Choosing a home espresso machine is not just about looks and the number of boilers. One of the most important, yet often overlooked, factors is the group head — the part through which water passes to the coffee.

What is a group head?

The group head is the part of the machine where you insert the portafilter. This is where the crucial part of the process happens — pressurized water at a precise temperature passes through the ground coffee. The quality and stability of this part directly affect the taste and consistency of the espresso.
