What to Look For in a Barista Espresso Machine
The espresso machine is one of the most complex coffee machines around the world. It is comprised of three main components. The bottom holds the water while the middle part is a filter-basket with a filter made of metal.
This machine was a huge hit and helped spread the prosumer (home barista) espresso market. It features a 2.2L steam boiler, a low pressure pre-infusion & 9 bar brewing pressure.
Pressure
If you're a coffee enthusiast, you will know that the pressure of your machine is a key element in the quality of your drink. Whether you're looking for an even layer of crema, or the right balance of acidity and flavor The pressure of your espresso machine is crucial to making great espresso.
BARs (Barometric Pressure) refer to the amount of force exerted on the coffee grounds when your espresso machine is delivering its high-pressure water. 9 BARs means that your espresso machine is pushing heated water through the ground coffee at a 9 times the Earth's current atmospheric pressure.
The pressure of your espresso machine is crucial as it allows the water to flow through the grounds of the coffee at the right speed and with the right intensity. If the pressure is too low the dissolved oils and flavors will not be extracted properly. On the other hand, if the pressure is too high, the water will be forced through the coffee grounds too fast and you'll end with an over-extracted, weak cup of espresso.
You can control the pressure of your espresso maker by adjusting the screw that is attached to the espresso pump. Commercial machines as well as some high-end home machines have pumps with rotary that can be adjusted. For the cheaper home machines that have a vibrating motor, it's not possible to alter the pressure without DIY hacks. However, companies like Cafflano are working on technology that uses Pascal's Principle to create maintained pressure in the portafilter during the brewing process.
Temperature
The temperature is one of the most crucial factors to a great espresso shot. If the water is too hot, it may ignite the coffee grounds and produce an over-extracted bitter drink. The ideal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all the desired coffee flavors without burning the grounds or causing excessive extraction.
The best espresso machines include a thermoblock, or thermocoil, which heats water and keeps it at an unchanging temperature throughout the extraction process. The Breville Barista Express, for instance, comes with a PID (Proportional Integral Derivative) system that constantly monitors the water temperature and adjusts if needed to ensure that the brew head remains at the perfect temperature for extraction.
Many coffee drinkers are aware that the temperature of the espresso machine is essential to making a great cup of coffee. The ideal temperature for espresso is between between 190 and 196 degrees. To achieve this, your machine should have a high-quality thermoblock or thermocoil and the boiler needs to be sized appropriately.
In addition, it's important to pre-heat your espresso maker, portafilter and the cup prior to making an espresso. Inability to heat your equipment is one of the most common mistakes that can be made by beginners to making espresso. This is the reason you should always read the instruction manual before using your espresso machine for the first time.
Grind
A barista espresso machine must also have a variety of grind settings to give you the greatest control over the final cup of coffee. Some machines have an analog pressure gauge which is cool and can help you gain knowledge about your brewing skills. Ideally, you want to achieve around nine bars of pressure and maintain that throughout the brewing cycle. This machine is close to the goal.
Another excellent feature of this machine is that it has a built-in burr grinder. This feature is ideal for novices because it doesn't mean having to buy a separate grinder. The grinder is a conical stainless steel device with 18 settings ranging from "coarse" to "fine."
This grinder isn't quite as effective as a standalone unit, but it's an excellent start and will have you well on your way to creating quality espresso shots. It's easy to clean, and you can also pause it during the grinding process, which helps you avoid making a mountain of grounds that spill over your portafilter while on its way to tamping.
This gorgeous and useful machine lets you experience being a barista in your own home. It's an excellent choice for those who best coffee espresso machine wish to to look back at the moments of pouring microfoam into their morning coffee, locking a portafilter into the grouphead, and then tamping with precision. For those who want convenience, a bean-to- cup machine might be a better fit.
Water
Water is a challenging thing to master. Finding the right balance is crucial. If you're using too much, it could cause mineral deposits to build up in your machine, while too small and you'll struggle to get a rich cup of espresso.
The ideal water for espresso has the lowest alkalinity and hardness level. This is best accomplished by using an effective water filtering system that bypasses all chlorine and adds an amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will result in a good balance of alkalinity as well as hardness. It will also prevent the need to decalcify your machine.
It is vital to use water that is filtered and of high-quality for the health and taste of your machine. Based on the type of use and hardness of your machine you should use descaling products regularly. They are available in liquid, powder and tab forms and can be found at the majority of hardware stores.

It is equipped with more advanced features compared to other beginner machines, and is designed for coffee enthusiasts who want refine their technique and perfect their art of coffee. The thermocoil heating technology with a built-in PID controller centered on the group head makes it easy to regulate your brewing temperature. This is a major advantage over other entry-level models that require you to spend more time "temperature surfing" to get an even shot of espresso.
