Qianjie-brief introduction of Coffee and beans

To put it bluntly, bean cultivation is a process of "gas release", which is also commonly known as awakening, raising or ripening.

Because about 2% of the weight of coffee beans that have just been roasted by fire is carbon dioxide, and this large amount of carbon dioxide emits carbon dioxide with the storage environment, equipment, or method, making the pressure in the package higher than an atmospheric pressure. the pressure helps to integrate the aromatic substances with the oil, making all the aromatic substances inside the coffee beans easy to extract.

In general, the exhaust effect of coffee beans does not begin until 3 hours after baking, and the coffee beans do not release any carbon dioxide, and the taste after cooking is very unstable. If you have ever washed hot water into freshly baked and ground coffee powder, or use it to make a cup of Espresso, you will find it very sharp and irritating in taste, with over-extracted bitterness and obvious acidity. It will be difficult for you to associate it with the smooth and sweet taste.

What's the use of growing beans?

Although the flavor composition of roasted coffee beans has been roughly determined, many people blame coffee beans for the change in flavor from day to day. In fact, everything will deteriorate slightly after oxidation, affecting the taste, may not have such a fine taste feeling on the fruit, but the coffee will obviously feel the change in taste.

Do not think that the cultivation of beans is not important, the coffee with bad beans has a dirty taste, the editor has deep experience! First of all, insufficient coffee beans will have a "dry" feeling, which is the residual smoke smell of coffee beans after being roasted at high temperature, which needs to be removed after a period of ripening and carbon dioxide emissions, so let it stay for a few days during the bean cultivation period. you will find that the taste is clean and the flavor highlights ~

How to raise beans? How long will it take?

Having said so much, how on earth should we raise it? I wonder if all of you have noticed that there is a round one with several holes on top of the bag of ripe coffee beans. We usually call this thing a "one-way exhaust valve". The best way to keep beans is to put it in a bag with an one-way exhaust valve. Place the unopened coffee beans in a cool, dry, light-proof, non-irritating environment. Stick the one-way exhaust valve after the bean cultivation period (with transparent glue).

As for how long the bean cultivation period is? It is best to ask the merchant, because each baker's baking method is different, the baking depth is different, and the damage to the structure of coffee beans is also different, so there is no standard answer for bean cultivation time. However, we can determine the time to grow the beans mainly according to the roasting degree of the coffee beans.

Generally speaking, medium-and deep-roasted coffee takes less time to grow beans than light-roasted coffee, and the normal figure is about 3 days. Of course, there is also the saying that you don't have to raise it and rush it directly, because there will be great differences in different methods. Maybe the coffee beans baked by this baker have a higher ripening ratio than others, so you don't have to raise them.

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!
