What to Look For in a Barista Espresso Machine

This machine was a huge success and helped popularize the prosumer (home barista) espresso market. Features include a low pressure pre-infusion, the 2.2L boiler, and the brewing pressure of 9 bars.
Pressure
If you're serious about your coffee then you're aware that the pressure of your espresso machine is a crucial factor in how your drinks are made. If you're looking for an even layer of crema or perfect balance of flavor and acidity The pressure of your espresso machine is crucial to making excellent espresso.
BARs (Barometric Pressure) refer to the force that is applied to the grounds of your coffee when your espresso machine is delivering its high-pressure water. 9 BARs means that the espresso machine is pushing heated water through the ground coffee at a 9 times the current atmospheric pressure.
The pressure of your machine is vital because it allows the water to flow through coffee grounds at the proper speed and intensity. If the pressure isn't sufficient, the oils and flavors will not be extracted correctly. On the other hand, if the pressure is too high, the water will be forced through the coffee grounds too quickly and you'll end up with an over-extracted, weak cup of espresso.
The pressure of your espresso machine can be controlled by adjusting the screw located on the espresso pump. Commercial machines and some high-end home appliances use rotary pumps that are adjustable. For the less expensive home machines that utilize a vibration motor, it's not possible to adjust the pressure without DIY hacks. However, companies such as Cafflano are working on technology that employs Pascal's Principle to maintain pressure in the portafilter during the beer making process.
Temperature
The temperature is among the most crucial factors to an excellent espresso shot. Hot water can cause burning of the grounds of the coffee, resulting in bitter espresso. The ideal temperature for extraction is about 200 degrees Fahrenheit, which allows the water to extract all of the desirable coffee flavors without scorching the grounds or over-extracting.
The best espresso machines feature the thermoblock, also known as a thermocoil that heats water and maintains it at the same temperature throughout the extraction process. The Breville Barista Express, for example, features a PID (Proportional Integral Derivative) system which constantly monitors the temperature of water and adjusts it as needed, ensuring that the brewhead stays at the right temperature for extraction.

Grind
A barista machine ought to give you a range of grind settings so that you can have the greatest control over the final cup of espresso. Some machines come with an analog pressure gauge which looks cool and can help you gain knowledge about your brewing skills. In the ideal scenario, you'll want to hit about nine bars of pressure and keep this throughout the entire brewing process. While this website machine does not hit that target, it is pretty close and will be able to serve you well.
Another nice touch on this machine is a built-in burr grinder. This is a wonderful feature for those who are new to espresso because it eliminates the need to purchase a separate burr grinder. The stainless steel conical grinder comes with 18 settings, which range espresso coffee machine home from "coarse to fine."

The ideal espresso water is soft and high in alkalinity. It is recommended to use a water filter that removes chlorine and adds a small amount (TDS) of total dissolved substances in order to add calcium and magnesium. This will result in a balanced balance of alkalinity as well as hardness. It will also reduce the necessity of decalcifying your equipment.
Using a high quality filtered water is vital to your machine's longevity health as well as the taste of the coffee it produces. Based on the type of use and the hardness of the machine, you should use descaling products on a regular basis.
