Why flannel is different from ordinary hand flushing?

Unlike ordinary hand flushing, flannel does not have the potholes of a filter cup, so why do you need flannel? Perhaps the ingenuity of this is that flannel can be interdependent with the roasting degree of coffee beans. As we all know, Japan does not know when, its fascination with deep-baked beans is almost indescribable, and even has a symbolic meaning that is partial to the traditional culture. Perhaps the Japanese have long known that the oil of coffee is the most wonderful finishing touch, while the oil secretion of deep-baked beans is unattainable for shallow-baked beans.

Grease can make coffee smoother, softer, and even lock the aroma, which may be an irrefutable feature of the preference for deep baking. And flannel, is exactly the best partner for deep baked beans, different from the filter cup, no filter cup, no pit marks, but also makes compensation on the other hand, that is, there is no filter paper. The disadvantage of the filter paper is that it blocks the oil released from most of the coffee powder. to preserve more of the oil in the coffee solution, you must first extract it in the filter cup and have enough fusion to make the oil knead into the coffee liquid. Flannel does not need to pay much attention to this problem, because the material, flannel is naturally easy to make grease pass through and fall into the pot, so flannel is indeed a good choice. In addition, the adjustable angle of flannel is also an important place.
