BARs (Barometric pressure) is the amount of force that your espresso machine exerts upon the grounds of the coffee while delivering high-pressure water. 9 BARs mean 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 important because it allows water to pass through coffee grounds at the proper speed and intensity. If the pressure isn't sufficient, the oils and flavors won't be extracted properly. If the pressure is too low the flavors and oils dissolved won't be extracted properly.
You can control the pressure of your espresso maker by adjusting the screw on the espresso maker. Commercial machines and some high-end home appliances have rotating pumps that can be adjusted. For the cheaper home machines that use a vibrating pump, adjusting the pressure is difficult without using DIY hacks. Companies such as Cafflano however, are working on technology that uses Pascal's Principle in order to maintain pressure in the portafilter during the fermentation process.
Temperature
The temperature is one of the most crucial factors to a great espresso shot. Too hot water can burn the grounds of the coffee, resulting in bitter espresso. The ideal temperature for extraction is 200 degrees Fahrenheit. This allows the water extract all the desired coffee flavors without burning the grounds or excessively extracting.
