The method of extracting Coffee essence

Soaking method

The easiest way is to put the coffee powder in the cup and add hot water. As it cools, the coffee powder will sink to the bottom of the cup. This is an old method, and it is still used in some parts of Indonesia. Be careful not to eat the coffee at the bottom of the cup. The advantage of this method is that it is simple and the water temperature is just right.

Turkish coffee is an early prescription and is still used in the Middle East, North Africa, East Africa, Turkey, Greece and the Balkans. Ultra-fine coffee powder is boiled with water in a small container, usually seasoned with sugar and cardamom. The espresso in the cup has foam on it and a layer of silted powder underneath.

"Cowboy Coffee" is to boil the minced coffee directly in the pot and drink it. The name implies a stopgap measure under humble conditions; however, some people prefer it. This is their traditional cooking method in Finland and Sweden, where per capita consumption of coffee is the highest.

Pressure method

Espresso is made from 80 to 96 degrees Celsius hot water at a force of 8 to 9 atmospheres through compacted coffee cakes, usually only 30 milliliters per cup. It is one of the strongest of the common coffee, with a unique aroma and a touch of oil (Crema) floating on the surface. It can be drunk alone; it can also be further made into a variety of other drinks. Because of its fast brewing speed, high concentration and low caffeine content, this method is used in many chain coffee shops or seasoned coffee.

The mocha pot, also known as the Italian coffee pot, is a three-layer stove. After boiling water at the bottom, the coffee powder is pushed through the middle layer by steam pressure to enter the upper layer, and the coffee concentration obtained is comparable to that of espresso, but there is no oil slick, but if a pressure gasket is installed at the coffee spill outlet, the golden crema can be extracted. The mocha pot and the semi-automatic espresso machine have the same structure, but the way the water comes out is upside down. Remove the fire from the bottom of the pot as soon as possible after the coffee spills about 30~40cc, and then wipe it on the bottom with a cold towel.

Gravity method

American coffee, espresso. In the 1970s, electric circulating filters used different mocha pots: hot water boiled into the top layer, and then passed from top to bottom through the end of hot water many times, and the flavor of this coffee was unstable.

Leaching method

The French filter Press (French press) is a tall thin glass cylinder with a piston with a filter. Soak the hot water and coffee powder in a cylinder for four to seven minutes, then press the coffee powder to the bottom by a piston filter, and the top coffee can be poured out to drink. This "complete immersion method" is considered by many experts to be an ideal household method for making coffee.

Coffee bag is a portable package for travel, which is very rare at ordinary times.

Malaysians put coffee powder in cotton pockets, soak them in hot water, and then remove the cloth bags from the hot water. This kind of pocket is the same as using filter paper. This is more suitable for strong local coffee, and the coffee in the bag can be reused.

The siphon coffee maker (Syphon) is made by connecting a heating container and a funnel container. The connecting part is a filter with coffee dust on it. After boiling in the heating container, the water goes into the funnel container and mixes with the coffee powder; at this time, the heating source is cut off, and the partial vacuum formed by the cooling of the heating container pulls the coffee back to the bottom through the filter.

Ice brewing method

Ice brewed coffee, also known as ice drop coffee, is the biggest difference from the above four, that is, instead of using hot water, ice water produced by slowly melting ice is dripped slowly through a filter containing coffee dust. So making a cup of ice-brewed coffee takes a long time and costs a lot, but it tastes great.
