Siphon coffee extraction requires skill and experience. Professional baristas cook siphon coffee with different stirring or water treatment techniques depending on climate, humidity, room temperature, bean seed and roasting degree.

Every time you use a siphon coffee pot, it's like doing an experiment. It's dangerous to some extent and discourages people. But the principle behind a siphon coffee pot is very simple. Siphon coffee pot is divided into upper pot and lower pot. The upper pot will have a pipe connected to the lower pot. The middle of the upper pot and the lower pot will be separated by a filter screen. The connection position of the upper pot and the lower pot will be sealed, so that air can only enter and exit the lower pot through the pipe of the upper pot. When making coffee, the water is heated in the lower pot and the coffee powder is placed in the upper pot. When the water is heated to boil into steam, the pressure in the lower pot will rise due to the expansion of the gas, forcing the liquid in the lower pot to flow upward through the conduit, and the hot water flowing upward will immediately extract the coffee powder.

After a period of time, when the heating of the lower pot is stopped, the pressure in the lower pot will drop, and the coffee extract will flow through the filter to form siphoning coffee. It is worth noting that although it is named Siphon Coffee, it is actually not applied to the siphon principle. It's about expansion and contraction.
