Pressure
If you're serious about coffee then you're aware that the pressure of your espresso machine is a crucial factor in how well your drinks taste. It doesn't matter if you're seeking an even layer of crema or the perfect balance of acidity and flavor, the pressure of your espresso machine is the key to brewing great espresso.
BARs (Barometric Pressure) refer to the amount of force exerted on the grounds of your coffee when your espresso machine is delivering its high-pressure water. 9 BARs means that your espresso machine is pushing heated water through the ground coffee at a 9 times the Earth's current atmospheric pressure.
The pressure of your machine is essential because it allows water to pass through coffee grounds at a proper speed and intensity. If the pressure isn't high enough the oils and flavors will not be extracted correctly. If the pressure is too low the dissolved oils and flavors won't be extracted properly.
The pressure of your espresso machine can be controlled by adjusting the screw on the espresso pump. Commercial machines and some of the top-end home appliances use pumps with rotary that can be adjusted. For the cheaper home machines that utilize a vibration motor, it's not possible to adjust the pressure without DIY hacks. Companies such as Cafflano however, are developing technology that utilizes Pascal's Principle in order to maintain pressure within the portafilter throughout the brewing process.
Temperature
Temperature is among the most important aspects in a great espresso shot. If the water is too hot, it may heat the coffee grounds and produce an over-extracted bitter drink. The ideal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all of the desired coffee flavors without burning the grounds or excessively extracting.
The best espresso machines will feature a thermoblock, or thermocoil which warms the water and keeps it at a constant temperature throughout the entire extraction cycle. The Breville Barista Express, for example, has a PID (Proportional Integral Derivative) system that constantly monitors the water temperature and adjusts it as needed making sure that the brewhead remains at the perfect temperature to extract the coffee.

Some machines come with an analog pressure gauge, which looks cool and can help you learn about the brewing process. check here The ideal goal is to achieve around nine bars of pressure, and keep it throughout the brewing process. This machine is near reaching that goal.
Another great feature of this machine is its built-in burr grinder. This is a fantastic feature for newbies to espresso as it will not require you to buy a separate burr grinder. The grinder is a conical stainless steel unit that has 18 settings from "coarse" to "fine."

This will give you the right balance between acidity and hardness, and prevent the need to decalcify.
A high-quality, filtered water is vital to your machine's overall health and the flavor of the coffee it produces.
