Various utensils and principles for making coffee by brewing technology 2

Filter Coffee: The most popular coffee brewing method for coffee players now, there are numerous ways to play, the general method is to use the coffee powder that has been lightly roasted and coarsely ground into the filter paper (or flannel), slowly inject hot water into the center of the coffee powder to extend around, and then return to the center from the periphery (no matter how much water is injected, it is necessary to be uniform), and then soak the coffee powder in hot water and drop it into the sharing pot to complete the extraction. Each cup of coffee about 8~12 grams of coffee powder, hot water 85-95℃ hot water.

■ Moka Maker: It is a kind of distilled coffee. The coffee brewed by Moka Maker has a stable taste and aroma. Mocha pot is divided into two parts, the lower part of the pot water is boiled to boiling, water boiling due to steam pressure, rising through the filter containing coffee powder to reach the upper part of the pot. When the coffee starts to flow to the top half of the pot, you need to turn down the fire, because too high a temperature will make the coffee produce a scorched taste and destroy its original flavor. The common Japanese stop-air cooking method (siphon pot) also uses the same principle of thermosiphon. I don't recommend cooking mocha pot, mocha pot really has a greater impact on flavor, cooking fine beans is a waste of heaven.
