There are four main factors affecting the freshness of coffee beans: air, humidity, sunlight and temperature. Compared with the dry and cool continental climate in Europe and the United States, Taiwan is often humid and hot, which is really a challenge to the preservation of coffee beans and requires more attention and care. When coffee beans come into contact with oxygen in the air, it will greatly accelerate the aging of coffee beans. High humidity is also a challenge for the storage of coffee beans, so coffee beans are not suitable for storage in the refrigerator or freezer, because once moved from a low temperature space to a high temperature, the coffee bean meter will begin to produce moisture, making the quality of the coffee worse. Direct sunlight is also one of the killers of coffee beans, so if coffee beans are stored in transparent sealed cans, please remember to put them in cabinets where the sun is out of reach. Coffee beans should not be exposed to high temperature before brewing, because the high temperature will cause the coffee to emit aromatic molecules, and in a few days your coffee will lose most of its aroma and will no longer be attractive. To sum up, coffee beans should be stored in a sealed bag with an one-way exhaust valve, dry, dark and cool to slow down the aging of coffee beans.

Preservation of coffee beans

There is no special way to preserve coffee beans, which is known to many people as sealed preservation.

If you have a choice, glass will be better than plastic containers. It is best to store coffee separately according to the type of coffee, even if the taste of coffee is similar, try not to put it in the same plastic container, because this will make the original aroma of coffee mixed together, and then it will be very difficult to make coffee with the original flavor.

On the contrary, there is no gas leakage from the glass container, so even if different kinds of coffee are put together, as long as they are arranged in order, the coffee beans can be well washed before use, and the original flavor can still be preserved. In addition, when saving the coffee, put the whole bag of coffee into the container together, so that the next time you want to change the coffee, it is very convenient to replace it.

Finally, it should be noted that there is no problem with the sealing function of containers, because there are many products on the market that claim to be sealed containers, but in fact some of them do not have the sealing function.

Many coffee lovers like to buy beans from their own bakery, but it feels professional to see the sacks all over the shop. In fact, the quality of raw coffee beans has been paid attention to in recent years, and because the coffee beans contain ochratoxin in the past, people began to have the important concept of preserving raw beans. Of course, some stores think that large sales do not need to be equipped with constant temperature wet boxes, but even if there is no production of raw beans, the water content of raw beans will also change, and the aroma of roasting at high temperature will be greatly weakened. Of course, it is also freshly baked!
