The 10 Most Terrifying Things About Barista Espresso Machine
What to Look For in a Barista Espresso Machine
The espresso machine is one of the most complex coffee machines in the world. It is comprised of three major components. The bottom is where the water goes and the middle contains the filter-basket.
This machine was a huge success and helped to popularize home barista espresso. Features include a low pressure pre-infusion and a 2.2L boiler, and brewing pressure of 9 bar.
Pressure
If you're serious about your coffee, then you know the pressure of your espresso maker is an important aspect in how well your drinks come out. Whether you're looking for a thick layer of crema, or the right balance of flavor and acidity The pressure of your espresso maker is crucial to making perfect espresso.
BARs (Barometric pressure) is the amount of force that your espresso machine applies to the coffee grounds while delivering high-pressure water. 9 BARs mean that your espresso machine is pushing heated water through the coffee grounds at a rate of nine times the current atmospheric pressure.
The pressure of your espresso machine is vital 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 is too low the dissolved oils and flavors won't be extracted properly. On the other hand, if the pressure is too high, the water will be forced through the coffee grounds too fast 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 located on the espresso pump. Commercial and high-end home machines feature rotary pumps with adjustable pressure. However, for the less expensive home machines that use the pump that vibrates, adjusting the pressure is impossible without involving DIY hacks. However, companies such as Cafflano are developing technology that makes use of Pascal's Principle to maintain pressure inside the portafilter during the making process.
Temperature
Temperature is among the most crucial factors in the making of a good espresso shot. If the water is too hot, it may ignite the coffee grounds and create a bitter drink. The optimal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all the desired coffee flavors without burning the grounds or over-extracting.
The best espresso machine under 200 espresso machines will include a thermoblock which heats the water and keeps it at a steady temperature throughout the whole extraction process. The Breville Barista Express, for example, features a PID (Proportional Integral Derivative) system that continuously checks the temperature of the water and adjusts if needed making sure that the brew head remains at the ideal temperature to extract the coffee.

The ideal temperature for brewing espresso is between 190 and 196 degrees Fahrenheit. To get this temperature, your machine must be equipped with a reliable thermoblock or thermocoil and the boiler must be sized appropriately.

A barista machine should give you a range of grind settings to ensure that you have the maximum control over your final cup of espresso. Some machines come with an analog pressure gauge which looks cool and can help you gain knowledge about the brewing process. The goal is to maintain an average pressure of nine bars throughout the brewing cycle. This machine is near reaching that goal.
Another wonderful feature of this machine is that it has a built-in burr grinder. This feature is perfect for beginners since it eliminates the need for an additional grinder. The grinder is a conical stainless steel unit with 18 settings ranging from "coarse" to "fine."
