Drinking coffee is about freshness, and if the coffee beans are not preserved properly, it will accelerate the aroma loss of coffee beans, thus affecting the taste of coffee, so the preservation of coffee beans is a key point.

The following will share for you: how to save coffee beans:

Roasted coffee beans are easily oxidized by oxygen in the air, which deteriorates the oil quality, volatilizes and disappears aroma, and then accelerates deterioration through temperature, humidity, sunlight and so on. Therefore, the preservation of coffee beans is usually required to be airtight, low temperature and avoid light. Some friends will ask if coffee beans can be stored in the refrigerator. My suggestion is that if unopened coffee beans can be put in the refrigerator, the temperature decreases, the oxidation rate of coffee beans will slow down. However, if the coffee beans have been opened, it is not recommended to put them in the refrigerator. Among the important elements that affect coffee, moisture has the greatest impact on the taste of coffee. Coffee beans will absorb moisture and the taste will deteriorate to a large extent. The suggestion for the preservation of coffee beans after opening is to put the coffee beans in a special sealed can or use a special sealing strip (clip) and store them in a cool and dry place after sealing.
