What to Look For in a Barista Espresso Machine
The espresso machine is among the most intricate coffee machines around the world. It is comprised of three major components. The base holds the water and the middle is a filtration basin with a filter made of metal.
This machine was a huge hit and was instrumental in establishing the prosumer (home barista) espresso market. It features a 2.2L steam boiler, low pressure pre-infusion and 9 bar brewing pressure.
Pressure
If you're serious about your coffee then you're aware that the pressure of your espresso maker is an important aspect in how well your drinks are made. The pressure of your machine is essential in brewing excellent coffee whether you're looking for a thick layer or the perfect balance of flavor and acidity.
BARs (Barometric pressure) is the amount of force that your espresso machine exerts on grounds of your coffee while delivering high-pressure water. Your espresso machine is pushing heated water through the grounds of coffee at nine times Earth's current atmosphere pressure.
The pressure of your machine is vital because it allows the water to pass through coffee grounds at a proper speed and intensity. If the pressure isn't sufficient, the oils and flavors will not be extracted properly. If the pressure is too low the dissolved flavors and oils will not be extracted correctly.
The pressure of your espresso machine can be adjusted by turning the screw that is located on the espresso pump. Commercial machines and top-end home machines come with rotating pumps that can be adjusted in pressure. For the cheaper home machines that have an oscillating pump, changing the pressure is impossible without involving DIY hacks. However, companies such as Cafflano are developing technology that utilizes Pascal's Principle to maintain pressure inside the portafilter during the fermentation process.
Temperature
Temperature is one of the most important factors in a perfect espresso shot. A hot water can burn the grounds of the coffee, resulting in bitter espresso. The ideal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all of the desired coffee flavors without burning the grounds or over-extracting.
The best espresso machines will feature a thermoblock, or thermocoil which is used to heat the water and keep it at a constant temperature throughout the entire extraction process. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system which constantly monitors the temperature of the water and adjusts as necessary to ensure that the brew head remains at the perfect temperature to extract the coffee.
Most coffee lovers know that the temperature of the espresso maker is vital to brewing a great cup of coffee. The ideal temperature for brewing espresso is between 190 and 196 degrees Fahrenheit. To attain this, you will require a machine with a good thermoblock, thermocoil, and a boiler that is properly sized.
It is also crucial to heat up your machine, portafilter and cup before making the espresso. Espresso makers who are beginners often make the mistake of not preheating their equipment. It is advisable to read your espresso machine's manual prior to attempting to start using it for the first time.
Grind
A barista espresso machine should provide a variety grind settings to give you the greatest control over the final cup of coffee. Some machines include an analog pressure gauge which is cool and can help you learn about your brewing abilities. You should strive to maintain the pressure at nine bars throughout the brewing process. This machine is very close to hitting that target.
Another wonderful feature of this machine is that it has a built-in burr grinder. This is a wonderful feature for those who are new to espresso because it eliminates the need to purchase a separate burr grinder. The stainless steel conical grinder features 18 settings, which range from "coarse to fine."
This grinder isn't as powerful as a standalone but it can help you get to the right path to creating great espresso shots. It's easy-to-clean and you can stop the grinder in the process of grinding to avoid creating a mountainous amount of grounds on your portafilter as it is being stamped.
This beautiful and functional machine will allow you to experience being a barista in your home. This is an excellent choice for those who want to remember the thrill of pouring microfoam in their morning coffee while locking the portafilter in the head of the grouphead and tamping the coffee with precision. For those who just want convenience, a bean to cup machine might be a better option.
Water
It is a challenge to master. Finding the right balance is crucial. Too much can cause mineral deposits in your machine, however too little and you'll struggle to enjoy a satisfying cup of espresso.
The best espresso water has an alkalinity and hardness that is low level. It is best to use a filter which does not use chlorine and adds a tiny amount (TDS) of total dissolved substances in order to add calcium and magnesium. This will result in an optimal balance between alkalinity and hardness and prevent the necessity of decalcifying your equipment.
It is important to make sure you use water that has been filtered to a high quality for the health and taste of your machine. Based on the usage and the hardness of your machine, you should use a descaling product on a regular basis. These products are available as tab, liquid, or powder form at the majority of hardware stores.

It has more advanced features when compared to other machines for beginners and is designed for coffee lovers who want to refine their technique and perfect the art of coffee. The thermocoil heater that has an integrated PID controller placed on the group head that is constantly heated which makes it simple to regulate your brewing temperatures. This is a major benefit over other models that require longer "temperature surfing" to ensure an espresso shot that is consistent.
