Do you want to keep coffee beans? What is the period of raising beans? How long is the bean cultivation period?

I believe that when you buy coffee beans, you will more or less hear the barista suggest that coffee beans that are too fresh (freshly roasted) should be raised before drinking, and the flavor will be better. So, do you want to raise coffee beans in the end? if so, how long will it take to keep fresh coffee beans? today, Qianjie will tell you a little bit about growing beans.

Do you want to keep fresh coffee beans?

The answer is: yes. Freshly baked coffee beans actually have the aroma of popcorn produced by Maillard reaction, with a slightly smoky smell. If you grind and brew immediately, this "unpleasant" flavor will be brought to the coffee. And the freshly baked coffee beans, which contain a lot of carbon dioxide, will act as a barrier to hinder the extraction of coffee flavor substances by water, resulting in insufficient or uneven extraction, resulting in poor display of coffee flavor.

At the same time, we will recommend drinking coffee beans as soon as they are received. Why?

The aroma of freshly roasted coffee can be maintained for two to three weeks, especially at 8-25 days, the aroma is the best and the flavor is the strongest.

The purpose of growing beans is to let coffee beans slowly discharge carbon dioxide and take away the unpleasant smell produced during roasting. At the same time, the specific flavor of coffee will also be released slowly, and the length of time is not fixed. Therefore, the length of time of growing beans is unstable. After receiving the beans, you start to drink, you can slowly feel the subtle changes in its flavor every day, in order to really understand the difference between well-fed beans and not enough beans.

There is no way to taste and judge whether there is enough before brewing coffee, so what should we rely on to know the state of beans?

In fact, at this time, we can simply judge whether the beans are sufficient with the help of the state of steaming and steaming during cooking. The purpose of steaming is to remove carbon dioxide from coffee powder and infiltrate coffee powder so that we can extract it better. When steaming, coffee powder is more likely to have "hamburger"-shaped drum bags, which means that there is more carbon dioxide in the powder and the beans are fresh; if the powder bed changes little and does not bulge too much when steaming, it means that the beans may not be very fresh.

(both coffee beans are 90+eleta, and the cooking date is July 9.)

Of course, the steaming drum bag can only roughly help us to observe the state of the beans, and eventually we have to taste the specific flavor before we can really judge whether the beans are enough.

At present, there is also a technology to add nitrogen to prolong the fresh-keeping time, which can maintain the release of coffee flavor substances to a certain extent. This technology is the earliest to solve the problem of bean preservation in response to ocean transportation. And now the rise of boutique freshly baked coffee, instead of emphasizing how to keep it fresh, it is better to buy fresh, short-term small amounts of beans and drink them as soon as possible, so that you can better appreciate the flavor of the coffee.
