BARs (Barometric Pressure) refer to the force exerted on the grounds of your coffee when your espresso machine is pumping out its high-pressure water. 9 BARs means that your espresso machine is forcing heated water through the ground coffee at the rate of nine times the Earth's current atmospheric pressure.
The pressure of your machine is crucial because it allows water to move through coffee grounds at the proper speed and intensity. If the pressure isn't high enough the oils and flavors aren't extracted properly. If the pressure is too low the dissolved oils and flavors will not be extracted correctly.
The pressure of your espresso machine can be adjusted by turning the screw on the espresso pump. Commercial machines and some high-end home appliances have rotary pumps that are adjustable. For the more affordable home machines espresso that have a vibrating pump, adjusting the pressure is impossible without involving DIY hacks. However, companies like Cafflano are developing technology that makes use of Pascal's Principle to maintain pressure inside the portafilter during the brewing process.
Temperature
Temperature is one of the most crucial factors in a perfect espresso shot. If the water is too hot, it may ignite the coffee grounds and create an over-extracted bitter brew. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water extract all the desired coffee flavors without burning the grounds or over-extracting.
