BARs (Barometric pressure) is the force your espresso machine exerts upon the grounds of coffee while pumping high-pressure water. The espresso machine is pushing heated water through the grounds of coffee at nine times that of Earth's current atmosphere pressure.
The pressure of your machine is essential because it allows the water to move through coffee grounds at the correct speed and intensity.

For the less expensive home machines that utilize a vibration motor, it's impossible to adjust the pressure with DIY hacks. However, companies such as Cafflano are working on technology that utilizes Pascal's Principle to maintain pressure inside the portafilter throughout the beer making process.
Temperature
The temperature is one of the most important aspects for the perfect espresso shot. If the water is too hot, it will ignite the coffee grounds and produce an over-extracted bitter espresso. The ideal temperature for extraction is 200 degrees Fahrenheit which allows the water to extract all the desired coffee flavors without scorching the grounds, or over-extracting.
