Brand name

The single-hole filter cup was invented by Mrs. Melitta in Germany, so it is also known as the Melitta cup. It is more popular with Germans who like deep baking. However, at the beginning, the amount of coffee powder and the amount of water injected must be calculated, and the water injection must be completed at once, so shallow baked beans which are easy to block the filter pores are not suitable.

Single-hole filter cup is more common, the filter hole allows air, water to pass through easily, suitable for coffee baked at different levels from shallowness to depth. And if the roasting or grinding degree of coffee is uneven, the coffee concentration can be adjusted by adjusting the amount of extraction.

When using the filter paper dripping method to brew coffee, the filter paper will stick to the wall of the filter cup. If there is no groove, after injecting hot water, the air can only be discharged from the filter hole at the bottom of the cup, and the remaining air will be discharged from the surface of the coffee powder in the steaming state. The coffee powder surface will break a hole, and the cold air will enter, so that the coffee will not be fully steamed.

If the coffee is leaked with flannel, the air can be discharged from anywhere, and the hot water seeps into the flannel cloth to keep warm like a skin film. Therefore, the filter cup must have a deeper groove, so that after the hot water is injected into the coffee powder, there is a gap between the filter paper and the filter cup to let the air out, so that the coffee can be fully steamed.
