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 main parts. The bottom holds the water while the middle part is a filter-basket with a metal filter.

This machine was a huge hit and helped to popularize the prosumer (home barista) espresso market. Features include a low pressure pre-infusion as well as the 2.2L boiler and the brewing pressure of 9 bars.

Pressure

If you're serious about your coffee and espresso, then you're aware that the pressure of your espresso maker is an important factor in how your drinks turn out. The pressure of your machine is crucial to brewing great coffee, whether you're looking for a dense layer or the perfect balance of acidity and flavor.

BARs (Barometric pressure) is the force your espresso machine applies to the grounds of your coffee while delivering high-pressure water. The espresso machine is pushing heated water through the coffee grounds at a rate nine times Earth's current atmosphere pressure.

The pressure of your espresso machine is crucial because it allows the water to pass through the grounds of your coffee with the right speed and with the right intensity. If the pressure is low the flavors and oils will not 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 with an over-extracted, weak cup of espresso.

The pressure of your espresso machine can be adjusted by turning the screw found on the espresso pump. Commercial machines and some high-end home appliances have rotary pumps that are adjustable. But for the more affordable home machines that have a vibrating pump, adjusting the pressure is impossible without using DIY hacks. Companies such as Cafflano however, are developing technology that utilizes Pascal's Principle to ensure the pressure inside the portafilter throughout the fermentation process.

Temperature

Temperature is one of the most important factors in a perfect espresso shot. Too hot water can burn the grounds of the coffee, resulting in bitter brew. The ideal temperature for extraction is 200 degrees Fahrenheit, which allows the water to extract all the coffee's desirable flavors without burning the grounds or over-extracting.

The best home espresso machine espresso machines have a thermoblock or thermocoil that warms the water and keeps it at a stable temperature throughout the whole extraction cycle. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system that continuously monitors the temperature of water and adjusts it as needed, ensuring that the brewhead stays at the right temperature for extraction.

Many coffee enthusiasts know that the temperature of your espresso maker is a crucial factor to brewing a high-quality cup of coffee. The ideal temperature for brewing espresso is between 190 to 196 degrees Fahrenheit. To achieve this, you need an espresso machine that has a high-quality thermoblock, thermocoil and a boiler that is correctly sized.

It is also crucial to warm your machine, portafilter, and the cup prior to making a shot. Beginner espresso makers often make the mistake of not heating their machine prior to making a shot. This is why you should always study the instruction manual before making espresso for the first time.

Grind

A barista espresso machine must also offer a variety of grind settings to give you the most control over your final cup of coffee. Some machines include an analog gauge which looks cool and aids you improve your brewing skills. Ideally, you should reach around nine bars of pressure, and keep that throughout the brew cycle. This machine is getting close to reaching that goal.

Another nice touch on this machine is its built-in burr grinder. This feature is great for beginners since it eliminates the need for a separate grinder. The stainless steel conical grinder has 18 settings, ranging from "coarse to fine."

This grinder isn't as good as a standalone unit, but it's a solid start and will put you on the right track to creating quality espresso shots. It's easy to clean and you can also pause it during the grinding process and avoid creating a mountain of ground that will fall across your portafilter as it makes its way to the tamping.

This beautiful and functional machine will allow you to feel like a barista from your own home. It's an excellent choice for those who want to to revisit the fond memories of pouring microfoam into their morning cup of joe, locking a portafilter into the grouphead, and tamping with precision. For those who just want convenience, a bean to cup machine might be a better fit.

Water

Water can be a tricky thing to master. Finding the right balance is key. Too much and it can cause mineral deposits to form in the machine, but too little and you'll struggle to get a good cup of espresso.

The ideal espresso water has a low hardness and alkalinity level. It is recommended to use a water purifier that removes chlorine and adds a small amount (TDS) of total dissolved substances to add calcium and magnesium. This will create an ideal balance of hardness and alkalinity and will prevent the necessity of decalcifying your machine.

Using a high quality espresso machine filtered water is essential to your machine's long term health as well as the taste of the coffee it makes. Depending on the use and hardness of your machine, you should make use of descaling products on a regular basis. These products are available in tab, liquid, or powder in a variety of hardware stores.
