For professional baristas, please follow the coffee workshop (Wechat official account cafe_style)
The siphon pot (Siphon), which originated in Germany, is a tool that uses the pressure caused by boiling water to make coffee. The siphon pot is constructed as an upper and lower pot connected by a pipe in the middle, and the lower pot filled with hot water will first be heated by an alcohol lamp or a gas lamp. Because at 1 atmospheric pressure, the volume ratio of 1 gram of liquid water to 1 gram of water vapor is 1100, when the volume of steam in the kettle increases with temperature, the liquid water can be easily pushed through the conduit to the upper pot filled with filter cloth and coffee powder, and the water will continue to be supported by a continuous stream of steam on the pot.
When the heating stops, the air in the lower pot gradually cools and shrinks, while the coffee liquid that has been soaked in hot water in the upper pot will flow back to the lower pot because it has lost the support of steam, and the coffee grounds will be blocked by a filter cloth and left in the upper pot. Finally, remove the upper pot and you can enjoy the coffee in the lower pot.
