Type and characteristics of hand-brewed coffee filter cup selection of coffee utensils what brand of individual coffee is there in the hand brewer?
The speed of filtration changes because of the area of the hole on the filter cup, the smaller the area, the slower the filtration speed, this type of filter cup because the injected hot water will first stay in the filter cup, and then filter at a certain speed, extraction occurs in stagnant hot water, so the injection mode of hot water will not be affected, and can make relatively stable coffee.
The larger the pore area, such as a three-hole filter cup and a large-hole filter cup, the faster the filtration speed will also affect the way of injecting hot water. Hot water injection into these filter cups will not stagnate. Generally, the injection position is in the center, while the extraction is filtered at the same time. If you constantly change the position of hot water injection, the flavor of coffee will be easier to extract, but if the injection position remains unchanged, it may lead to uneven extraction. The flavor is not complete.
When selecting the filter cup, we should pay attention to the material of the filter cup. If it is a ceramic filter cup, the shape of each will be different. If the groove on the inside of the filter cup is too shallow, the hot water is not easy to pass through, which will cause excessive extraction.
When buying filter paper, we should pay attention to that the taste of some filter paper is very obvious, which will affect the aroma of coffee. We must choose filter paper that has no flavor and moisten the filter paper before brewing coffee. It can also eliminate the smell to a certain extent.

First, when the preheating temperature of the oven is not enough, the coffee beans are immediately put into the oven, which prolongs the baking time. Therefore, the baking loss is large, and the color of coffee beans is light, which is due to the lack of heat and the lack of full coking of the skin, resulting in a lack of color and rough internal tissue. Second, the temperature of the oven is too high, the surface of coffee forms hard skin prematurely, which suppresses the expansion of internal tissue, and because of its surface.
