What is a 20 bar coffee machine?
A 20-bar espresso machine has a pump capable of creating up to 20 bars of pressure. While this might seem superior, the brewing process still uses 9 bars for optimal espresso. The higher rating ensures enough power to overcome resistance, but it doesn’t guarantee better coffee quality. The ideal level of BAR passing through your coffee grounds should be around 7-11 BARs of pressure, though some espresso machines will be able to hit higher BAR. Machines capable of hitting 9 BARs of pressure will have the ability to produce a rich and concentrated espresso shot.Nine bars of pressure, which is nine times the weight of air at sea level, is the gold standard for extracting consistently great espresso in a 25- to 30-second time frame. Any higher or lower level of pressure results in imperfect extraction, typically producing espresso that is too strong or too weak.Bars of Pressure and Above Some espresso machines boast pressure ratings of 20 bars or more. While these high numbers might seem impressive, they don’t necessarily translate to better espresso.
