There are also many kinds of filter cups needed for hand punching, including single-hole filter cups, three-hole filter cups, filter cups with a larger hole in the middle, and so on. If hot water is injected in the same way, the speed of filtration will be different, so the extraction time will also change. The difference in extraction time will lead to a difference in coffee flavor.

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.
