Drip filter coffee

The method of cooking invented by the Germans. To put it simply, after grinding the coffee, put it in a funnel or add a layer of filter paper and pour hot water on top (the ideal water temperature is between 90C and 95C). Due to the gravity of the earth, the coffee will flow out from below. The amount of coffee is usually 7 to 10 grams of powder can make about a cup of 120ml.

French filter 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. The taste made by it will be a little thicker, but the degree of change and net taste is relatively low, and the level of presentation is slightly weaker than that of hand flushing. Advantages: convenient, simple technology can make a good cup of coffee, is an important feature. 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. Suitable for coffee: coffee powder with both strong and light taste. Degree of grinding: coarse granule.

Siphon kettle

If you want to taste a little stronger, stretch a little bit, you can choose this siphon cooking method with a chemical laboratory feeling. Some people say that because it can extract the most perfect part of coffee. One of the most popular ways to brew coffee in cafes. Principle: under the burning 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.

Advantages: if you have the right technology, you can make a cup of coffee have both a center of gravity (that is, the main flavor of beans) and change. Disadvantages: the degree of dependence on technology is quite high, and it takes some experience to observe the situation of beans, control the heat and stir. And the assembly and cleaning are complicated. Suitable beans: it used to be medium-baked and slightly deep-baked, but now shallow baked beans are actually played by people. Degree of grinding: slightly thicker than powder, close to special fine granulated sugar.

Mocha pot

The basic principle of mocha pot is to use pressurized hot water to quickly extract coffee liquid through coffee powder. The earliest mocha pot was made by 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. Use precautions: 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. 2. 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.

Belgian royal coffee pot

The Belgian pot, which has the characteristics of both siphon coffee pot and mocha pot, is full of seesaw fun. It combines several natural forces: fire, steam, pressure and gravity, which make the operation of the Belgian royal coffee pot more visible.

Electric coffee machine

The common ones on the market are American coffee dripping machine and Italian steam coffee machine. American drip coffee machine is suitable for moderate or deep roasted coffee 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. The coffee brewed by the Italian steam coffee machine is stronger and the temperature is higher, so it tastes heavier than the coffee brewed by the American dripping machine. The Italian steam coffee maker is a machine that allows steam to quickly extract coffee through coffee powder through high pressure and high temperature. the best temperature for brewing coffee is between 90 and 98 degrees Celsius. Household espresso machines often have a bubbling mouth to make cappuccinos, and often have the function of warming the cup. Suitable for beans: Italian baking, if the mill is good enough to make SOE.
