Several preservation methods of coffee beans

The storage of coffee beans has a direct impact on the quality of coffee beans, especially for coffee beginners, how to preserve your beloved beans? here are some ways to preserve coffee beans.

◎ makes good use of the proportion of carbon dioxide

As far as gas is concerned, the specific gravity of carbon dioxide is higher than that of gas. Therefore, in the same sealed space, carbon dioxide precipitates at the bottom and air floats at the top. After understanding this truth, its applicability can be judged when choosing containers or bags.

◎ uses vertical sealed cans

In turn, the carbon dioxide released by fresh coffee beans will be left at the bottom of the container to form a carbon dioxide layer to protect the coffee beans, and the container is best placed upright to prevent the loss of carbon dioxide in the bottle or bag. Thus it can be seen that upright, tall and open containers are more suitable for preserving coffee beans.

◎ uses a long spoon to fish for coffee beans

The specific gravity of carbon dioxide is higher than that of air, so it is deposited at the bottom of the container. When taking coffee beans, do not use the method of pouring, otherwise the carbon dioxide in the container will be poured out and regeneration will become more and more difficult. It is recommended that you use a long spoon to reach the bottom of the container for coffee beans so as not to lead to rapid loss of carbon dioxide.

◎ uses opaque jars

Light is a catalyst for carbon dioxide, and opaque jars can slow down the speed of oxygen.

Keep ◎ in a cool, dry place.

High temperature is easy to volatilize the aroma of coffee and the excellent substances inside coffee beans, so coffee cans should be avoided in high temperature environment as far as possible, preferably in a cool and dry place.
