number of coffee beans, the gap in the container is getting bigger and bigger, so you should fill the container with materials such as cotton to reduce the extra space. Put the coffee beans in a hot and humid place, the surface of the coffee beans will be oily, at this time, the coffee beans have been oxidized, aroma loss, flavor no longer. When preserving coffee beans, they should be protected from direct light and should not be placed in high-temperature places such as near the heater.

At room temperature, roasted coffee beans can be kept fresh for two weeks. Refrigerating in the refrigerator will prolong the retention period and keep it fresh for about a month. However, when you open the refrigerator to pick up and put the coffee, the temperature difference with the outside will produce water fog, which accelerates the deterioration of the coffee beans. When cold storage or cryopreservation, the coffee beans can be divided into small pieces with food bags or plastic wrap, and the required amount can be taken out when in use. At the same time, we should wait for the coffee beans to return to normal temperature before grinding.
