Qianjie-brief introduction of coffee cultivation and appreciation period

The freshly roasted coffee beans are too young, or described as "angry". You need to give the coffee beans some time to reach the most perfect and balanced stage!

Because after roasting, coffee beans will produce a large amount of carbon dioxide and gas, which will affect the contact between coffee powder and water during brewing, resulting in uneven extraction of flavor and aroma substances! In addition to indicating the baking time, you should also indicate the best time to grow beans, but the presence of carbon dioxide in coffee beans is not entirely a bad thing, because carbon dioxide forms a protective layer inside and outside the coffee beans, isolating oxygen, slowing oxidation and keeping coffee beans fresh.

The freshly roasted coffee beans have only aroma and sour taste, and then the sour taste is gradually removed, the taste becomes full, the flavor reaches its peak during the bean cultivation period, the flavor is mellow, and the taste is rich, and then the bitter taste becomes more and more, and the aroma gradually evaporates away, therefore, it is a better habit to wait for a few days after baking before making coffee. The beans must be packed in a package with an one-way breathable valve, and the seal will not discharge carbon dioxide so that the coffee still feels dry during the growing period.

In fact, there is no specific schedule for bean cultivation, because there are too many factors that affect coffee beans, such as roasting degree, preservation method, environment and so on.

The following are the specific suggestions for the cultivation time of coffee beans, which can be distinguished according to the roasting degree of coffee, which can be used as a reference for everyone and cafes!

Very shallow baking: about 4 days shallow baking: about 3 days baking: about 2 days deep baking: no deep baking: no need

But for family customers, the flavor of newly baked beans begins to decline after a month. If there are few selected bad beans, the baking uniformity will be greatly improved and can be withdrawn in about two days, and you can drink it on the third day.

Flavor period (also known as appreciation period) the best time for coffee to taste after roasting. Freshly roasted coffee has a self-fermentation process within a week, making the flavor more perfect, after this stage begins to oxidize and volatilize, and the good coffee flavor begins to lose gradually. Therefore, the best flavor period for coffee is within two weeks after baking, when the coffee will have a very fresh aroma and rich in oil, the coffee with sweetness has an obvious return to sweet taste, and the coffee powder is obviously expanded after being infiltrated by hot water. this is often a simple way to determine whether coffee is freshly roasted.

A large number of practices have proved that the flavor period of coffee cooked beans is basically less than 1 month, and the longest sealed preservation is no more than 2 months. After the coffee is ground into powder, the surface area increases, which accelerates oxidation and volatilization, so the flavor period is shorter, so it is difficult to get the flavor when buying hanging-ear coffee in the supermarket. No matter what brand of coffee, after the flavor period can not be called good coffee, "fresh" is the premise of good coffee.

Knowledge point: the way to reduce exhaust is to increase the time of growing beans, so that the oxidation reaction of coffee beans becomes smooth, and the flavor will become more balanced.

In short: Qianjie is a coffee research hall, happy to share the knowledge about coffee with you, we share unreservedly just to make more friends fall in love with coffee, and there will be three low-discount coffee activities every month. The reason is that Qianjie wants to make more friends drink the best coffee at the lowest price, which has been Qianjie's tenet for 6 years!
