The biggest difference between espresso machines and brewing methods like pour-over and French press is that they use pressurized extraction. It is precisely the presence of pressure that allows espresso to complete extraction in an extremely short time and form that iconic golden layer of Crema. Generally speaking, the extraction pressure of a coffee machine fluctuates around 9 bar, but many home coffee machine users find that the pressure struggles to climb to 9 bar and often stays between 5 bar and 7 bar, resulting in weak and sour coffee. The key behind this actually lies in whether the resistance of the puck is sufficient. This article will analyze the reasons for insufficient pressure and provide specific adjustment suggestions from three aspects: grind size, dose, and tamping force, to help you extract rich and balanced espresso at home as well.
