The front street has come into contact with many customers who buy coffee beans, and their requirements for coffee beans are not only the flavor they want, but also fresh, preferably freshly roasted coffee beans. This is the difference between coffee and ordinary agricultural products, because ordinary vegetables or fruits are of course the most delicious when they are first picked, but coffee is different.

Generally speaking, freshly baked coffee beans are not suitable for brewing. Qianjie Coffee generally advises people to grow beans first, and it is most appropriate to taste these beans for two or three days. In fact, raising beans is not so mysterious. Biologically, it is a process of gas release, which we generally call awakening beans, raising beans or ripening.

Because there is a lot of carbon dioxide in freshly roasted coffee beans, coffee beans are released slowly when they are placed in the air, usually three hours after freshly baked coffee. If you brew the freshly roasted coffee immediately, there is still a lot of carbon dioxide in the body and the coffee beans release a lot of gas when they encounter hot water, hindering the coffee extract, then the flavor of the extracted coffee is not so good. and the taste will be very sharp, and even if you brew it at the right time, there will still be bitterness of over-extraction and obvious acidity.

Of course, the time of growing beans is not certain, because if the time of growing beans is too short, the flavor of the coffee has not yet come out completely, then the flavor of the coffee brewed will be very light, and if the time of growing beans is too long, it will make the coffee beans pass the best taste period. affect the flavor of coffee beans. Therefore, generally different roasting degrees of coffee beans have different cultivation time, and the more obvious the exhaust effect is, the faster the exhaust will reach maturity. The shallower the baking degree, the less obvious the exhaust effect, and the longer the ripening time is. Therefore, Qianjie suggests that when buying beans, you should pay more attention to the coffee beyond the expiration date, and also pay close attention to the roasting date of the coffee, and then ask the barista how long it takes to grow the beans in order to taste the best flavor of this coffee bean.

Growing beans is not troublesome, you just need to put the unopened coffee beans in a cool, dry, light-proof, non-irritating environment, and stick the one-way valve after the bean growing period (with transparent glue). The process of growing beans is important, but it is also important for the preservation of coffee beans, because if the bags that have been opened are not sealed, it is very easy to make coffee beans damp and lose their aroma very quickly. Therefore, Qianjie suggests that you can store it in a sealed jar, preferably in a cool and ventilated place. If there is no sealed jar at home, store the coffee beans in a sealed bag with an one-way exhaust valve. Then put it in a cool and dry place.

Of course, some friends will store the Kaifeng coffee beans in the refrigerator. Qianjie thinks that the coffee beans are adsorptive, and the coffee beans stored in the refrigerator are easy to absorb the taste in the refrigerator, and the moisture in the refrigerator is easy to get into the packaging of the coffee beans, affecting the preservation of the coffee beans.

If you really can't wait to grow beans and want to taste this coffee bean right away, Qianjie will tell you one or two tips. You can leave the ground coffee powder for two or three minutes first. In order to properly reduce the impact of carbon dioxide on the hand flushing process, the coffee powder after grinding increases the contact surface area with the air. The carbon dioxide inside can be discharged from more places, volatilizing faster, volatilizing not only carbon dioxide, but also small molecular gases that affect the flavor of coffee. So this is why coffee needs to be brewed and drunk as soon as possible after grinding.

Or everyone can prolong the steaming time appropriately. Because in the brewing process, there will be a steaming process, in the steaming stage, coffee powder will release carbon dioxide, and prolonging the steaming time can make more gas exhaust. At the beginning of brewing, about twice the amount of water is injected and then wait 30 seconds, a step called "steaming" to properly discharge carbon dioxide so that subsequent water injection can be better contacted and extracted with coffee powder. So you can appropriately lengthen the steaming time, discharge more carbon dioxide, and reduce the effect of carbon dioxide on extraction. Similarly, some coffee beans that have been placed for a long time may need to shorten the steaming time. This may also be the reason why hand-brewed coffee in some cafes is only steamed for 5 seconds.

In addition, the hanging-ear coffee that you buy is already ground into powder, so Qianjie suggests that you finish it as soon as possible within a week, because the flavor of the coffee powder will spread very quickly within a week. then the best taste period for hanging-ear coffee beans becomes very short. So you will find that when brewing coffee, the noodles in the process of steaming coffee are not in the shape of a hamburger, but collapse, which means that the coffee beans may not be so fresh. Because hanging-ear coffee is very convenient and does not need other troublesome steps, so many guests come to Qianjie to buy hanging-ear coffee bags.

Although hanging-ear coffee is very convenient, there are some minor problems that need to be paid attention to. Can hanging-ear coffee be recycled and brewed? In fact, a small packet of hanging-ear coffee generally 10 grams of powder, 10 grams of powder can only be brewed once, when you cycle brewing, you may find that the coffee flavor is still very strong, should still be able to drink. In fact, it is not, because when you brew hanging-ear coffee for a long time, because the longer the coffee is brewed, the more caffeine is released, this is because the coffee has been overextracted, and excessive extraction will release the bitter and astringent taste of the coffee. the flavor of this coffee is basically gone. Therefore, Qianjie generally does not recommend that guests cycle to make the same kind of hanging-ear coffee.

In addition, Qianjie advises that when buying hanging-ear coffee, try not to buy hanging-ear coffee for more than five days, because when the coffee beans are ground into powder, the coffee will soon lose its unique aroma and greatly reduce the flavor of the coffee. Just like the general guests who come to Qianjie coffee to buy coffee beans, we will suggest that the coffee beans had better be freshly ground. However, there are also a large number of guests who do not have a bean grinder at home and will be ground directly into powder in the shop in Qianjie, but Qianjie still advises everyone to finish it in a short period of time.
