This machine was a huge success and helped popularize the prosumer (home barista) espresso market. Features include a 2.2L steam boiler, a low pressure pre-infusion and 9 bar pressure for brewing.


Pressure

If you're an avid coffee drinker, then you'll know that the pressure of your machine is a crucial element in the quality of your coffee. Whether you're looking for an even layer of crema, or the right balance of acidity and flavor, the pressure of your espresso machine is the most important factor in brewing excellent espresso.

BARs (Barometric pressure) is the force your espresso machine exerts on the coffee grounds while delivering high-pressure water. 9 BARs mean that your espresso machine is forcing heated water through the ground coffee at 9 times the current atmospheric pressure.

The pressure of your espresso machine is crucial because it allows the water to move through the grounds of your coffee with the right speed and with the right intensity. If the pressure isn't sufficient, the oils and flavors won't be extracted properly. If the pressure is too low, the dissolved flavors and oils will not be extracted properly.

You can regulate the pressure of your espresso maker by changing the screw on the espresso pump. Commercial machines and high-end home machines have rotary pumps with adjustable pressure. However, for the less expensive home machines that have an oscillating pump, changing the pressure isn't possible without engaging in DIY hacks. Companies such as Cafflano however, are working on technology that uses Pascal's Principle to ensure the pressure inside the portafilter throughout the making process.

Temperature

The temperature is among the most important factors in brewing a great espresso shot. The water that is too hot can scorch the grounds of the coffee, resulting in bitter coffee. 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 over-extracting.

Grind

A barista espresso machine must provide a variety grind settings for you to have the most control over the final cup of coffee. Some machines include an analog pressure gauge, which looks cool and can help you gain knowledge about the brewing process.

A built-in burr mill is a great feature. This is an excellent feature for people who are new to espresso since it will not require you to pay for an additional burr grinder. The grinder is a conical stainless steel unit with 18 settings ranging from "coarse" to "fine."

The perfect water for espresso is low in hardness and high in alkalinity. It is recommended to use a filter which does not use chlorine and adds a small amount (TDS) of total dissolved substances that add calcium and magnesium. This will create a good balance of alkalinity as well as hardness. It will also avoid the necessity of decalcifying your machine.

Using a high quality filtered water is vital to your machine's longevity health as well as the taste of the coffee it produces.
