Siphon pot + mocha pot

[how siphon pots and mocha pots work] are actually similar: the water in the lower kettle is heated and sealed, and the water vapor produced by boiling forms air pressure, which is extracted by pressing the water into the upper pot through a tube. The difference is that the mocha pot is more airtight, the coffee powder is ground finer and pressed into pressed powder, high-pressure hot water passes through pressed powder quickly, and the coffee liquid extracted from the siphon pot is stronger, while the coffee liquid brewed in the siphon pot will eventually be sucked back into the next pot by cooling air pressure.
