How to preserve coffee beans or coffee powder?

Can coffee beans and coffee powder be refrigerated or frozen in the refrigerator?

Frozen coffee beans and coffee powder attract moisture, which freezes on the surface of coffee beans, and there are many pores in roasted coffee beans, which seal off the water and end the natural chemical reaction of coffee beans, so, the flavor of thawed coffee beans or coffee powder is much better than that at room temperature.

What about refrigeration? And you can't! The circulating moisture in the refrigerator is the biggest natural enemy of coffee beans or powder, and the freezer is full of odors, unless you want to do scientific experiments to see how long it takes to destroy a good bag of coffee beans. By the way, after grinding stale coffee beans into powder, it can be a very effective dehumidifier and deodorant.

The biggest enemies of coffee beans are oxygen, moisture, light and heat.

Coffee beans that have not been opened should be kept in a dry and cool place.

After opening, it should be put into an opaque and airtight ceramic container immediately. If it has the function of pumping into a vacuum, it is better to put it in a dry and cool place.

Do not use plastic or metal containers to prevent coffee beans or powder from inhaling the smell of plastic or metal.

If the container is transparent, be sure to put it in a storage cabinet where there is no light.

The ground coffee powder can only be preserved for a few days without losing its taste, so it needs to be packed in an opaque and airtight container.

Under proper storage conditions, raw coffee beans can be stored for several years, but after baking, the life is greatly shortened, and the deeper the baking degree is, the easier it is to oxidize. This is a natural phenomenon, no matter how good the packaging and storage conditions are. At best, it can only delay the rate of decay. Therefore, if you really want a good cup of coffee, it is recommended that you buy only the amount you can drink within two weeks to a month from the baking date according to your dosage.
