It is made up of three major components. The bottom holds the water and the middle part is a filter-basket with a metal filter.
This machine was a huge success and was instrumental in establishing the prosumer (home barista) espresso and filter coffee machine market. Features include a 2.2L steam boiler, low pressure pre-infusion & 9 bar pressure for brewing.
Pressure
If you're serious about your coffee and espresso, then you're aware that the pressure of your espresso machine is an important factor in how well your drinks come out. The pressure of your machine is essential in brewing excellent coffee whether you're looking for a thick layer or the perfect balance of acidity and flavor.
BARs (Barometric pressure) is the force your espresso machine exerts upon the grounds of coffee while pumping high-pressure water. Your espresso machine is pushing heated water through the grounds of your coffee at nine times that of Earth's current atmosphere pressure.
The pressure of your machine is important because it allows water to move through coffee grounds at a proper speed and intensity. If the pressure is low the flavors and oils 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 up with an over-extracted, weak cup of espresso.
The pressure of your espresso machine can be adjusted by turning the screw on the espresso pump. Commercial and high-end home machines have rotary pumps with adjustable pressure. For the cheaper home appliances that utilize a vibrating pump, adjusting the pressure is impossible without involving DIY hacks. Companies like Cafflano, however, are working on technology that uses Pascal's Principle to ensure the pressure within the portafilter all through the beer making process.
Temperature
Temperature is one of the most important factors in the perfect 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 best espresso machines include a thermoblock or thermocoil which heats the water and keeps it at a steady temperature throughout the whole extraction process. The Breville Barista Express, for instance, comes with a PID (Proportional Integral Derivative) system that constantly monitors the temperature of water and adjusts it as needed making sure that the brewhead stays at a perfect temperature to extract the coffee.
Most coffee lovers know that the temperature of the espresso maker is vital to brewing a great cup of coffee. The ideal temperature for espresso is between between 190 and 196 degrees. To achieve this, you need a machine with a good thermoblock, thermocoil and a boiler that is properly sized.
It is also essential to pre-heat your machine or portafilter before making a shot. Beginners often make the mistake of not preheating their machine. Always read the espresso machine's instruction manual before you use it for the first time.
Grind
A barista machine must give you a range of grind settings so you can have the most control over the final cup of espresso. Some machines include an analog gauge which looks cool and aids you develop your brewing capabilities. In the ideal scenario, you'll want to get around nine bars of pressure and maintain that throughout the brewing cycle. This machine is very close to reaching that goal.
Another excellent feature of this machine is its built-in burr grinder. This is a wonderful feature for those who are new to espresso because it will not require you to pay for a separate burr grinder. The grinder is a conical stainless steel unit with 18 settings from “coarse” to “fine.”
This grinder isn't as powerful as a standalone but it will get you going in the right direction to making excellent professional espresso machine for home shots. It's easy to clean, and you can pause the grinder during the process of grinding to avoid accumulating a huge amount of grounds in your portafilter when it is being tamped.
This beautiful and functional machine will allow you to enjoy the barista experience in your own home. This is a great choice for anyone who wants to relive the excitement of pouring microfoam in their morning cup of coffee while locking the portafilter in the head of the grouphead and then tamping with precision. For those who just want convenience, a bean-to- cup machine might be a better fit.
Water
Water is a tricky thing to master. The key is to find the proper balance. Too much caffeine can cause mineral deposits to build up in the machine, but too small and you'll struggle to make a full cup of espresso.
The best espresso water has the lowest alkalinity and hardness level. This is best achieved using an effective water filtering system that eliminates chlorine and brings back in a small amount of total dissolved solids (TDS) to add some calcium and magnesium to the mix. This will result in a balanced balance of alkalinity and hardness, and will avoid the necessity to decalcify your equipment.
Using a high quality espresso machine filtered water is essential to your machine's longevity health and the taste of the coffee it makes. Descaling products must be used on a regular basis, depending on the strength and use of your machine. These products are available in powder, liquid and tab forms and are available in all hardware stores.

It is equipped with more advanced features than other beginner machines, and is designed for coffee for espresso machine enthusiasts who wish to improve their technique and master the craft. The thermocoil heating technology with a built-in PID controller centered on the actively heated group head makes it easy to regulate your brewing temperature. This is an enormous advantage over other entry-level models that require longer “temperature surfing” to achieve an espresso shot that is consistent.
