What to Look For in a Barista Espresso Machine

The espresso machine is among the most complicated coffee machines around the world. It is made up of three main parts. The bottom holds the water and the middle is a basin for filtration with a metal filter.

This machine was a huge success and helped spread the prosumer (home barista) espresso market. It features a low pressure pre-infusion, a 2.2L boiler and the brewing pressure of 9 bars.

Pressure

If you're an avid coffee drinker, you'll be aware that the pressure of your machine is a key element in the quality of your coffee. The pressure of your machine is vital for making great coffee espresso machines, whether you're seeking a thick layer or a perfect balance of acidity and flavor.

BARs (Barometric pressure) is the amount of force that your espresso machine applies to the coffee grounds while delivering high-pressure water. 9 BARs mean that your espresso machine is pushing heated water through the ground coffee at 9 times the current atmospheric pressure.

The pressure of your machine is essential because it allows water to pass through coffee machines espresso grounds at a proper speed and intensity. If the pressure isn't high enough, the oils and flavors will not be extracted correctly. On the other side, if the pressure is too high the water will be pushed through the coffee grounds too fast and you'll end up with a weak and over-extracted cup of espresso.

The pressure of your espresso machine can be controlled by adjusting the screw that is located on the espresso pump. Commercial machines and high-end home machines have the rotary pumps that have adjustable pressure. For the cheaper home machines that have a vibrating motor, it's impossible to adjust the pressure with DIY hacks. Companies like Cafflano however, are working on technology which uses Pascal's Principle in order to maintain the pressure inside the portafilter throughout the brewing process.

Temperature

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

The best espresso machines have the thermoblock, also known as a thermocoil that heats water and keeps it at a constant temperature throughout the extraction. The Breville Barista Express, for example, features PID (Proportional Integral Derivative) system which constantly monitors the water temperature and adjusts according to the need making sure that the brewhead stays at the right temperature for extraction.

Most coffee lovers know that the temperature of your espresso maker is a key factor in brewing a great cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190 and 196 degrees. To attain this, your machine should have a high-quality thermoblock or thermocoil and the boiler needs to be properly sized.

It is also important to preheat your machine, portafilter, and cup prior to making a shot. Beginner espresso makers often make the mistake of not heating their machine prior to making a shot. This is why it is important to always read the instruction manual before making espresso coffee machine with milk frother for the first time.

Grind

A barista espresso machine should also offer a variety of grind settings for you to have the most control over the final cup of coffee. Some machines include an analog pressure gauge, that is stylish and can help you gain knowledge about your brewing abilities. The goal is to maintain an average pressure of nine bars throughout the brewing cycle. While this machine does not hit this mark, it's pretty close and will be able to serve you well.

A built-in burr mill is a good feature. This feature is great for beginners because it eliminates having to purchase a separate grinder. The stainless steel conical grinder features 18 settings, which range from "coarse to fine."

It's not as efficient as a stand-alone device, but it will get you started on the right track to creating great espresso shots. It's easy to clean and you can put the grinder on hold during the grinding process to avoid accumulating a huge amount of grounds on your portafilter as it's being tamped.

It's a beautiful and practical machine that lets you to experience the joy of being a barista at home. It's a great choice for those who wish to to look back on the moments of pouring microfoam into your morning cup of coffee espresso machine by locking a portafilter to the grouphead, and then tamping with precision.

Water

Water can be a difficult thing to master. The key is to find the appropriate balance. Too much can cause mineral deposits to form inside your machine. However, too little will result in an espresso cup that is weaker.

The ideal espresso water is soft and high in alkalinity. This is best accomplished by using an water filter system that removes chlorine and puts back in a small amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will result in a balanced balance of alkalinity as well as hardness. It will also avoid the necessity of decalcifying your equipment.

Using a high quality filtered water is crucial for your machine's long-term health as well as the flavor of the coffee it makes. Based on the type of use and the hardness of your machine, you should make use of descaling products on a regular basis. These products are available in tab, liquid or powder form at most hardware stores.
