What to Look For in a Barista Espresso Machine

The espresso machine is among the most complex coffee machines in the world. It is comprised of three primary components. The bottom contains the water and the middle is the filter-basket.

This machine was a huge hit and helped to popularize the prosumer (home barista) espresso market. Features include a 2.2L steam boiler, low pressure pre-infusion & 9 bar pressure for brewing.

Pressure

If you're an avid coffee drinker, you will know that the pressure of your machine is a major factor in the quality of your coffee and espresso maker. It doesn't matter if you're seeking a thick layer of crema, or the right balance of acidity and flavor, the pressure of your espresso machine is the key to brewing perfect espresso.

BARs (Barometric pressure) is the amount of force that your espresso machine exerts on the coffee machines espresso grounds while delivering high-pressure water. Your espresso machine is pushing heated water through the coffee grounds at a rate nine times the current atmospheric pressure.

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

The pressure of your espresso machine can be controlled by adjusting the screw on the espresso pump. Commercial machines and some high-end home machines use pumps with rotary that can be adjusted. For the cheaper home machines that use a vibrating motor, it is not possible to alter the pressure without hacks. Companies like Cafflano however, are working on technology which uses Pascal's Principle to ensure the pressure within the portafilter all through the beer making process.

Temperature

The temperature is one of the most critical factors for the perfect espresso shot. The water that is too hot can scorch the coffee grounds, resulting in bitter brew. The ideal temperature for extraction is 200 degrees Fahrenheit which allows the water to extract all of the coffee's desirable flavors without scorching the grounds, or over-extracting.

The best espresso machines include the thermoblock, also known as a thermocoil, which heats water and keeps it at a constant temperature throughout the extraction. The Breville Barista Express has a PID system (Proportional Integral Derived) that constantly monitors and adjusts the temperature. This ensures that the brewhead is at the ideal temperature for extraction.

Most coffee lovers are aware that the temperature of the espresso maker is crucial to brewing a perfect cup of coffee. The ideal brewing temperature for espresso is between 190 and 196 degrees Fahrenheit. To achieve this, you need a machine with a good thermoblock, thermocoil and boiler that is correctly sized.

It is also essential to heat your espresso maker, portafilter and cup before you make the shot. A failure to warm your espresso maker is one of the most frequent mistakes committed by novice espresso makers. This is why it is important to always go through the instruction manual prior to making Electric Espresso Maker for the first time.

Grind

A barista machine must give you a variety of grind settings so you have the maximum control over your final cup of espresso. Some machines come with an analog gauge which looks cool and aids you improve your brewing abilities. Ideally, you should get around nine bars of pressure, and keep that throughout the brewing cycle. Although this machine isn't hitting the mark, it's quite close and will serve you well.

Another wonderful feature of this machine is a built-in burr grinder. This feature is great for novices because it doesn't mean having to purchase an additional grinder. The stainless steel conical grinder comes with 18 settings, ranging from "coarse to fine."

The grinder isn't as good as a stand-alone unit, but it's a solid start and will put you on the path to brewing quality espresso shots. It's easy-to-clean and you can stop the grinder during the process of grinding to avoid accumulating an overwhelming amount of ground in your portafilter when it is being put through the tamper.

This beautiful and functional machine will allow you to enjoy the barista experience in your own home. This is an excellent option for anyone who would like to relive the thrill of pouring microfoam into their morning coffee and locking the portafilter into the head of the grouphead and tamping the coffee with precision. For those who want convenience, a bean to cup machine might be a better option.

Water

Water can be a tricky thing to master. Finding the right balance is vital. If you're using too much, it could result in mineral deposits on your machine, however too little and you'll struggle make a full cup of espresso.

The ideal espresso water is low in hardness and high in alkalinity. It is best 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 ensure an ideal balance between hardness and acidity and avoid the need to decalcify.

It is important to use water filtered of high quality for the health and flavor of your machine. Based on the usage and hardness of your machine you should make use of descaling products on a regular schedule. These products are available in liquid, powder or tab form at the majority of hardware stores.
