The storage of coffee beans directly affects the quality of coffee beans. Several preservation methods of coffee beans

Coffee beans storage directly affects the quality of coffee beans, especially for coffee beginners, how to preserve your beloved beans, the following to recommend you a few coffee beans several preservation methods.

* Use carbon dioxide properly

Carbon dioxide has a higher specific gravity than gases. So, in the same sealed space, carbon dioxide settles at the bottom, and air floats at the top. Understand this truth, in the choice of containers or bags, you can judge its suitability.

◎ Use upright sealed cans

Similarly, carbon dioxide released by fresh coffee beans will remain at the bottom of the container, forming a carbon dioxide layer to protect the coffee beans; and the container should preferably be placed upright to prevent carbon dioxide from being lost in the bottle or bag. Thus, upright, tall, thin containers with upward openings are more suitable for storing coffee beans.

·Use a long spoon to remove coffee beans

Carbon dioxide has a higher specific gravity than air, so it settles at the bottom of the container. When taking coffee beans, do not pour them, or the carbon dioxide in the container will be poured out, and it will be more and more difficult to regenerate. It is recommended that you use a long spoon to reach the bottom of the container for coffee beans, so as not to cause rapid loss of carbon dioxide.

* Use opaque jars

Light is a catalyst for carbon dioxide, and opaque canisters slow down oxygen.

·Keep in a cool, dry place

High temperature is easy to volatilize the aroma of coffee and the fine substances inside the coffee beans. Therefore, coffee cans should be avoided as much as possible in high temperature environments, and it is best to place them in cool and dry places.
