What kind of machines do you need to do espresso at home?
Espresso can't be cooked with an ordinary coffee machine, so buy a special machine. Basically, there is one called steam machine and one called pump machine. How can you tell the difference? It's easy, as long as there's a lid that has to be rotated to open, it's steam machine! The steam engine can't make a real espresso! So almost all the experts will tell you not to buy it.
The reason why steam machine can't do espresso well is very simple. Its pressure is only about three atmospheres, and the real espresso is about 8.2-9 atmospheres! To make matters worse, the steam engine is powered by steam to press the water over the coffee powder. But what is the temperature of the water at this time? Use your knees to know how to exceed the boiling point! Water above the boiling point should never be used to make coffee!
Since steam machine is not a good choice, how can we choose PUJI? Don't worry, a help machine is not cheap. You'd better study it carefully on the Internet for a month to find out whether the characteristics of each model are suitable for you, and then "do it".
