Siphon coffee

Siphon originated in Germany, a tool that uses the pressure generated when water boils to cook coffee. The structure of siphon pot is upper pot and lower pot connected by pipe in the middle. The lower pot filled with hot water will be heated by alcohol lamp or gas lamp first. Because the volume ratio of 1 gram of liquid water to 1 gram of water vapor is 1:100 in 1 atmosphere environment, when the volume of water vapor in the lower pot increases with temperature, it can easily push liquid water through pipe to the upper pot filled with filter cloth and coffee powder, and water will be continuously supported by endless water vapor in the upper pot.

When the heating is stopped, the air in the lower pot will gradually cool and contract, and the coffee liquid soaked in hot water in the upper pot will lose the support of the water vapor in the lower pot and flow back to the lower pot. The coffee grounds will be blocked by the filter cloth and stay in the upper pot. Finally, the upper pot can be removed to enjoy the coffee in the lower pot.
