Can coffee beans be kept fresh by putting them in the refrigerator? Can you extend the tasting period?

It is Singles' Day again. I believe many friends have bought a big wave of beans because of the impact of discounts. Because, backstage in the front street, many friends began to ask about the storage of beans! Among them, several similar inquiries attracted the attention of the front street: "is it really useful to put beans in the refrigerator?"

Friends must have seen the way of frozen coffee beans spread on the Internet, so today, Qianjie will discuss with you whether freezing beans in the refrigerator can play the role of "keeping fresh". Beans also need to be "fresh"? Wait a minute, don't get me wrong, the word "fresh-keeping" here does not mean that coffee beans do not go bad as quickly as melons and vegetables. It actually refers to preserving the aromatic substances held by coffee beans, that is, the flavor of coffee!

Because fresh coffee starts on the fourth day after baking and lasts until the 30th day is the best time to enjoy it. During this time, you will taste the fullest flavor of this coffee, that is, its heyday! After 30 days, the flavor will gradually lose, and the coffee beans that can rush out of rich layers will gradually be transformed into water that can only flush out the smell of coffee. Therefore, when friends buy too many beans and cannot drink them all within the appreciation period, they will start to look for ways to keep them fresh, and this freezing is one of the more widespread ways to spread on the Internet. Why do you say that freezing can keep coffee beans fresh? At low temperature, the oxidation and metabolic rate of coffee beans will be greatly reduced, which can delay the loss of coffee bean flavor and increase the time of the best taste period. According to research, frozen coffee beans can extend the best taste period to 2-3 months, during which the beans will be in a "fresh" state.

However, experiments done earlier on the front street have confirmed that the beans, which have been appreciated for a longer period because of freezing, are only in a "pseudo-fresh" state. There is still a slight gap in the flavor of the coffee compared with the state during the appreciation period. The main purpose of the frozen coffee beans that we can often see on the Internet is to make the ground coffee particles more uniform! Why is it said that freezing can grind more uniform particles? The quality of frozen coffee beans will become more crisp than before, and the water and oil contained in the beans are also in a solidified state, so when we grind them at this time, the occurrence rate of fine powder will be greatly reduced. you will get more uniform particles than beans that are not frozen!

But! Yes! Friends are not advised to apply this method to their daily life, because there are many variables and things to consider are more complicated. First, frozen coffee beans need to be ground as soon as possible. first of all, due to the great temperature difference between inside and outside the refrigerator, when we take out the coffee beans, the frozen coffee beans have already begun to thaw and moisture will appear on the surface of the beans in less than a minute.

In other words, if there is no grinding and cooking for more than a minute, when the beans are hydrated due to the temperature difference, it will not only affect the grinding quality, but also cause greater variables during cooking. Moreover, taking beans out of the refrigerator to grind and boil, these things are really in a hurry to start in a minute! Second, the adjustment of brewing parameters is followed by the adjustment of brewing parameters. Low-temperature coffee beans must need to increase the extraction intensity, such as raising the water temperature or fine grinding, otherwise it will be easy to get a pot of coffee with insufficient extraction. That is very different from the starting point! And these are only the brewing problems that need to be solved after freezing, frozen coffee beans, also need to pay attention to a lot!

What do frozen coffee beans need to pay attention to? Frozen coffee beans can not just be thrown into the freezer, we need to seal it, it is best to vacuum it and then store it!

Otherwise, if it is not sealed, all kinds of strange flavors in the refrigerator will pour into the coffee bean bag, and the "breath" of the coffee bean will inhale them all, and then you will get a "refrigerator honey treated" coffee bean! The coffee made by grinding it is bound to have a little "special" flavor!

(the picture shows the wrong way of freezing beans in the refrigerator without taking any measures.) moreover, frozen coffee beans can only be thawed once, and you can't freeze them again when you take them out of the refrigerator. So usually the bosses divide the coffee beans into a portion and freeze them separately. So, how on earth should we preserve the beans? The easiest way is not to hoard beans as much as possible. After all, no matter how they are stored, they don't taste as good as when they are fresh. This is the core idea that Qianjie has adhered to for many years: beans are better than fresh beans. But if you have already bought a lot and have to send it soon, you can move to the article "Storage of Coffee beans" on the front street to find a more appropriate way to store beans and prolong the taste period.
