When coffee becomes a daily life, more and more people become inseparable from coffee, go to coffee shops to drink coffee every day, and even buy their own fresh coffee beans and make coffee at home. But fresh coffee beans are also alive, so preserve them well to ensure that the coffee will not lose its original fragrant flavor because of improper storage.

●

Make 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 air. Therefore, in the same confined space, carbon dioxide precipitates at the bottom and air floats at the top. After understanding this truth, when you choose a container or bag, you can judge its applicability.

●

Use upright sealed cans or sealed bags

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

●

Use a long spoon to get coffee beans

The proportion 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 reverse method, otherwise the carbon dioxide in the container will be poured out and regeneration will become more and more difficult. It is recommended that the right thing to do is to use a long spoon and reach out to the bottom of the container to get the beans, so as to avoid the rapid loss of carbon dioxide.

●

Use an opaque jar or bag

Light is the catalyst of oxidation, and opaque jars or bags can slow down the rate of oxidation.

●

Use vacuum cans or vacuum bags

There are more and more vacuum cans on the market, and the price is also quite cheap. This kind of jar will be equipped with a mechanism, that is, by pulling or pressing, the air in the jar can be pumped out to form a vacuum. A vacuum indicates that there is no oxygen or water vapor, which is a good place to store coffee beans.

●

Put it 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 or coffee bags should be avoided in a high temperature environment, preferably in a cool and dry place.

●

Matters needing attention in refrigerator storage

Of course, the low temperature in the refrigerator can slow down the natural deterioration of coffee, and it is a good place to store coffee, but there are many conditions in the refrigerator, which must be eliminated in order to effectively protect coffee beans; otherwise, it will be counterproductive.

Because the air in the refrigerator is cold and dry, it is easy to evaporate the moisture in the beans and lose the fragrance, and there are too many odors in the refrigerator, so even if you put it in the refrigerator, you still need to use sealed cans or sealed bags to store coffee beans.

When coffee beans are first taken out of the refrigerator, because the temperature of the beans is too low, they will condense water vapor in the air and form water droplets on the surface. After grinding, these droplets will lump the coffee powder, causing uneven brewing. Therefore, the coffee beans should be taken out of the refrigerator before use. after taking some of them, put the vacuum jar back into the refrigerator as soon as possible, and grind and brew the coffee quickly. If the whole bag of coffee beans is not put back in the refrigerator, it should be taken out one hour before use, and then unsealed after returning to normal temperature at room temperature, so that water droplets will not form on the surface of the coffee beans.

In addition, the internal development of coffee beans is still in progress after roasting, and the flavor will stop if the freshly baked coffee beans are put directly into the refrigerator. So if it is just baked coffee beans should be stored in the appropriate environment, wait for two or three days to complete the flavor development, and then put into the refrigerator freezer storage.
