Methods and principles of four kinds of Coffee blending

Siphon brewing: using the principle of steam pressure (a method invented by a marine engineer, probably inspired by a steam engine), the heated water flows upward from the lower beaker through a siphon and filter cloth, and then mixed with the coffee powder in the upper cup, the ingredients in the coffee powder are completely quenched out, and the quenched coffee liquid is removed from the fire and flowed back to the lower cup. After full of scientific process, you can enjoy the fruits of science. If you want to be a scientist, start from here!

Filter paper brewing method: this is a method invented by housewives, a typical family method, much more practical! In brewing, filter paper is used to filter out all coffee grounds, and the filter paper is discarded every time it is used to get clear and mellow coffee. When using filter paper coffee pot, it is appropriate to choose finely ground coffee powder to get the best brewing effect.

Filter cloth brewing method: using the principle of "old soup boiling new medicine", this is the brewing method favored by experts, because after the filtering flannelette has been used repeatedly, the fat of the coffee will be attached to the lines of the flannelette, making the coffee more mellow. If you want to fill everyone's coffee cups at once, try this old cloth-get twice the result with half the effort!

Drip brewing: dripping coffee, also known as Dutch coffee, is a dripping pot invented by an archbishop in Paris. It uses cold or ice water to quench the coffee essence at a rate of 40 drops per minute. Only the Bishop, who has nothing to do all day, can come up with this grinding idea! If you spare no time or effort, tryit, no one will stop you! It is worth mentioning that this kind of coffee contains very low caffeine, so it is very refreshing, but the price is very high.
