Qianjie-brief introduction of Coffee Bean

1. What is raising beans?

Bean cultivation means that cooked beans are roasted and stored in sealed coffee bags to release carbon dioxide and some other gases from the roasting process, and stabilize the various substances inside the beans through several days of rest.

And the coffee bean bags where we store coffee have an one-way exhaust valve. The function of the one-way exhaust valve is to remove the gas from the bean bag, but it can prevent the air from outside the bean bag from entering the bean bag. The advantage is that contact with air can be avoided before opening, and all bean bags are basically protected from light.

Now someone is going to ask. Why are beans stored in transparent jars in some cafes? Uh, because they have already passed the bean cultivation period, at this time, the barista does not want the coffee beans to exhaust again, because regardless of the bean cultivation period or the taste period, coffee beans always release their own aromatic substances into the air, but it is a pity that baristas do not have magic and cannot use a vacuum, so they can only be stored in sealed cans to reduce the loss of aromatic substances as little as possible, and the position of the sealed cans must be protected from light.

Some bakers take a cup test after baking, so there is no need to raise beans. They may test the cup as soon as the baking is over or wait for a day's cup test. Because the cup test method is special, this way will show all the good side and bad side of coffee, so it is similar to the existence of a demon mirror and does not care whether it has ever raised beans or not.

And other extraction methods can be different, hand flushing, siphon, French pressure kettle, love pressure all attach great importance to the cultivation of beans.

Among them, the extraction method that has the greatest influence on whether to raise beans or not is the Italian coffee machine. The fresh coffee beans are more difficult to extract, because there is too much carbon dioxide, which hinders the extraction of coffee powder by water.

Just baked without beans, drink compared to beans will be a little more exciting, the flavor is not so obvious, the whole will not be too round

OK, as I just said, coffee beans always release their aromatic substances into the air, so there is a time limit for the taste of coffee beans. As far as I understand it, the duration of individual coffee is 20-30 days, and that of espresso is 30 days.

And the coffee and bean cultivation period is about a few days.

It takes 3-4 days for each product to bake and raise beans.

The time for deep baking and raising beans per product is 4-7 days.

It takes 15-21 days for espresso to grow beans.

Knowledge: generally speaking, bean cultivation is mainly aimed at Italian extraction, the opponent does not have too many requirements, only 3-4 days on it.

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.
