What to Look For in a Barista Espresso Machine

BARs (Barometric Pressure) refer to the force applied to the grounds of your coffee when your espresso machine is pumping out its high-pressure water. 9 BARs indicates that your espresso machine is forcing heated water through the ground coffee at a an amount of nine times the Earth's current atmospheric pressure.
The pressure of the espresso machine is crucial because it allows water to move through the grounds of coffee at the proper speed and intensity. If the pressure is too low the flavors and oils dissolved will not be extracted properly. On the other side, if the pressure is too high the water will be forced through the coffee grounds too fast, and you'll end up with a weak and over-extracted cup of espresso.

However, companies like Cafflano are developing technology that makes use of Pascal's Principle to maintain pressure in the portafilter during the beer making process.
Temperature

The ideal water for espresso is soft and high in alkalinity. It is best to use a filter which does not use chlorine and adds a tiny amount (TDS) of total dissolved substances in order to add calcium and magnesium. This will ensure an ideal balance between acidity and hardness and avoid the need to decalcify.
It is vital to use water filtered of high quality for the health and taste of your machine. Descaling products must be regularly used based on the hardness and use of your machine. The products are available in liquid, powder or tab form at a majority of hardware stores.
