The basic common sense of boutique baristas makes the taste of beans more stable.

Andrea Illy has done a lot of scientific research on coffee packaging and quality maintenance. He believes that fried coffee needs to be aging in a monitored environment before being packaged. Because the taste of cooked coffee beans is more stable. However, he also made it clear that the definition of aging and stale is very vague. The author believes that this is the blind spot of the concept of "raising beans". The so-called bean cultivation is similar to red wine which needs moderate oxidation to become smooth and layered after opening the bottle, but after being kept for a long time, the wine will turn sour again. Freshly fried coffee beans sometimes have grassy (peasy), which will disappear after the next night. On the other hand, new beans have a taste of baked bread, which those who insist on growing beans may not have tasted. In the author's coffee shop, freshly fried beans will be on the shelves after one night. Although the taste will change over time, guests can also see it as an extra journey, witnessing the ups and downs of coffee. Of course, to get rid of the beans that have been fried for two weeks is the basic persistence of being a boutique coffee shop.
