What to Look For in a Barista Espresso Machine

This machine was a huge success and helped spread the prosumer (home barista) espresso market. It features a 2.2L steam boiler, a low pressure pre-infusion, and 9 bar pressure for brewing.
Pressure
If you're a coffee enthusiast, you'll know that the pressure of your espresso machine is a key element in the quality of your beverages. Whether you're looking for an even layer of crema or the perfect balance of flavor and acidity The pressure of your espresso machine is essential to making good 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 indicates that your espresso machine is pushing heated water through the ground coffee at a 9 times the current atmospheric pressure.
The pressure of your espresso machine is important as it allows the water to move through the coffee grounds at the right speed and intensity. If the pressure is too low the flavors and oils that are dissolved won't be extracted properly. On the other contrary, if pressure is too high, the water will be forced through the coffee grounds too quickly and you'll end with a weak, over-extracted cup of espresso.
The pressure of your espresso machine can be controlled by adjusting the screw that is located on the espresso pump. Commercial machines and high-end home machines come with rotating pumps that can be adjusted in pressure. For the cheaper home machines that utilize the vibrating pump, altering the pressure isn't possible without involving DIY hacks. Companies like Cafflano however, are working on technology that uses Pascal's Principle to ensure pressure within the portafilter throughout the making process.
Temperature
The temperature is one of the most crucial factors to a great espresso shot. If the water is too hot, it will heat the coffee grounds and produce an over-extracted bitter brew. 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 top espresso machines come with the thermoblock, or thermocoil which heats the water and keeps it at a constant temperature throughout the extraction. The Breville Barista Express, for instance, is equipped with PID (Proportional Integral Derivative) system which constantly monitors the temperature of the water and adjusts if needed making sure that the brewhead remains at the perfect temperature for extraction.
Many coffee drinkers are espresso home machine aware that the temperature of the espresso maker is essential to making a great cup of coffee. The ideal brewing temperature for espresso is between 190 to 196 degrees Fahrenheit. To achieve this, your machine must have a quality thermoblock or thermocoil and the boiler must be of the right size.
It is also crucial to heat your machine as well as the portafilter and cup prior to making the espresso. Beginners often make the mistake of not preheating their machine. This is the reason why you should always go through the instruction manual prior to making use of your espresso maker for the first time.
Grind
A barista espresso machine must provide a variety grind settings for you to have the most control over your final cup of coffee. Some machines come with an analog gauge that looks cool and helps you to improve your brewing skills. Ideally, you should reach around nine bars of pressure and keep that throughout the brew cycle. While this machine does not hit that target, it is pretty close and will be able to serve you well.
Another wonderful feature of this machine is its built-in burr grinder. This is a great feature for those who are new to espresso because it will not require you to purchase a separate burr grinder. The stainless steel conical grinder features 18 settings, which range from "coarse to fine."

Water
Water can be a tricky thing to master. Finding the right balance is essential. If you're using too much, it could cause mineral deposits in your machine, while too small and you'll struggle to enjoy a satisfying cup of espresso.
The ideal espresso water has low alkalinity and hardness level. It is best to use a water filter which does not use chlorine and adds a small amount (TDS) of total dissolved substances that add calcium and magnesium. This will result in a good balance of alkalinity and hardness and avoid the need to decalcify your machine.
It is vital to use water filtered of high-quality for the health and taste of your machine. Depending on the use and hardness of your machine, you should make use of a descaling product regularly. They are available in liquid, powder or tab form at the majority of hardware stores.
