Pressure
If you're a coffee lover, you'll realize that the pressure of your machine is an important element in the quality of your drinks. If you're looking for an even layer of crema or right balance of flavor and acidity The pressure of your espresso machine is the key to brewing perfect espresso.
BARs (Barometric Pressure) refer to the amount of force that is imposed on the grounds of your coffee when your espresso machine is delivering its high-pressure water. 9 BARs means that your espresso machine is forcing heated water through the ground coffee at a 9 times the Earth's current atmospheric pressure.
The pressure of the espresso machine is crucial because it's what allows the water to move through the grounds of your coffee with the right speed and in the right amount. If the pressure is too low, the dissolved oils and flavors won't be properly extracted. On the other contrary, if pressure is too high the water will be pushed through the coffee grounds too fast and you'll end with a weak, over-extracted cup of espresso.
The pressure of your cheap espresso machine machine can be adjusted by turning the screw that is located on the espresso pump. Commercial machines and some of the top-end home appliances use rotary pumps that are adjustable. For home machines that are less expensive, which use a vibrating motor, it is not possible to alter the pressure without hacks. Companies like Cafflano however, are developing technology which uses Pascal's Principle to ensure pressure within the portafilter throughout the making process.
Temperature
The temperature is one of the most important factors in brewing an excellent espresso shot. If the water is too hot, it may ignite the coffee grounds and create a bitter coffee. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all the desired coffee flavors without burning the grounds or causing excessive extraction.
The best espresso machines will feature a thermoblock, or thermocoil that will heat the water, and keeps it at a stable temperature throughout the entire extraction process.

Using a high-quality filter water is crucial to your machine's long term health as well as the taste of the coffee it makes.
