BARs (Barometric pressure) is the force your espresso machine exerts upon the coffee grounds while delivering high-pressure water. 9 BARs mean that your espresso machine is pushing heated water through the ground coffee at 9 times the Earth's current atmospheric pressure.
The pressure of your machine is vital because it allows water to flow through coffee grounds at the right speed and intensity.

Companies like Cafflano, however, are working on technology that utilizes Pascal's Principle in order to maintain pressure in the portafilter during the beer making process.
Temperature
Temperature is one of the most important factors in a great espresso shot. If the water is too hot, it will cause the coffee grounds to burn and produce an over-extracted bitter espresso.
