BARs (Barometric Pressure) refer to the force that is imposed on the coffee grounds when your espresso machine is pumping out its high-pressure water. Your espresso machine is pushing hot water through the grounds of your coffee at nine times the current atmospheric pressure.
The pressure of your espresso machine is vital because it's what allows the water to move through the grounds of coffee at the proper speed and intensity. If the pressure isn't sufficient the flavors and oils aren't extracted properly. If the pressure is too low, the flavors and oils dissolved will not be extracted properly.

Temperature
The temperature is among the most crucial factors to the perfect espresso shot. If the water is too hot, it can ignite the coffee grounds and create a bitter espresso.
