What to Look For in a Barista Espresso Machine
The espresso machine is among the most intricate coffee machines around the globe. It consists of three main parts. The bottom holds the water while the middle is a filter-basket with a metal filter.
This machine was a huge success and helped to popularize the prosumer (home barista) cheap espresso machine market. It features a low pressure pre-infusion with a 2.2L boiler and brewing pressure of 9 bar.
Pressure
If you are an avid coffee drinker, then you’ll know that the pressure of your machine is a crucial element in the quality of your coffee. If you’re looking for an even layer of crema or the right balance of acidity and flavor, the pressure of your espresso machine is the key to brewing perfect espresso.
BARs (Barometric Pressure) refer to the force that is applied to the coffee grounds when your espresso machine is pumping out its high-pressure water. Your espresso machine is pushing hot water through the grounds of your coffee at nine times the current atmospheric pressure.
The pressure of your machine is essential because it allows water to flow through coffee grounds at the proper speed and intensity. If the pressure isn’t high enough the oils and flavors will not be extracted correctly. On the other contrary, if pressure is too high, the water will be forced 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 controlled by adjusting the screw on the espresso pump. Commercial and high-end home machines come with rotating pumps that can be adjusted in pressure. For the more affordable home machines that have a vibrating pump, adjusting the pressure is difficult without getting into DIY hacks. Companies like Cafflano however, are developing technology that uses Pascal’s Principle to ensure pressure in the portafilter during the brewing process.
Temperature
The temperature is one of the most important factors in brewing the perfect espresso machine coffee shot. The water that is too hot can scorch the grounds of the coffee, leading to a bitter drink. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all of the desired coffee flavors without burning the grounds or causing excessive extraction.
The best espresso machines will feature a thermoblock, or thermocoil that heats the water and keeps it at a steady temperature throughout the entire extraction process. The Breville Barista Express, for example, features PID (Proportional Integral Derivative) system which constantly checks the temperature of the water and adjusts if needed to ensure that the brewhead stays at the ideal temperature for extraction.
Many coffee drinkers are aware that the temperature of the espresso coffee makers machine is crucial to a good cup of coffee. The ideal temperature for espresso is between between 190 and 196 degrees. To get this temperature, your machine must have a good thermoblock or thermocoil, and the boiler should be sized to the correct size.
Additionally, it is important to preheat your portafilter, espresso machine, and the cup prior to making a shot. Inability to heat your equipment is among the most frequent errors made by novice espresso makers. It is advisable to read your espresso machine’s instruction manual before you use it for the first time.
Grind
A barista espresso machine should provide a variety grind settings for you to have the most control over your final cup of coffee. Some machines include an analog gauge that looks cool and can help you develop your brewing capabilities. You should strive to maintain a pressure of nine bars throughout the process of brewing. Although this machine can’t reach that target, it is quite close and will serve you well.
A built-in burr mill is a excellent feature. This feature is great for beginners since it eliminates the need to purchase an additional grinder. The grinder is a stainless steel conical device with 18 settings from “coarse” to “fine.”
It’s not as efficient as a stand-alone device, but it can get you started on the path to creating great espresso shots. It’s easy to clean and you’ll be able to stop the grinder during the process of grinding to prevent accumulating a large amount of grounds in your portafilter when it’s being put through the tamper.
It’s a beautiful and practical machine that will allow you to feel the excitement of being a barista home. It’s an excellent choice for anyone who would like to be able to look back on the memories of pouring microfoam into your morning cup of coffee and locking a portafilter in the grouphead, and tamping with precision.

Water
Water can be a challenging thing to master. Finding the right balance is key. If you’re using too much, it could cause mineral deposits to build up in your machine, however too little and you’ll struggle to get a rich cup of espresso.
The ideal espresso water has a low hardness and alkalinity level. It is recommended to use a water purifier that bypasses 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 need to decalcify your machine.
It is crucial to use water that is filtered and of excellent quality for the health and flavor of your machine. Descaling products must be utilized on a regular basis based on the hardness and use of your machine. These products come in powder, liquid and tab forms and are available in all hardware stores.
