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 components. The bottom holds the water, and the middle is a filtration basin with a metal filter.

This machine was a huge success and helped to popularize the prosumer (home barista) pro espresso machine market. It features a low pressure pre-infusion with a 2.2L boiler, and brewing pressure of 9 bar.

Pressure

If you're serious about your coffee then you're aware that the pressure of your electric espresso maker maker is a crucial factor in how well your drinks come out. Whether you're looking for an even layer of crema or perfect balance of flavor and acidity, the pressure of your espresso machine is essential to making excellent espresso.

BARs (Barometric pressure) is the amount of force that your espresso machine applies to the coffee and espresso machine grounds while delivering high-pressure water. 9 BARs indicates that your espresso machine is pushing heated water through the ground coffee at a the rate of nine times the current atmospheric pressure.

The pressure of your machine is vital because it allows water to flow through coffee grounds at the correct speed and intensity. If the pressure is too low, the flavors and oils dissolved 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 with a weak and over-extracted 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 machines have pumps with rotary that can be adjusted. For the cheaper home machines that use a vibrating motor, it is not possible to adjust the pressure without DIY hacks. However, companies like Cafflano are developing technology that utilizes Pascal's Principle to create maintained pressure within the portafilter during the fermentation process.

Temperature

Temperature is one of the most important aspects in a perfect espresso shot. Too hot water can burn the grounds of coffee, which can result in a bitter drink. The ideal extraction temperature is around 200 degrees Fahrenheit which allows the water to extract all the desirable coffee flavors without scorching the grounds or over-extracting.

The top espresso machines include a thermoblock or thermocoil that will heat the water, and keeps it at a stable temperature throughout the entire extraction cycle. The Breville Barista Express has a PID system (Proportional Integral Derived) which constantly monitors and adjusts the water temperature. This ensures that the brewhead is at the correct temperature for extraction.

Many coffee drinkers know that the temperature of your espresso machine is a crucial factor in brewing a great cup of coffee. The ideal temperature for espresso is between 190 and 196. In order to get this temperature, your machine must have a quality thermoblock or thermocoil, and the boiler should be sized appropriately.

It is also essential to pre-heat your espresso maker, portafilter and cup before making the espresso. Espresso makers who are beginners often make the mistake of not preheating their equipment. You should always read your espresso machine's manual before you try it for the very first time.

Grind

A barista espresso machine should provide a variety grind settings to give you the most control over the final cup of coffee. Some machines include an analog pressure gauge which looks cool and can help you gain knowledge about the brewing process. It is recommended to maintain the pressure of nine bars throughout the entire brewing process. This machine is getting close to hitting that target.

Another excellent feature of this machine is its built-in burr grinder. This feature is perfect for beginners since it eliminates having to purchase an additional grinder. The grinder is a stainless steel conical device with 18 settings, ranging from "coarse" to "fine."

The grinder isn't as effective as a standalone but it will get you going in the right direction to creating great espresso shots. It's easy to clean and you can pause it while grinding to avoid creating a mountain of grounds that spill over your portafilter while on its way to tamping.

This is a stunning and practical machine that allows you to experience the joy of being a barista at home. It's a great option for anyone who would like to to look back at the fond memories of pouring microfoam into their morning cup of joe, locking a portafilter into the grouphead, and then tamping with precision. For those who just want convenience, a bean to cup machine could be a better fit.

Water

Water can be a challenging thing to master. It's important to find the optimal balance. Too much can cause mineral deposits to develop in your machine. But too little will result in a weaker cup of espresso.

The ideal espresso water is soft and high in alkalinity. This is best achieved using a water filter 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 give you a good balance between acidity and hardness and avoid the need to decalcify.

It is vital to use water that is filtered and of excellent quality for the health and flavor of your machine. Based on the type of use and hardness of your machine you should make use of a descaling product on a regular basis. The products are available in tab, liquid or powder in a variety of hardware stores.

The Breville Barista Express is a high-end, luxury home espresso machine designed to bring the experience of a cafe into the home. It is equipped with more advanced features compared to other beginner machines, and is targeted at coffee lovers who want to refine their technique and perfect their art of coffee. The thermocoil heater, with an integrated PID controller, placed on the group head which is constantly heated which makes it simple to regulate your brewing temperature. This is a major advantage over other models at the entry level, which require lots of time "temperature-surfing" to achieve an even shot of espresso.
