Various utensils and principles for making coffee-1

■ filter / hand brew (Filter Coffee): the most popular way for coffee players to brew coffee is to use lightly roasted and roughly ground coffee powder into 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 around (no matter how the water is injected, evenness is the most important) Soak the coffee powder in hot water and drop it into the sharing pot to complete the extraction. Each cup of coffee consumption of about 8 grams of coffee powder, hot water needs to use 85-95 ℃ of hot water.

■ mocha pot (Moka Maker): a kind of distilled coffee brewed from the mocha pot with a steady concentration and aroma. The mocha pot is divided into two parts. The water is boiled in the lower half of the pot until it boils. When the water boils, due to the pressure of the steam, the boiling water rises through a filter containing coffee powder and reaches the upper half of the pot. When the coffee starts to flow to the top half of the pot, the fire needs to be turned down, because the high temperature will make the coffee scorch and destroy its original flavor. The common Japanese plug-air cooking method (siphon pot) also uses the same principle of thermosyphon. Personally, it is not recommended to cook mocha pots. Mocha pots do have a great influence on flavor, and cooking high-quality beans is a natural thing.

■ espresso machine (Espresso Machine): coffee drinks are extremely unstable liquids that can change their characteristics and taste at once. This is the main reason why the espresso machine (Espresso Machine) was invented. The espresso machine can continuously extract several cups of coffee, and the high pressure in the brewing process can emulsify and melt the oil and gum in the coffee beans, and the essence of the coffee beans can be completely extracted by pressure, making the brewed coffee more concentrated and more mellow in taste and flavor.

■ siphon pot (Siphon): there are generally two ways to cook the siphon pot. One is to put the coffee powder into the upper funnel, then add water into the lower pot, then put the funnel mouth tightly into the pot mouth, boil the water, when the boiling water goes deep into the funnel, stir for about 40 seconds and 60 seconds, then extinguish the heating apparatus. When the coffee falls back into the pot, you can remove the funnel and pour out the coffee to drink. The other is to boil the water first, then pour the coffee powder into the upper pot, stir and soak for about 40-60 seconds, turn off the heating apparatus, and wait for the coffee to flow back to the next pot, then remove the funnel and pour out the coffee to drink.
