The Spring Festival is approaching, and it is another special Spring Festival. Many express delivery services have been suspended one after another. Smart friends have already prepared surplus food for the winter and filled their coffee cabinets.
However, there is still half a month before the Chinese New Year, and how to preserve coffee beans has become a big problem for friends.
There are three taboos when storing coffee beans: high temperature, moisture, and oxidation.
Coffee beans evaporate aroma substances very quickly when the room temperature is higher than normal, and when exposed to sunlight, it is easy to breed fungi and bacteria, leading to deterioration.
Lingnan people have a deep understanding of humidity. It is common for indoors to become damp and moldy. The same is true for coffee beans. When damp, they are prone to moldy and spoilage.
Oxidation is a reaction that occurs when food comes into full contact with oxygen. Peeled apples and potatoes are more common and will turn reddish-brown after being exposed to outside air for a period of time. The oxidation reaction of coffee beans is not as obvious as these, but with continuous exposure to oxygen, the tasting period of coffee beans will be greatly shortened.
Therefore, Front Street usually recommends that after receiving the goods, keep the original packaging intact in a cool and dry place, and then pick up another package when you need to use it.
Q: Is it best to open the bag immediately after receiving the coffee beans and store them in a sealed jar?
If the coffee beans have been opened, it is best to store them in a sealed jar to preserve the flavor of the coffee beans as much as possible. But if it is not opened, it is best to place it in the original package in a cool and dry place. The coffee packaging bag is equipped with a one-way exhaust valve so that the pressure can be released when the air pressure inside is too high, while the sealed can does not have this function. And when the coffee beans are put into the jar, the process itself has been deflated and exposed to the air, which seems to be unnecessary.
When drinking, open the bag and store it in a sealed jar.
Q: Is it best to store it in the refrigerator or freeze it?
Front Street has also seen many bean storage strategies. Storing them in the refrigerator can effectively reduce the oxidation reaction of coffee beans. Front Street has also conducted corresponding experiments, placing fresh-keeping layers at 5-15 degrees Celsius and refrigeration layers at -20 degrees Celsius. It is undeniable that low-temperature storage does effectively slow down the oxidation of coffee to achieve a longer tasting time.
However, the requirements to achieve this effect are quite demanding. I believe that the refrigerator at home is not just for storing coffee beans. Fruits, leftovers, and beverages are all frequent visitors to the refrigerator. In such a complicated process, odors are inevitable. The coffee beans will "ruin" the coffee by absorbing the odors in the refrigerator.
Then there is the problem of thawing. In the fresh-keeping layer, the temperature of the coffee is not that ridiculously low, but if it is taken out immediately to grind and brew, the brewing process will generally be lower than that stored at room temperature, so the brewed coffee will not have enough flavor.
Coffee taken out of the refrigerator needs to be thawed. Thawing will inevitably produce water vapor. This water vapor is formed by condensation of water vapor in the air, which means it is very susceptible to moisture.
If you can simply solve the problem raised by the front street, refrigerated storage is also a good choice.
This kind of protection is more comprehensive. If you don’t have the conditions, you should not put it in the refrigerator.
Therefore, friends who are stocking up for the New Year should just follow the storage principles of dark, dry and sealed coffee beans.
