Some friends wrote to ask if you can keep the coffee beans "fresh" by freezing or refrigerating them.

Come True Coffee to answer for you ~

The coffee is still emitting gas after it is roasted. When the beans are frozen / refrigerated, apart from blocking the exhaust of the beans, the water in the beans will also be drained. When taken out, the beans will re-expand at room temperature and absorb the moisture that is not roasted by the beans themselves. At this time, in addition to losing most of the aroma of the beans, the coffee will also be affected by the moisture.

Please do not put coffee beans in cold storage!

Fresh coffee, that is, within three days to six months after roasting, the natural emission of gas at room temperature is completed to achieve the ultimate flavor.

Opaque sealed cans are the best material for storing coffee beans, but the air in the refrigerator is airtight and airtight. No matter how you guard against it, you can't keep coffee beans from absorbing the taste of food in other refrigerators (there may be fish / meat / vegetables in the refrigerator). The jar after taking out the refrigerator will be affected by moisture both inside and outside. Even if you wait until the room temperature is the same before opening it, the coffee beans will lose their freshness because the temperature is higher or lower. The aroma is thus worn out.

When brewing coffee, it is best to grind it and keep it cool and dry at room temperature in order to taste the purest primitive extreme flavor of coffee beans.

Coffee beans and general food, pay attention to fresh, the more fresh, the more you can taste the original taste of coffee beans, but also the best flavor. The taste period of coffee beans is after baking, after 3-7 days, it is best not to exceed a month, because after a month, the flavor of coffee beans will lose quickly and you will not be able to taste the best taste. So, what is the best storage condition for coffee beans? Cut off oxygen (air), dry, dark and tasteless places. Among them, isolating oxygen is the most difficult, although vacuum packaging or sealed packaging is used, it does not mean that it can keep fresh, because coffee is different from ordinary food, coffee beans will continue to release carbon dioxide after roasting, which is easy to cause vacuum packaging to burst. However, sealed packaging can only prevent air from entering, the air originally in the air can not be discharged, the air also contains a little oxygen, so it can not achieve the effect of anticorrosion. The method and importance of coffee bean preservation!

At present, the best preservation package is the "one-way breathable valve". Through the one-way breathable valve, there is only no gas in the bag, and there will be less and less oxygen in the bag, which is exactly what we like to see. In addition, special attention should be paid to the fact that the packaging with an one-way breathable valve must be sealed, and the less air in the bag, the better. The method and importance of coffee bean preservation!

If you can't finish it within the time limit, there is another way to preserve it: use a sealed freezer bag, separate it in a small bag, and put it in the freezer. When you want to use it, take it out and deice it, and then unseal it at room temperature. In this way, it is not easy to have water droplets on the surface of coffee beans, because water is also one of the factors that affect the flavor of coffee, and coffee beans that have been taken out of the freezer should not be put in the refrigerator to avoid moisture affecting the taste of coffee during freezing and thawing. In good storage, coffee beans can be kept in the freezer for up to two months, but it is not recommended. The method and importance of coffee bean preservation!

So can the coffee beans be refrigerated? Coffee beans cannot be kept in the freezer because they can only be kept fresh in the freezer.

There are two reasons:

1. The temperature is not low enough.

two。 Coffee itself has the effect of removing odor, and if it is not sealed, it will easily absorb the taste of other foods in the refrigerator, and the final brewed coffee will become mixed.

After discussing so many ways to preserve coffee, it is best to taste it fresh, so that you can not only enjoy the best flavor of coffee, but also live up to the value of good beans.
