Coffee utensils introduce what is a filter cup

The main distinction of the filter cup is the filter hole at the bottom of the cup. At present, there are mainly four kinds of filter cups: single hole, double hole, three-hole filter cup and V-type filter cup.

The single-hole filter cup was invented by Mrs. Melitta of Germany and is commonly known as the "Melitta Cup". The single-hole filter cup is mainly used for medium and deep roast coffee such as German roast, while light roast is easier to plug the filter hole.

The three-hole filter cup is not easy to block due to many filter holes. It is suitable for coffee of various roasting degrees, and the concentration can be adjusted as long as the extraction amount is adjusted. The three-hole filter cup is called a "Kalita cup."

Two-hole filter cups are intermediate between single-hole and three-hole filters.

The bottom of the V-shaped filter cup is a big hole, and the filter paper used is also a special conical filter paper, so there will be no trouble of blocking the filter hole. However, due to the fast flow rate, it is easy to cause insufficient extraction, and the requirements for "stewing" are higher. The role of the coffee filter cup groove: The main role of the groove in the filter cup is to allow the filter paper and the filter cup to have a gap between the air to pass through, so that the coffee powder can be fully steamed. If there is no groove, or the filter paper is attached to the filter cup with a very shallow groove, the air can only be discharged from the filter hole at the bottom of the cup after hot water injection, and as a result, a large amount of air that cannot be discharged will be rushed out from the surface of the coffee powder in the state of steaming like a volcanic eruption, and the surface of the powder will open a hole, and cold air will enter, resulting in insufficient steaming.
