What to Look For in a Barista Espresso Machine

The espresso machine is one of the most complicated coffee machines in the world. It is comprised of three major components. The bottom holds the water, and the middle part is a filter-basket with a filter made of metal.

This machine was a huge success and helped spread the prosumer (home barista) espresso market. Features include a low pressure pre-infusion with an 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 machine is an important aspect in how well your drinks taste. Whether you're looking for an even layer of crema, or the right balance of flavor and acidity, the pressure of your espresso machine is the most important factor in brewing excellent espresso.

BARs (Barometric Pressure) refer to the force applied to the grounds of your coffee when your espresso machine is pumping out its high-pressure water. Your espresso machine is pushing hot water through the coffee grounds at a rate nine times the Earth's current atmospheric pressure.

The pressure of your machine is essential because it allows water to flow through coffee grounds at a proper speed and intensity. If the pressure isn't sufficient the flavors and oils will not be extracted properly. On the other contrary, if pressure is too high the water will be forced through the coffee grounds too fast and you'll end up with a weak, over-extracted cup of espresso.

You can regulate the pressure of your professional espresso maker maker by changing the screw that is attached to the espresso pump. Commercial machines and a few high-end home machines have the rotary pumps, which are adjustable. For the more affordable home machines that utilize an oscillating pump, changing the pressure is difficult without engaging in DIY hacks. However, companies like Cafflano are working on technology that makes use of Pascal's Principle to create maintained pressure inside the portafilter throughout the brewing process.

Temperature

Temperature is among the most crucial factors in a great espresso shot. Too hot water can burn the grounds of the coffee, leading to bitter brew. The ideal extraction temperature is 200 degrees Fahrenheit which allows the water to extract all of the desirable coffee flavors without scorching the grounds, or over-extracting.

The best espresso machines feature a thermoblock, or thermocoil which warms the water and keeps it at a constant temperature throughout the entire extraction cycle. The Breville Barista Express has a PID system (Proportional Integral Derived) which continuously monitors and adjusts the temperature of the water. This ensures that the brewhead stays at the right temperature for extraction.

Many coffee drinkers are aware that the temperature of the espresso machine is essential to making a great cup of coffee machines espresso. The ideal temperature for espresso is between 190 and 196. In order to achieve this, your machine must have a quality thermoblock or thermocoil and the boiler must be of the right size.

Additionally, it is important to preheat your espresso maker, portafilter and cup prior to taking the shot. The failure to preheat is among the most frequent errors made by novice espresso makers. This is why it is important to always study the instruction manual before making espresso for the first time.

Grind

A barista machine should offer you a variety of grind settings so you can have the greatest control over the final cup of espresso. Some machines have an analog gauge which looks cool and aids you develop your brewing capabilities. In the ideal scenario, you'll want to achieve around nine bars of pressure and keep that throughout the brewing cycle. This machine is close to hitting that target.

Another nice touch on this machine is a built-in burr grinder. This is a fantastic feature for people who are new to espresso since it eliminates the need to buy an additional burr grinder. The grinder is an stainless steel conical unit that has 18 settings from "coarse" to "fine."

This grinder isn't as powerful as a standalone, but it's a good start and will get you on the path to brewing quality espresso shots. It's easy to clean and you can even pause it while grinding this will help you avoid making a mountain of ground that will fall all over your portafilter on its way to the tamping.

This gorgeous and useful machine will allow you to experience being a barista in your own home. It's a great option for anyone who would like to to revisit the memories of pouring the microfoam into their morning cup of joe and locking a portafilter in the grouphead, and tamping with precision. A bean-to-cup machine is a great choice for those who are looking for convenience.

Water

Water can be a tricky thing to master. The trick is to find the right balance. Too much caffeine can cause mineral deposits to form inside your machine. However, too little will result in less of an espresso.

The perfect espresso water has low alkalinity and hardness level. It is recommended to use a filter that bypasses chlorine and adds a tiny amount (TDS) of total dissolved substances that add calcium and magnesium. This will ensure an ideal balance between hardness and acidity, and prevent the need to decalcify.

It is important to use water that is filtered and of high-quality for the health and flavor of your machine. Based on the type of use and the hardness of the machine, you should make use of a descaling product regularly. They are available in liquid, powder and tab forms and are available at most hardware stores.

It comes with more advanced features compared to other espresso machines that are beginner-friendly, and is targeted at those who are looking to refine their technique and master the craft. The thermocoil heating mechanism with an integrated PID controller mounted on the actively heated group head makes it easy to control your brewing temperature. This is a huge benefit over other models that are entry-level which need you to spend lots of time "temperature-surfing" to ensure an even espresso shot.
