What to Look For in a Barista Espresso Machine
The espresso machine is among the most complex coffee machines on the planet. It is composed of three main components. The bottom holds the water while the middle part is a filter-basket with a filter made of metal.
This machine was a huge success and helped popularize the prosumer (home barista) espresso market. It features a low pressure pre-infusion and a 2.2L boiler and the brewing pressure of 9 bars.
Pressure
If you're serious about coffee then you're aware that the pressure of your espresso maker is an important aspect in how well your drinks turn out. You may be looking for a thick layer of crema, or the right balance of flavor and acidity the pressure of your espresso machine is the most important factor in brewing perfect espresso.
BARs (Barometric Pressure) refer to the amount of force applied to the coffee grounds when your espresso machine is delivering its high-pressure water. 9 BARs means that your espresso machine is forcing heated water through the ground coffee at a an amount of nine times the current atmospheric pressure.
The pressure of your espresso machine is crucial as it allows the water to move through the grounds of the coffee at the right speed and in the right amount. If the pressure is low the oils and flavors won't be extracted properly. On the other however, if the pressure is too high, the water will be pushed through the coffee grounds too quickly and you'll end up 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 appliances have rotary pumps with adjustable pressure. For the less expensive home machines that have a vibrating motor, it is impossible to alter the pressure with DIY hacks. However, companies like Cafflano are working on technology that uses Pascal's Principle to maintain pressure inside the portafilter throughout the brewing process.
Temperature
Temperature is one of the most important elements in the making of a good espresso shot. If the water is too hot, it can heat the coffee grounds and create a bitter espresso. The optimal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all the desired coffee flavors without burning the grounds or over-extracting.
The top espresso machines have a thermoblock or thermocoil which warms the water and keeps it at a steady temperature throughout the whole extraction process. The Breville Barista Express has a PID system (Proportional Integral Derived) which continuously monitors and adjusts the water temperature. This ensures that the brewhead remains at the right temperature for extraction.
Most coffee lovers know that the temperature of your espresso machine is a crucial factor in brewing a great cup of coffee. The ideal brewing temperature for espresso is between 190 and 196 degrees Fahrenheit.

Water can be a tricky thing to master. The trick is finding the optimal balance. Too much caffeine can cause mineral deposits to build up in your machine. However, too little will result in less of an espresso.
The ideal water for espresso is soft and high in alkalinity. This is best achieved by using a water filter system which bypasses all chlorine and adds back a small amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will ensure an ideal balance between hardness and acidity, and prevent the necessity of decalcifying.
Using a high quality filtered water is essential to your machine's longevity health and the flavor of the coffee it produces. Depending on the use and hardness of your machine you should use a descaling product regularly. The products are available in powder, liquid and tab forms and can be found in all hardware stores.
