BARs (Barometric Pressure) refer to the force exerted on the grounds of your coffee when your espresso machine is pumping out its high-pressure water. 9 BARs means that your espresso machine is pushing heated water through the ground coffee at a rate of nine times the Earth's current atmospheric pressure.
The pressure of your machine is important because it allows the water to pass through the coffee grounds at the proper speed and intensity. If the pressure is too low the flavors and oils that are dissolved won't be properly extracted. If the pressure is too low the flavors and oils dissolved won't be extracted properly.
You can control the pressure of your espresso maker by changing the screw that is attached to the espresso pump. Commercial machines and some of the top-end home machines have the rotary pumps, which are adjustable. However, for the less expensive home appliances that utilize the pump that vibrates, adjusting the pressure is impossible without getting into DIY hacks. However, companies like Cafflano are working on technology that employs Pascal's Principle to create maintained pressure in the portafilter during the fermentation process.
Temperature
The temperature is one of the most important aspects for the perfect espresso shot. A hot water can burn the coffee grounds, resulting in bitter coffee. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water extract all the desired coffee flavors without burning the grounds or over-extracting.
The best espresso machines will feature a thermoblock, or thermocoil that warms the water and keeps it at a constant temperature throughout the whole extraction process. The Breville Barista Express has a PID system (Proportional Integral Derived) that constantly monitors and adjusts the temperature. This ensures that the brewhead remains at the ideal temperature for extraction.
Most coffee lovers are aware that the temperature of an espresso machine is crucial to brewing a perfect cup of coffee. The ideal temperature for brewing espresso is between 190 and 196 degrees Fahrenheit.

Grind
A barista espresso machine must provide a variety grind settings to give you the best control over the final cup of coffee. Some machines include an analog gauge which looks cool and aids you to improve your brewing skills.

Another nice touch on this machine is the built-in burr grinder. This is a wonderful feature for newbies to espresso as it doesn't require them to purchase an additional burr grinder. The grinder is an stainless steel conical unit with 18 settings ranging from "coarse" to "fine."
The grinder isn't the same as a stand-alone unit, but it's a good start and will have you on the path to brewing quality espresso shots.

The ideal espresso water is soft and high in alkalinity. This can be achieved with an effective water filtering system that removes chlorine and puts back a small amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will create a balanced balance of alkalinity retro espresso machine and hardness and reduce the necessity to decalcify your equipment.
Using high-quality filtered water is crucial to your machine's long term health and the taste of the coffee it makes. Descaling products should be used on a regular basis, depending on the hardness and use of your machine. They are available in powder, liquid or tab form at most hardware stores.
