Filter cup type and brand introduction:
·Type
From the quality of material points, filter cups are ceramic, acrylic, AS resin and other types. From the bottom of the filter hole up the number of points, there are single hole, double hole, three holes.
·Brand
The single-hole filter cup was invented by Mrs. Melitta of Germany, so it is also called Melitta cup, which is more popular with Germans who like deep baking. However, the amount of coffee powder and the amount of water injected at the beginning should be calculated well, and the water injection must be completed at one time, so shallow roasted beans that easily block the filter holes are not suitable.
Three-hole filter cups are more common, also known as Kalita cups. Three filter holes allow air and water to pass through easily, suitable for light to deep roast coffee. If the coffee is roasted or ground unevenly, the coffee concentration can be adjusted by adjusting the amount of extraction.
When using filter paper drip method to brew coffee, filter paper will stick to the filter cup wall, if there is no groove, after injecting hot water, air can only be discharged from the filter hole at the bottom of the cup, and the remaining air will be discharged from the coffee powder surface in the steaming state, and the coffee powder surface breaks a hole, cold air enters, coffee will not be fully steamed.
If flannel is used, the air can escape from anywhere, and hot water seeps into the flannel like a film to keep it warm. Therefore, the filter cup must have a deeper groove, so that after hot water is injected into the coffee powder, there is a gap between the filter paper and the filter cup to allow air to escape, so that the coffee can be fully steamed.

To make espresso, you need to match the degree of bean grinding and roasting.
To make espresso, you need to match the degree of baking of bean grinders. Let me tell you the importance of these data. Whenever we adjust the coarseness of the bean grinder to + /-1 scale, the extraction time of coffee will change by 4-5 seconds, and the total weight of coffee will have an error of 10g. Since we are using a large bean grinder, the above changes may not be found on a small bean mill.
