BARs (Barometric Pressure) refer to the force that is imposed on the coffee grounds when your espresso machine is delivering its high-pressure water. Your espresso machine is pushing heated water through the grounds of the coffee at a rate nine times the current atmospheric pressure.

The pressure of the espresso machine is crucial because it allows water to move through the grounds of your coffee with the right speed and in the right amount. If the pressure is too low the flavors and oils dissolved will not be extracted properly. On the other side, if the pressure is too high the water will be pushed through the coffee grounds too quickly, and you'll end up with an over-extracted, weak cup of espresso.
