Illustration: when is your coffee most blooming?

If you draw a life schedule for roasted coffee, then basically after 40 days of coffee, its life is gone, and then you drink, in fact, the dead body of coffee (paste and caffeine). Its soul (all kinds of aromas) is gone.

As a matter of fact, friends who often drink coffee know this, and it is also a clich é when I say it here. In fact, up to now, human beings have not invented how to keep the roasted coffee "always young". Since coffee has been roasted, it has entered a process of rapid aging, that is, the process of oxidation, and sunlight is the catalyst of the oxidation process, which is an inevitable natural phenomenon. You might say that vacuum airtight preservation is not enough. No ~ because the coffee itself releases carbon dioxide after roasting, so it cannot be completely sealed. Usually, the packaging of our coffee is an one-way valve coffee bag, which can release the gas released from the coffee and prevent the entry of oxygen at the same time. In this process, the aroma of coffee will be released slowly, and there is nothing we can do to stop this process. What we can do is to drink the coffee as soon as possible and enjoy its short life.

Many friends, I believe they don't have the patience to finish reading these words, so I don't have a specific description. Maybe you prefer to read a picture by hand, but you still don't use Chinese to mark it after thinking about it for a long time. It seems to be more harmonious in English, . Or I don't look good in Chinese. Fortunately, they are all relatively simple words that everyone should be able to understand.
