"Coffee needs beans! It didn't taste good in the first three days after the fresh baking was finished! " Do you always hear that coffee friends often talk about coffee raising beans / waking beans? Coffee beans are not red wine, why do you have to put them for a while before they taste good? In this article, Qianjie Coffee will talk to you about the importance of freshly roasted coffee and beans!

What is coffee and beans?

Coffee beans produce a lot of carbon dioxide in the roasting process, and when the coffee beans come out of the oven, they absorb a large amount of carbon dioxide into the body of the coffee beans, standing at 2% of the weight of the coffee beans. If there is too much carbon dioxide in coffee beans, there will be a lot of bubbles after contact with water in the process of extraction, which will change the flow channel of coffee powder layer, affect the stability of coffee extraction, and finally greatly affect the flavor and taste of coffee.

Do I have to raise beans?

Most coffee beans are not in the best state when they are roasted, and they usually have an obvious sense of dryness and choking, and the taste is more sharp and irritating. Therefore, freshly roasted coffee beans need to be placed in the original package with a single exhaust valve and in a dry and cool place for 3-7 days, allowing the coffee beans to release some carbon dioxide and take away the feeling of smoke.

Time for coffee and beans

This needs to pay attention to the coffee roasting date and coffee roasting degree to determine. Qianjie Coffee all the coffee beans shipped within 5 days after the roasting is completed. After receiving the coffee beans, you can look at the baking date on the back label on the package and the time for sour beans from the roasting date.

At present, the roasting degree of Qianjie coffee is divided into three kinds: the recommended cultivation time of medium and shallow roasted coffee beans is 3-4 days; the recommended baking time of medium-roasted coffee beans is 4-5 days; and the recommended baking time of medium-deep roasting degree is 6-7 days.

After raising the coffee beans, the extraction will become more stable, and the taste will be fuller and cleaner. If the room temperature is low in winter, the bean raising period can be appropriately prolonged for 2-3 days.

How to tell if the coffee beans are ready?

The judgment of hand brewing will be very intuitive ~ according to the daily brewing of Qianjie coffee, it is noted that if there is still a large amount of carbon dioxide in the coffee bean, there is still an obvious atmospheric bubble after wetting the powder layer evenly for 30 seconds in the steaming stage, and the coffee beans can be kept for 1-2 days.

Italian extraction judgment, we need to pay attention to the performance of espresso oil after the completion of extraction. If the fat is too rich / the greasy noodles are too thick, the coffee taste is that the beans show a sense of smoke / dryness. All these show that the content of carbon dioxide in coffee beans is relatively high, so you can try the follow-up performance after putting it properly for 2-3 days.
