"freshly roasted coffee beans need to be nourished / awakened before they taste good."raise beans and wake up beans, I believe we are no stranger to these two words. But coffee beans are not red wine! In this article, we will follow Qianjie Coffee to find out why coffee beans should be raised and awakened.

In the final analysis, raising beans and awakening beans are the process of releasing carbon dioxide, and carbon dioxide will affect the stability of coffee extraction and the extraction of flavor components in coffee.

During the roasting process of coffee beans, with the increase of heating time, the structure of coffee beans will further change and release a large amount of carbon dioxide. When the coffee bean comes out of the oven, the hot expansion and cold shrinkage will cause the coffee bean to contract instantly, "absorb" a lot of carbon dioxide and then "lock" it in the body, and release it at a very slow rate after it comes out of the oven.

The advantage of the existence of these carbon dioxide is that it can help to retain the flavor and aroma of coffee, but the disadvantage is that too much carbon dioxide will affect the stability of coffee extraction. So freshly roasted coffee beans can not be in a hurry to drink, let the coffee beans in the original package with a single exhaust valve sealed for a few days, let the beans release carbon dioxide on their own, and through the single exhaust valve (only out, not in).

The bean-raising / awakening period of each packet of coffee beans is different, and the bean-raising time will be different with different baking degree. Qianjie Coffee currently has three roasting levels on the shelves: medium-light (milk chocolate), medium (cinnamon) and medium-deep (dark chocolate).

The deeper the roasting, the more carbon dioxide in the coffee beans. Therefore, Qianjie Coffee recommends that the raising time of shallow roasted coffee beans is 3-4 days, the medium roasting degree is 4-5 days, and the medium-deep roasting degree is 6-7 days.

All coffee beans sold in Qianjie Coffee are shipped within 5 days after roasting. After receiving the coffee beans, you can pay attention to the baking date marked on the back of the package, and then decide whether you need to raise beans ~ the coffee beans can be preserved in the original package, or you can choose a sealed jar to avoid light.

Now someone is going to ask. Why are beans stored in transparent jars in some cafes? This is because baristas want to show coffee beans more like guests, but high sunlight or lights can also accelerate the dissipation of coffee beans. If the coffee beans are not brewed and drunk quickly, Qianjie coffee is recommended to be preserved in a sealed hall away from light. If you use a transparent sealed tube, remember to store it in a cool and dry place.

Although the shelf life of coffee beans after roasting is 1 year, the aroma substances in coffee will gradually dissipate with the increase of baking time. Therefore, the best taste period of freshly roasted coffee beans is within 30 days after the date of cultivation.
