Why do coffee beans need to be refrigerated in summer?

Summer is a hot season, and the high temperature and humidity will have an adverse effect on the quality of coffee beans. Therefore, many people think it is a good idea to refrigerate coffee beans in the summer. So why do coffee beans need to be refrigerated in the summer? This article will explain this issue from several aspects.

Keep it fresh

First, refrigeration can help keep coffee beans fresh. At high temperatures, the oils in coffee beans will become more susceptible to oxidation. As a result, the coffee beans will lose their original flavor and aroma. By storing coffee beans in a refrigerator or other low-temperature environment, the rate of oil oxidation reaction can be effectively slowed down.

Prevent moisture

Secondly, storage in a humid environment may lead to mold and bacteria growth, and may also cause moisture to accumulate inside the bag. These will have an adverse effect on the quality of the coffee beans. By refrigerating the coffee beans, the humidity in the environment can be reduced, thereby reducing the possibility of mold and bacteria growth and keeping the inside of the bag dry.

Prevent oxidation

In addition, refrigeration can also prevent coffee beans from being exposed to too much air. When coffee beans are exposed to air, the substances in them will react with oxygen, resulting in the loss of taste and aroma. By sealing the coffee beans and storing them in the refrigerator, you can effectively reduce contact with air and slow down the rate at which they react.

Avoid heat

Finally, storing coffee beans in high temperatures in the summer may cause them to spoil due to heat. High temperatures will cause the moisture inside the coffee beans to evaporate too quickly and may also cause some chemical changes. These will have an adverse effect on the flavor and quality of the coffee beans. Therefore, refrigerating coffee beans in the summer is a good way to avoid the problem of heat spoilage.

in conclusion

In summary, the main reasons why coffee beans need to be refrigerated in summer are to maintain freshness, prevent moisture, prevent oxidation, and avoid heat. By storing coffee beans in a refrigerator or other low-temperature environment, the speed of oil oxidation reaction can be effectively slowed down, humidity can be reduced, the possibility of mold and bacteria growth can be reduced, contact with air can be reduced, and heat deterioration can be avoided. Therefore, refrigerating coffee beans in summer is a recommended practice.
