What to Look For in a Barista Espresso Machine

Pressure

If you are an avid coffee drinker, then you'll be aware that the pressure of your machine is a crucial element in the quality of your coffee. The pressure of your machine is essential to making excellent coffee, whether you're seeking a thick layer or the perfect balance of acidity and flavor.

BARs (Barometric pressure) is the force your espresso machine exerts on the grounds of the coffee while delivering high-pressure water. 9 BARs means that your espresso machine is forcing heated water through the ground coffee at a rate of nine times the Earth's current atmospheric pressure.

The pressure of your espresso machine is vital as it allows the water to pass through the grounds of your coffee with the right speed and intensity. If the pressure is too low the flavors and oils dissolved won't 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 changing the screw that is attached to the espresso pump. Commercial machines and some high-end home machines use the rotary pumps, which are adjustable. For the cheaper home machines that utilize the vibrating pump, altering the pressure isn't possible without getting into DIY hacks. Companies such as Cafflano, however, are working on technology that uses Pascal's Principle in order to maintain the pressure within the portafilter all through the beer making process.

Temperature

The temperature is one of the most crucial factors to the perfect espresso shot. Too hot water can burn the grounds of the coffee, leading to bitter drink. The optimal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all the desired coffee flavors without burning the grounds or over-extracting.

The top espresso machines come with the thermoblock, or thermocoil which heats the water and keeps it at a constant temperature throughout the extraction cycle. The Breville Barista Express, for instance, comes with a PID (Proportional Integral Derivative) system that continuously monitors the temperature of water and adjusts as necessary, ensuring that the brewhead remains at the ideal temperature for extraction.

Many coffee drinkers are aware that the temperature of an espresso machine is crucial to a good cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190 and 196 degrees. To achieve this, you need an espresso maker with a reliable thermoblock, thermocoil and a boiler that is properly sized.

This is the reason why you should always read the instruction manual before making espresso for the first time.

Grind

Some machines have an analog pressure gauge that looks cool and can help you gain knowledge about the brewing process. Ideally, you want to hit about nine bars of pressure and keep this throughout the entire brewing process. This machine is very close to the goal.

Another nice touch on this machine is that it has a built-in burr grinder. This feature is perfect for novices because it doesn't mean the need to purchase a separate grinder. The stainless steel conical grinder features 18 settings, which range from "coarse to fine."

This grinder isn't as good as a stand-alone unit, but it will get you started on the path to making great espresso shots. It's easy to clean, and you can even pause it during the grinding process, which helps you avoid the creation of a mountain of grounds that will spill across your portafilter as it makes its way to tamping.

The best home espresso machine espresso water has the lowest alkalinity and hardness level. It is recommended to use a water filter that removes chlorine and adds a tiny amount (TDS) of total dissolved substances to add calcium and magnesium. This will result in an optimal balance between alkalinity and hardness and prevent the necessity of decalcifying your equipment.

Using a high-quality filter water is vital for your machine's long-term health as well as the taste of the coffee it produces. Based on the type of use and hardness of your machine you should use a descaling product on a regular schedule. The products are available in liquid, powder and tab forms and are available at the majority of hardware stores.
