The classic of the mocha pot lies in its octagonal design, as well as the traces left on its body over time. Since it was designed and born in 1933, it has been widely collected in modern industrial gallery and design gallery. Although it is made of metal, its beauty is warm and down-to-earth, which is what coffee at home should look like.

Today, when Italian coffee is popular all over the world, we are no stranger to Italian coffee machine, and even passers-by can name several Italian fancy coffee. But today we have more criticism and discrimination against the mocha pot, and we always question whether the coffee made by mocha is Espresso. So Uncle Dou would like to share some of my views on the mocha pot.

Europeans do not call this kind of pot mocha pot, but call it Espresso Pot. Judging from this name, the coffee made by mocha pot is a veritable Espresso, only that its cup-making form is too classical and simple. Some friends questioned it because it was not as high-tech as the machine, and when it came out of the cup, it could not see the thick layer of fat in the cup, so they concluded that the coffee it made was not Espresso. But such doubts are unconvincing.

The structure of the mocha pot is not complicated. The body of the mocha pot is divided into three parts: the bottom pot (A) contains water, and when the mocha pot is heated, the air pressure of the lower pot rises, pushing hot water rises through the diversion tube, permeates the powder trough (B) containing coffee powder for extraction, and finally rises to the top and flows into the upper pot (C). But there is an important structure on the mocha pot called the safety valve, which is used to vent air. When you heat the mocha pot, the air pressure in the kettle will rise, so there are two ways to relieve the pressure, either through the coffee powder layer, or if the air pressure exceeds the safety threshold, to relieve pressure from the safety valve.
