What is exhaust (raising beans) and how does exhaust affect the coffee you make? About 2% of the weight of coffee beans that have just been roasted by fire is carbon dioxide, and this large amount of carbon dioxide emits carbon dioxide with the storage environment, equipment, or method, making the pressure in the package higher than an atmospheric pressure. pressure contributes to the fusion of aromatic substances and oils, making all the aromatic substances inside the coffee beans easy to extract.

The flavor composition of roasted coffee beans has been roughly determined, and many people blame the coffee beans for their deterioration from day to day, but as mentioned earlier, everything will deteriorate slightly after oxidation, affecting the taste. It may not have such a fine taste on the apple, but the coffee will obviously feel the change in taste. On the other hand, the freshly roasted coffee beans release a large amount of aroma factors and carbon dioxide, which are released through small holes through the roasted coffee beans, which are all released during grinding. However, in the process of brewing, the contact between powder and water is eliminated, resulting in insufficient flavor extraction. As time goes on, the atmosphere of carbon dioxide becomes thinner and the contact area increases, and the coffee becomes more and more tasty. Therefore, many people do not call coffee beans as beans, but a process of venting and venting.

With time, the aroma factor is also constantly losing. By that time, the coffee brewed may only have a bitter taste, and all the sour and sweet that you should have have been released by you. According to the roasting degree or the shop owner's suggestion, it is a better choice to raise coffee beans. In addition, it is also recommended that coffee beans can be shaken so that the coffee beans below can also get some air at the top.

At the moment the coffee beans are roasted, he begins to count down his taste period. after the coffee breeding period, there are about two weeks to drink, just like the coffee hunter service is two weeks. During the best taste period, it is possible to cause coffee beans to produce oil, which is in fact normal, but it is also a small warning that the flavor of coffee beans is about to go downhill, reminding you that you need to finish cooking as soon as possible. so that delicious coffee beans won't be wasted!
