Coffee knowledge six common ways of brewing coffee

1. Siphon pot (Syphon)

One of the most popular ways to brew coffee in cafes.

Principle of siphon pot: under the combustion of alcohol lamp, when the water temperature in the lower container reaches 92 ℃, the water is sucked into the upper container with coffee powder, and after soaking and stirring, the coffee is returned.

Suitable for coffee: slightly sour, medium-bodied coffee.

Degree of grinding: slightly thicker than powder, close to special fine granulated sugar.

Siphon cooking has the feel of a chemical laboratory. Some people say that because it can extract the most perfect part of coffee, especially the characteristics of coffee beans with that kind of refreshing and bright acid, and the acid has a mellow flavor, siphon cooking can give full play to the characteristics of this kind of coffee.

two。 Mocha pot (Moka Pot)

The basic principle of mocha pot is to use pressurized hot water to quickly extract coffee liquid through coffee powder.

The earliest mochabi mocha pot was made by the Italian Alfonso Bialetti in 1933, and his company, Bialetti, has always been famous for producing this kind of coffee pot. Mocha coffee pots are commonly used in Europe.

The mocha pot is divided into two parts: the water is put in the lower part to boil and boil to produce vapor pressure; the boiling water rises and passes through the filter pot containing coffee powder; when the coffee flows to the upper half, turn down the fire, if the temperature is too high, the coffee will smell scorched.

Considerations for use:

1 > Water level: use warm water, the water level is 0.5 cm under the safety valve. The safety valve will automatically relieve pressure when the lower pot pressure is too high, in order to prevent safety accidents. If the water level is higher than the safety valve, the function of the safety valve can not play normally.

Coffee powder: coffee powder is medium-fine-grained and filled with powder trough. when filling the powder, vibrate the powder trough properly so that the coffee powder is evenly distributed. after filling it, gently press the surface with your fingers to make the powder denser.

3. Belgian royal coffee pot

It combines several natural forces: fire, steam, pressure and gravity, which make the operation of the Belgian royal coffee pot more visible. The whole cooking process is like a coffee maker for a stage play, because the dazzling and gorgeous appearance, coupled with the full fun of gimmick operation, greatly increases the score of coffee sensibility and romance. This magnificent coffee extraction process, coupled with its own exquisite work of art, makes it practical, ornamental and collectible, unmatched by any other coffee pot. When the coffee dances with the Belgian pot, it is the brightest part of the night. The whole process of making coffee is worth watching again and again. It's amazing.

4. French filter press (French Press)

French pressure pot for short, is a kind of coffee pot with the function of tea maker at the same time.

Principle: by the way of soaking, the essence of coffee is released through the stewing method of full contact between water and coffee powder.

French pressing pot is suitable for coffee: coffee powder with both strong and light taste.

Degree of grinding: coarse granule.

Disadvantages: due to the metal filter can not completely filter fine powder, coffee beans need rough grinding, coffee powder particles become thicker, resulting in a large number of contents can not be extracted. And soaking for a long time will lead to excessive extraction, bitter taste, astringent taste and miscellaneous flavor, so the taste of coffee is slightly inferior.

5. American drip coffee machine

The price of the American drip coffee maker is comparable to that of the siphon pot, which is suitable for coffee roasted in medium or deep depth, with slightly fine grinding particles and bitter taste. It uses electricity to boil the water and soak it. Black coffee is the easiest to do, but it tastes a little worse because it is made from boiling water. In contrast, American coffee machines are more suitable for young people who are petty bourgeoisie and afraid of trouble.

6. Italian coffee maker

The coffee brewed with the Italian coffee machine is stronger, the temperature is higher, and the taste is heavier than the coffee brewed by the American dripping machine. Espresso machine is a kind of machine that allows steam to quickly extract coffee through coffee powder through high pressure and high temperature. Italian coffee machine temperature control is quite good. Household espresso machines often have a bubbling mouth to make cappuccinos; in addition, they often have the function of warming the cup, which is a very important detail. If you hold coffee in a cold cup, it tastes bad.
