This machine was a huge success and helped spread the prosumer (home barista) espresso market. Features include a low pressure pre-infusion as well as an 2.2L boiler, and brewing pressure of 9 bar.
Pressure
If you're a coffee lover, you'll realize that the pressure of your espresso machine is an important factor in the quality of your coffee. If you're looking for an even layer of crema or right balance of flavor and acidity, the pressure of your espresso maker is essential to making perfect espresso.
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 the espresso machine is forcing heated water through the ground coffee at a rate of nine times the current atmospheric pressure.
The pressure of your machine is essential because it allows the water to pass through the coffee grounds at the correct speed and intensity. If the pressure is low the oils and flavors won't be extracted properly. On the other hand, 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, diluted cup of espresso.
The pressure of your espresso machine can be controlled by adjusting the screw found on the espresso pump. Commercial machines and some high-end home appliances use rotary pumps that are adjustable. For the more affordable home appliances that utilize the vibrating pump, altering the pressure is difficult without engaging in DIY hacks. Companies like Cafflano however, are developing technology that is based on Pascal's Principle to ensure pressure in the portafilter during the beer making process.
Temperature
Temperature is among the most important elements in the making of a good espresso shot. A hot water can burn the coffee grounds, resulting in bitter drink. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all of the desired coffee flavors without scorching the grounds or causing excessive extraction.
The best espresso machines will have a thermoblock or thermocoil that warms the water and keeps it at a constant temperature throughout the whole extraction process.

It is also important to pre-heat your espresso maker or portafilter before making espresso. Beginners often make the mistake of not preheating their machine. It is advisable to read your espresso machine's instruction manual before you try it for the very first time.
Grind
A barista machine ought to give you a range of grind settings to ensure that you have the best control over your final cup of espresso. Some machines have an analog pressure gauge that looks cool and can help you gain knowledge about your brewing techniques. In the ideal scenario, you'll want to hit about nine bars of pressure, and keep that throughout the brewing cycle. This machine is very close to getting to that point.
Another excellent feature of this machine is the built-in burr grinder. This is a fantastic feature for espresso newbies because it doesn't require them to purchase a separate burr grinder. The stainless steel conical grinder features 18 settings, ranging from "coarse to fine."

The ideal water for espresso is soft and high in alkalinity. This is best achieved by using an water filter system that bypasses all chlorine and adds an amount of total dissolved solids (TDS) to add some calcium and magnesium to the mix. This will give you a good balance between hardness and acidity and will also prevent the need to decalcify.
It is crucial to use water filtered of excellent quality for the health and flavor of your machine. Based on the usage and hardness of your machine, you should use descaling products on a regular basis. They are available in liquid, powder and tab forms and are available at many hardware stores.
