The coffee made by Italian coffee machine and extracted directly from the coffee machine is called Espresso.
The biggest feature of espresso is to extract a cup of high concentration coffee by using the pressure of 9bar.
Hand-brewed coffee is also an extraction method. Hand-brewed coffee is a kind of free-falling extraction without pressure. In the whole extraction process, the speed of water flowing through coffee powder is the key to extraction.
The biggest feature of hand-brewed coffee is to express the taste of coffee beans very primitive. Different coffee beans can be brewed by hand to brew the taste of coffee. Plus, compared with italian coffee machine, the convenience of making coffee by hand is obvious.
