一、 The history and principle of mocha coffee pot
The first Mocha pot was made by Italian Alfonso Bialetti in 1933, and his company Bialetti has always been famous for producing this coffee pot called “Moka expres”. The traditional Mocha pot is made of aluminum and can be heated by an open fire or an electric stove. Because the aluminum Mocha pot can’t be heated on the electromagnetic cooker, modern mocha pots are mostly made of stainless steel, and there are electric heating mocha pots like electric kettle.
The working principle of the mocha coffee pot is as follows: the mocha pot is divided into upper and lower pots. The lower pot is filled with water, which will be heated on the open fire. After the water boils, the pressure accumulated by steam will push the hot water to the upper pot. During this period, it will penetrate the coffee powder layer in the middle and extract the coffee. Finally, the coffee that tastes close to Italian concentrate will be poured out.

When the water level is 0.5cm below the safety valve, the safety valve will automatically release the pressure when the pressure of the kettle is too high, so as to prevent safety accidents; if the water level is higher than the safety valve, the function of the safety valve will not work normally. Warm water can also be used to reduce heating time.
2. Add coffee powder
Use medium and fine-grained coffee powder. When loading, vibrate the powder trough properly to make the coffee powder evenly distributed. After the coffee powder is filled, gently press the surface with your fingers to make the coffee powder more dense.
3. Tighten
