What to Look For in a Barista Espresso Machine

BARs (Barometric Pressure) refer to the amount of force exerted 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 grounds of the coffee at a rate nine times Earth's current atmosphere pressure.

The pressure of your machine is important because it allows water to pass through coffee grounds at a proper speed and intensity. If the pressure is too low the flavors and oils dissolved will not be extracted properly. On the other however, if the pressure is too high the water will be pushed through the coffee grounds too quickly, and you'll end up with a weak and over-extracted cup of espresso.

You can control the pressure of your espresso machines for home maker by adjusting the screw on the espresso pump. Commercial and high-end home machines have rotary pumps with adjustable pressure. For the more affordable home machines that utilize the vibrating pump, altering the pressure is difficult without using DIY hacks. Companies like Cafflano, however, are developing technology which uses Pascal's Principle to ensure pressure in the portafilter during the fermentation process.

Temperature

The temperature is among the most crucial factors to the perfect espresso shot. If the water is too hot, it can cause the coffee grounds to burn and create a bitter coffee. The optimal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all desired coffee flavors without burning the grounds or over-extracting.

The best espresso machine espresso machines feature a thermoblock, or thermocoil that will heat the water, and keeps it at a stable temperature throughout the entire extraction cycle.

Grind

A barista espresso machine should also have a variety of grind settings to give you the most control over your final cup of coffee. Some machines come with an analog pressure gauge, which is cool and can help you learn about your brewing techniques. Ideally, you should reach around nine bars of pressure and keep that throughout the brew cycle. While this machine does not hit the mark, it's quite close and will serve you well.

Another nice touch on this machine is its built-in burr grinder. This is a great feature for espresso newbies because it eliminates the need to purchase a separate burr grinder. The grinder is an stainless steel conical unit with 18 settings from "coarse" to "fine."

The ideal espresso water has an alkalinity and hardness that is low level. It is best cheap espresso machine to use a water purifier that removes chlorine and adds a small amount (TDS) of total dissolved substances in order to add calcium and magnesium. This will create an ideal balance of alkalinity and hardness and prevent the need to decalcify your machine.
