Guide reading

The barista in front of the street will tell the customers who come to the store to buy coffee, "this bag of coffee has been freshly roasted in the last two days. I suggest you keep it for another two days and then open the bag to taste it!" Many friends have little knowledge of bean cultivation. In this issue, baristas will share why coffee beans need to be grown.

Why do you need beans?

Because about 2% of the weight of coffee beans after roasting is carbon dioxide, and this large amount of carbon dioxide will continue to be emitted. When the gas in the coffee bean is too exuberant, that is, the freshness is very high, it will take a period of time to let some of the gas out of the body to stabilize the coffee bean.

Too much gas is not a good thing, because when brewing by hand, the exuberant gas will continue to be discharged after the coffee powder is exposed to water, disturbing the powder layer, and too much coffee gas will also inhibit the release of coffee flavor and increase the difficulty of brewing. Coffee beans without gas is not a good thing, this is not fresh performance, without the inhibition of gas, coffee flavor is more likely to dissipate.

How long does it take to raise beans?

For coffee beans baked in the former street, for example, each bag of coffee beans in the front street is marked with a baking date. Generally, it takes about 4-7 days for medium-to-shallow roasted hand-made coffee beans, about 7 days for medium-and deep-roasted hand-roasted coffee beans, and about 10 days for Italian coffee beans. Of course, because the baking styles of each family are different, the duration of raising beans will also be different.

What happens if you drink directly without raising beans?

Under-nourished coffee beans will have a "dry" feeling, which is the choking smell of smoke left inside coffee beans after being roasted at high temperature, which takes a period of time to release carbon dioxide to remove, so coffee grown for a few days tastes cleaner than coffee without beans. The flavor highlights.

How to grow coffee beans?

In fact, the coffee beans do not need to do much, do not need to open bags to put sealed cans, do not need to put refrigerated. As long as the original package is placed in a cool and dry place, the coffee bag will be equipped with an one-way exhaust valve. When the coffee bean emits gas, the bag will be bulged. The function of the exhaust valve is to prevent the coffee bag from breaking and maintain the pressure balance between the inside and the outside. Then you can open the seal and taste it after the suggested bean growing period.
