Six common brewing methods of coffee

one. Trickling filter: the structure of this trickling filter pot is very simple, only a conical container, much like a cup, the inner edge of the container must be covered with filter paper, put in coffee powder, soak in hot water. This method makes the hot water connect with the coffee powder once, and then fall into the cup, so it will only extract the substances that play a higher level, so you can brew the coffee with the least flavor and fragrance.

two. American electric coffee maker: there are two kinds of internal containers of the general electric coffee maker, one is funnel type, the other is wide and flat cylindrical shape. I suggest using the former when cooking curry in small quantities. Coffee powder will be concentrated in the narrow bottom, slowing down the flow of hot water, while in the latter, coffee powder can only be laid flat on the bottom of the box, a thin layer, when the hot water quickly passes through. There was no coffee. At present, most of the internal nozzles of hungry electric coffee machines in the world spray hot water around, but the amount of coffee powder is so small that part of the hot water can only be sprayed to the filter paper, but not to the coffee powder. So most of them are brewed into a cup of diluted coffee!

three. French filter press: the pressure filter can best show the original flavor and wild, its operation principle, directly brew coffee with hot water, and filter with iron mesh, almost extract all the substances that can be extracted, so it will form a cup of turbid coffee. And the flavor is very primitive and complicated. General high-quality coffee is very suitable for this brewing method. But shoddy coffee beans have no flavor at all. All that remains is bitterness.

four. Siphon pot: many people think that the coffee grounds left in the pot have to be shaped into a hill to be considered a successful brewing. However, I do not think this statement is necessarily correct. Because in the middle of the upper pot is the position of the filter cloth, it is actually very easy to form a hill as long as the siphon pot leaves the fire, that is, the upper pot of coffee is ready to stay in the lower pot, as long as you stir it a few times clockwise with a coffee stirring stick, of course, in the opposite direction! In fact, the siphon pot uses the air pressure of a water pipe to move the water in the lower half of the container to the upper half of the container to become a cup of coffee. So it is also called vacuum pot and plug air pot. Basically, siphon pots are not used in Europe and the United States, but they are very popular in Japan, Taiwan and the mainland. maybe we are playing with glassware on the bar, like doing chemical experiments, making people think that this is a very esoteric skill. I think this way of brewing coffee is the best.

five. Mocha pot: the mocha pot is composed of the upper pot, the filter screen and the lower pot, which is between the upper and lower pots. When brewing, the water is placed in the lower pot and the coffee is placed in the middle of the net. when the pot is heated, it produces steam and rushes the hot water up. Pass through the coffee powder, then into the pot to form coffee. Because its air pressure is relatively high, some people classify it as high-pressure cooking. Some people call it hand-made espresso, but it can't make the foam of espresso. But it's really exciting coffee.

six. Italian espresso machine: Espresso is an easy to use technology to brew coffee, a cup of Espresso standard, coffee powder in about 7 grams, water temperature of about 95 degrees, water pressure in about 10 atmospheric pressure, brewing time between 22-28 seconds. If the water temperature is too low, it will cause insufficient extraction and can only boil a cup of Espresso with insufficient flavor and sour taste. However, if the water temperature is too high, it will cause the coffee to be too bitter and astringent. And the mellow taste mainly comes from its water pressure, the general hot water rinse robe method, can only hold coffee in water substances, and can use high pressure to extract coffee can not hold water substances. These high pressures completely emulsify the lipids in the coffee and enter the water. Its brewing time will determine the characteristics of this cup of coffee. Espresso uses high pressure to extract the flavor of the coffee, which is completed in about 25 seconds. The coffee that flowed out after the timeout was no longer tasteless. It will only dilute Espresso.
