What to Look For in a Barista Espresso Machine

The espresso machine is one of the most complicated coffee machines around the globe. It consists of three main parts. The bottom holds the water, and the middle is a filter-basket with a metal filter.

This machine was a huge hit and helped spread the prosumer (home barista) espresso machine with frother market. It features a low pressure pre-infusion as well as an 2.2L dual boiler espresso machine, and the brewing pressure of 9 bars.

Pressure

If you're an avid coffee drinker, you'll be aware that the pressure of your espresso machine is a key element in the quality of your drinks. The pressure of your machine is vital in brewing excellent coffee whether you're seeking a thick layer or a perfect balance of flavor and acidity.

BARs (Barometric pressure) is the force your espresso machine exerts upon the grounds of your coffee while delivering high-pressure water. Your espresso machine is pushing hot water through the grounds of the coffee at a rate nine times the current atmospheric pressure.

The pressure of the espresso machine is crucial because it allows water to flow through the grounds of your coffee with the right speed and with the right intensity. If the pressure isn't sufficient, the oils and flavors will not be extracted correctly. If the pressure is too low the dissolved oils and flavors will not be extracted properly.

You can control the pressure of your espresso maker by adjusting the screw on the espresso pump. Commercial machines and a few high-end home appliances use rotating pumps that can be adjusted. For home-based machines that use a vibrating motor, it's not possible to adjust the pressure with DIY hacks. However, companies such as Cafflano are working on technology that makes use of Pascal's Principle to maintain pressure within the portafilter during the brewing process.

Temperature

The temperature is among the most important factors in brewing an espresso shot that is perfect. A hot water can burn the coffee grounds, resulting in a bitter espresso. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all of the desired coffee flavors without scorching the grounds or over-extracting.

The top espresso machines include a thermoblock which will heat the water, and keeps it at a steady temperature throughout the entire extraction process. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system which constantly monitors the water temperature and adjusts according to the need making sure that the brew head remains at the ideal temperature for extraction.

Many coffee enthusiasts know that the temperature of your espresso machine is a key factor in making a quality cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190-196. In order to achieve this, your espresso machine must be equipped with a reliable thermoblock or thermocoil and the boiler must be of the right size.

It is also crucial to heat your machine, portafilter and cup before making the espresso. Espresso makers who are beginners often make the mistake of not heating their machine prior to making a shot. It is recommended to read your espresso machine's manual before you begin using it for the first time.

Grind

A barista espresso machine should also have a variety of grind settings to give you the most control over your final cup of coffee. Some machines include an analog pressure gauge, which is cool and can help you gain knowledge about your brewing techniques. The goal is to maintain the pressure at nine bars throughout the entire brewing process. This machine is very close to getting to that point.

Another excellent feature of this machine is the built-in burr grinder. This feature is ideal for those who are new to the field because it avoids having to buy espresso machines an additional grinder. The stainless steel conical grinder comes with 18 settings, ranging from "coarse to fine."

It's not as efficient as a standalone but it will get you started on the path to making great espresso shots. It's easy to clean and you can stop the grinder during the process of grinding to prevent accumulating a large amount of ground on your portafilter as it's being put through the tamper.

This stunning and practical machine lets you enjoy the barista experience in your home. It's a great option for those who want to be able to revisit the fond memories of pouring microfoam into their morning coffee by locking a portafilter to the grouphead, and then tamping with precision. A bean-to-cup machine is a good option for those looking for a simple and convenient solution.

Water

Water can be a difficult thing to master. Finding the right balance is key. If you're using too much, it could result in mineral deposits on your machine, however too little and you'll struggle get a rich cup of espresso.

The perfect water for espresso is low in hardness and high in alkalinity. It is recommended to use a filter which does not use chlorine and adds a tiny amount (TDS) of total dissolved substances to add calcium and magnesium. This will give you the right balance between acidity and hardness and avoid the necessity of decalcifying.

It is vital to make sure you use water that has been filtered to a good quality to ensure the health and flavor of your machine. Descaling products should be used on a regular basis, depending on the strength and use of your machine. These products are available in liquid, powder or tab form at the majority of hardware stores.

The Breville Barista Express, a premium espresso machine for home use, is designed to bring the café experience into your home. It is equipped with more advanced features than other machines for beginners and is geared towards those who are looking to refine their technique and perfect the art of coffee. The thermocoil heater, with an integrated PID controller, centered on the group head which is actively heated, makes it easy to regulate your brewing temperature. This is a major advantage over the other models that require you to spend longer "temperature surfing" to ensure an espresso shot that is consistent.
