Drinking coffee is about freshness, and if the coffee beans are not preserved properly, it will accelerate the aroma loss of coffee beans, thus affecting the taste of coffee, so the preservation of coffee beans is a key point.

Roasted coffee beans are easily oxidized by oxygen in the air, which deteriorates the quality of the oil, volatilizes and disappears, and then deteriorates quickly through temperature, humidity, sunlight and so on.

Therefore, the preservation of coffee beans is usually required to be airtight, low temperature and avoid light.

Can coffee beans be kept in the refrigerator?

Although it is said that unopened coffee beans can be put in the refrigerator, the temperature decreases, the oxidation rate of coffee beans will become slower.

However, if the coffee beans have been opened, it is not recommended to put them in the refrigerator. Among the important elements that affect coffee, moisture has the greatest impact on the taste of coffee. Coffee beans will absorb moisture and the taste will deteriorate to a large extent.

The suggestion for the preservation of coffee beans after opening is to put the coffee beans in a special sealed can or use a special sealing strip (clip) and store them in a cool and dry place after sealing.

Qianjie coffee suggest how to store coffee beans?

1. Keep it at room temperature:

Microbes and oxidation are carried out at an appropriate rate at room temperature, and freshly roasted coffee beans can be kept for two weeks at room temperature. The change in the taste of coffee in the past two weeks is worth pondering.

Just baked the first day, its taste is not very mature, you will smell the grass. On the other hand, the charming sweetness of coffee beans is not strong enough, and you will feel that its taste is "stuffy". In the next few days, the smell of grass will slowly decrease, while the sweet smell will slowly rise. The sweet smell reached its peak on about the third day, and then slowly faded.

On the whole, the personality of the coffee bean will be obvious and active in the first few days, and its personality will become docile after about a week. Some people insist on tasting the personality of coffee a few days ago, while others like to taste the gentle side of coffee beans at room temperature for a week. If you can finish your coffee beans within two weeks of baking, it is recommended that you keep them at room temperature so that the same bag of beans can feel its variety.

two。 Put in the freezer:

Putting in the freezer can make the oxidation process very slow and has the effect of dehumidification. If you buy coffee and drink it for a long time, use this method.

It is recommended that coffee beans be put in the freezer when the reaction is most active in the first three days, because the flavor slowly increases and changes in the first three days.

There are several points that need to be paid attention to in freezer storage:

a. When the beans are taken out and come into contact with the hot and humid air outside the beans, the water will condense on the coffee beans to speed up the deterioration of the coffee beans, so it is recommended to put them in the freezer after sub-packing.

b. Pay attention to whether there is a strange smell in the freezer. Coffee beans are very tasty. So if you can put it in the freezer, you can consider using a small fresh-keeping box to put it in.

3. Refrigerate:

The condition of cold storage is similar to that of freezer, except that the temperature is higher than freezing, so you can still play with the change of coffee beans. Refrigerating is also a good solution when the room temperature is too high or the climate is too wet.

4. It is best to preserve ground coffee in the form of coffee beans, because the area of reaction with air is much larger, so it changes very quickly, and the relative preservation time is not long.

So it's best to have your own bean grinder and grind the beans before cooking.

The preservation of coffee beans is not very absolute.

Coffee beans will oxidize, so temperature, humidity and oxygen content are the main factors that affect the changes of coffee beans. As long as you grasp these key points, you can make use of suitable preservation methods as needed.

If you want to keep your coffee for a long time, you'd better put them in a sealed bag and put them in the freezer. Roasted coffee beans should be prepared in the same way if they are to be preserved for more than a week. You don't have to thaw when grinding-you can put them directly into the grinder.

Another enemy of coffee beans is oxygen, which oxidizes volatile odors. That's why you grind the coffee before you make it. When the coffee bean is ground, most of its surface is exposed to the air. This means that the coffee oil will begin to evaporate and the taste will gradually disappear into the thin air.
