What to Look For in a Barista Espresso Machine
The espresso machine is among the most intricate coffee machines on the planet. It is composed of three main parts. The bottom holds the water and the middle is a filtration basin with a metal filter.
This machine was a big hit and helped popularize the home barista espresso. Features include a 2.2L steam boiler, low pressure pre-infusion, and 9 bar pressure for brewing.
Pressure
If you're an avid coffee drinker, then you will know that the pressure of your machine is a key factor in the quality of your beverages. It doesn't matter if you're seeking an even layer of crema, or the perfect balance of flavor and acidity, the pressure of your espresso machine is essential to making excellent espresso.
BARs (Barometric Pressure) refer to the force that is imposed on the coffee grounds when your espresso machine is delivering its high-pressure water. 9 BARs indicates that your espresso machine is forcing heated water through the ground coffee at a 9 times the Earth's current atmospheric pressure.
The pressure of your machine is important because it allows the water to pass through coffee grounds at the correct speed and intensity. If the pressure isn't sufficient the oils and flavors aren't extracted properly. On the other hand, if the pressure is too high the water will be pushed through the coffee grounds too fast and you'll end with a weak, diluted cup of espresso.
The pressure of your espresso machine can be adjusted by turning the screw found on the espresso pump. Commercial machines as well as some high-end home appliances use rotary pumps that are adjustable. However, for the less expensive home machines that utilize the vibrating pump, altering the pressure is impossible without engaging in DIY hacks. However, companies like Cafflano are developing technology that utilizes Pascal's Principle to maintain pressure within the portafilter during the fermentation process.
Temperature
Temperature is one of the most important elements in a great espresso shot. Too hot water can burn the coffee grounds, resulting in a bitter coffee. The optimal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all desired coffee flavors without burning the grounds or excessively extracting.
The best espresso machines feature the thermoblock, also known as a thermocoil which heats the water and keeps it at an unchanging temperature throughout the extraction process. The Breville Barista Express, for instance, is equipped with a PID (Proportional Integral Derivative) system which constantly monitors the temperature of the water and adjusts as necessary making sure that the brewhead remains at a perfect temperature for extraction.
The majority of coffee drinkers know that the temperature of the espresso machine is crucial to a good cup of coffee. The ideal temperature for espresso is between between 190 and 196 degrees. To achieve this, you need an espresso machine with a top thermoblock, thermocoil and boiler that is correctly sized.
In addition, it's important to preheat your espresso maker, portafilter and cup before you make the shot. Beginner espresso makers often make the mistake of not preheating their machines. It is recommended to read your espresso machine's instruction manual before you begin using it for the first time.
Grind
A barista espresso machine must provide a variety grind settings to give you the greatest control over your final cup of coffee. Some machines include an analog pressure gauge that is stylish and can help you gain knowledge about your brewing techniques. You should aim to maintain the pressure of nine bars throughout the entire brewing process. This machine is near reaching that goal.
Another great feature of this machine is that it has a built-in burr grinder. This is a wonderful feature for people who are new to espresso since it will not require you to purchase a separate burr grinder. The grinder is a conical stainless steel unit with 18 settings ranging from "coarse" to "fine."
The grinder isn't as good as a stand-alone unit, however, it's a decent start and will put you on the right track to making quality 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 while it's being put through the tamper.

It's an excellent choice for those who want to be able to look back on the memories of pouring microfoam into their morning coffee by locking a portafilter to the grouphead, and tamping with precision. For those who simply want convenience, a bean-to- cup machine might be a better choice.
Water
Water can be a challenging thing to master. Finding the right balance is key. Too much caffeine can cause mineral deposits to form in your machine, while too little and you'll struggle get a rich cup of espresso.
The ideal espresso water is soft and high in alkalinity. It is best to use a water filter that bypasses chlorine and adds a tiny amount (TDS) of total dissolved substances that add calcium and magnesium. This will result in an ideal balance of alkalinity as well as hardness. It will also avoid the necessity to decalcify your equipment.
A high-quality, filtered water is vital for your machine's long-term health as well as the flavor of the coffee it produces. Depending on the use and the hardness of the machine, you should use descaling products on a regular schedule. They are available in powder, liquid and tab forms and can be found in the majority of hardware stores.
