Methods and principles of four kinds of Coffee blending

Siphon brewing method: using the principle of steam pressure (this is a method invented by an ocean engineer, probably inspired by the steam engine), so that the heated water, from the beaker below, through the siphon and filter cloth upward flow, and then mixed with the coffee powder in the cup above, and the coffee powder ingredients are completely quenched out, after quenching coffee, after removing the fire source, flow back to the next cup again. With the scientific process, you can enjoy the fruits of science. If you want to be a scientist, start here!

Filter paper brewing method: this is a housewife invented method, typical household method, much more practical! During brewing, filter all coffee grounds with filter paper, which is discarded every time it is used up, to obtain clear and mellow coffee. When using filter paper coffee pot, it is advisable to select finely ground coffee powder for the best brewing effect.

Filter cloth brewing method: using the principle of "old soup boil new medicine", this is the brewing method favored by insiders, because after repeated use of the flannel used for filtration, the oil of coffee will adhere to the lines of flannel, making coffee more fragrant. If you want to fill everyone's coffee cups in the house at once, try this old cloth----twice the effort!

Droplet brewing method: Droplet coffee, also known as Dutch coffee, brewing with a drip pot is an archbishop of Paris invented. It uses cold or ice water to quench, allowing water to quench coffee essence drop by drop at a rate of 40 drops per minute. (Only a bishop who has nothing to do all day would come up with such a tormenting idea!) If you spare no time and effort, tryit, no one will stop you! It is worth mentioning that this coffee contains extremely low caffeine, so it is particularly refreshing, but the price is extremely high.
