What to Look For in a Barista Espresso Machine

This machine was a major success and was instrumental in bringing home Salter EK4369 Barista Pro Espresso Maker 15Bar espresso. It features a 2.2L steam boiler, low pressure pre-infusion, and 9 bar brewing pressure.

Pressure

If you're serious about coffee, then you know the pressure of your espresso machine is an essential factor in how your drinks come out. The pressure of your machine is essential for making great coffee, whether you're seeking a thick layer or a perfect balance of acidity and flavor.

BARs (Barometric Pressure) refer to the amount of force that is imposed on the grounds of your coffee when your espresso machine is delivering its high-pressure water. The espresso machine is pushing heated water through the coffee grounds at a rate nine times the Earth's current atmospheric pressure.

The pressure of your machine is vital because it allows the water to flow through coffee grounds at the proper speed and intensity. If the pressure is too low the dissolved oils and flavors aren't extracted properly. If the pressure is too low, the flavors and oils dissolved will not be extracted properly.

The pressure of your espresso machine can be adjusted by turning the screw on the espresso pump. Commercial and high-end home machines come with the rotary pumps that have adjustable pressure. For the cheaper home machines that have the pump that vibrates, adjusting the pressure is not possible without engaging in DIY hacks. However, companies such as Cafflano are developing technology that makes use of Pascal's Principle to maintain pressure within the portafilter during the brewing process.

Temperature

Temperature is among the most important elements in the perfect espresso shot. If the water is too hot, it will scorch the coffee grounds and produce an over-extracted bitter drink. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water extract all the desired coffee flavors without burning the grounds or excessively extracting.

The best espresso machines will include a thermoblock that will heat the water, and keeps it at a constant temperature throughout the entire extraction cycle. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system which constantly monitors the temperature of the water and adjusts if needed, ensuring that the brewhead remains at a perfect temperature for extraction.

Many coffee drinkers know that the temperature of your espresso maker is a key factor in the production of a good cup of coffee. The ideal brewing temperature for espresso is between 190 to 196 degrees Fahrenheit. To achieve this, your machine must have a quality thermoblock or thermocoil and the boiler must be sized to the correct size.

It is also crucial to heat your machine, portafilter, and cup prior to making a shot. Inability to heat your equipment is among the most common mistakes that can be made by novice espresso makers. This is the reason you should always read the instruction manual before making espresso for the first time.

Grind

A barista espresso machine should provide a variety grind settings to give you the most control over your final cup of coffee. Some machines include an analog gauge that looks cool and helps you develop your brewing capabilities. You should aim to maintain the pressure at nine bars throughout the process of brewing. This machine is getting close to hitting that target.

Another great feature of this machine is the built-in burr grinder. This is an excellent feature for newbies to espresso as it will not require you to shell out money for an additional burr grinder. The stainless steel conical grinder features 18 settings that range from "coarse to fine."

The grinder isn't as effective as a stand-alone device, but it's a good start and will have you on the path to brewing quality espresso shots. It's easy to clean and you can even pause it while grinding and avoid the creation of a mountain of grounds that spill across your portafilter as it makes its way to the tamping.

This beautiful and functional machine will allow you to feel like a barista from your own home. It's a great option for those who wish to to revisit the fond memories of pouring microfoam into their morning coffee and locking a portafilter in the grouphead, and tamping with precision. A bean to cup machine is a great option for those who are looking for convenience.

Water

Water can be a challenging thing to master. The trick is to find the appropriate balance. Too much can cause mineral deposits to develop in your machine. Too little could result in an espresso that is weaker.

The ideal espresso water is soft and high in alkalinity. It is recommended to use a filter that removes chlorine and adds a tiny amount (TDS) of total dissolved substances to add calcium and magnesium. This will ensure an ideal balance between acidity and hardness and also avoid the necessity of decalcifying.

A high-quality, coffeee filtered water is vital to your machine's overall health as well as the taste of the coffee it produces. Descaling products must be regularly used depending on the hardness and frequency of use of your machine. The products are available in liquid, powder and tab forms and are available at all hardware stores.
