What difference does the bar pressure makes in

2019-5-19 · The standard pressure is 15 bar for home machines and 9 bar for professional machines! If so, why are there machines with higher pressure (16, 19, 20, 21 bar) and why do these machines cost more money? If professional coffee is made with 9 bar, then why do home machines work with 15 bar?
