It doesn't matter if you're seeking a thick layer of crema or the perfect balance of acidity and flavor the pressure of your espresso machine is the most important factor in brewing perfect espresso.
BARs (Barometric pressure) is the force your espresso machine exerts on grounds of coffee while pumping high-pressure water. Your espresso machine is pushing hot water through the grounds of coffee at nine times the current atmospheric pressure.
The pressure of your espresso machine is vital because it's what allows the water to pass through the coffee grounds at the right speed and in the right amount. If the pressure is too low, the flavors and oils dissolved will not be extracted properly. If the pressure is too low the flavors and oils dissolved won't be extracted properly.
The pressure of your espresso machine can be adjusted by turning the screw that is located on the espresso pump. Commercial machines as well as some high-end home machines use pumps with rotary that can be adjusted. For home-based machines that have a vibrating motor, it is not possible to adjust the pressure without hacks. Companies such as Cafflano, however, are developing technology which uses Pascal's Principle to ensure the pressure within the portafilter all through the fermentation process.
Temperature
Temperature is one of the most important elements in a perfect espresso shot. If the water is too hot, it will cause the coffee grounds to burn and create an over-extracted bitter brew. The ideal temperature for extraction is around 200 degrees Fahrenheit which allows the water to extract all of the desired flavors of coffee without scorching the grounds, or over-extracting.
