What to Look For in a Barista Espresso Machine
The espresso machine is one of the most intricate coffee machines around the globe. It is comprised of three major components. The bottom houses the water and the middle the filter-basket.
The machine was a huge success and helped to popularize home barista espresso. It features a 2.2L steam boiler, low pressure pre-infusion & 9 bar brewing pressure.
Pressure
If you are an avid coffee drinker, you'll realize that the pressure of your espresso machine is a key element in the quality of your drinks. The pressure of your machine is essential to making excellent coffee, whether you want a thick layer or a perfect balance of acidity and flavor.
BARs (Barometric Pressure) refer to the amount of force applied to the grounds of your coffee when your
electric espresso maker machine is delivering its high-pressure water. 9 BARs mean that your espresso machine is pushing heated water through the ground coffee at an amount of nine times the Earth's current atmospheric pressure.
The pressure of your machine is crucial because it allows the water to flow through coffee grounds at a proper speed and intensity. If the pressure is too low, the dissolved oils and flavors will not be extracted properly. If the pressure is too low, the flavors and oils dissolved will not be extracted correctly.
The pressure of your espresso machine can be adjusted by turning the screw on the espresso pump. Commercial
machines espresso and some of the top-end home machines use pumps with rotary that can be adjusted. For the cheaper home appliances that utilize an oscillating pump, changing the pressure isn't possible without getting into DIY hacks. Companies like Cafflano however, are working on technology that uses Pascal's Principle to ensure pressure within the portafilter throughout the making process.
Temperature
The temperature is one of the most critical factors for an espresso shot that is perfect. If the water is too hot, it could scorch the coffee grounds and result in an over-extracted bitter drink. The ideal extraction temperature is 200 degrees Fahrenheit, which allows the water to extract all the coffee's desirable flavors without scorching the grounds, or over-extracting.
The best espresso machines feature the thermoblock, or thermocoil which heats the water and keeps it at a constant temperature throughout the extraction. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system that constantly monitors the water temperature and adjusts according to the need making sure that the brew head stays at a perfect temperature for extraction.
Many coffee drinkers are aware that the temperature of the espresso machine 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 an espresso machine with a top thermoblock, thermocoil and boiler that is properly sized.
It is also crucial to heat your machine, portafilter, and cup prior to making the espresso. A failure to warm your espresso maker is one of the most common mistakes made by novice espresso makers. This is why you should always review the instruction manual before using your espresso maker for the first time.
Grind
A barista espresso machine should also have a variety of grind settings to give you the greatest control over your final cup of coffee. Some machines have an analog gauge which looks cool and aids you develop your brewing capabilities. You should strive to maintain a pressure of nine bars throughout the process of brewing. Although this machine isn't hitting the desired pressure, it's close enough and will serve you well.
A built-in burr mill is a nice touch. This is a wonderful feature for newbies to espresso as it doesn't require them to purchase a separate burr grinder. The grinder is a stainless steel conical device that has 18 settings from "coarse" to "fine."
This grinder isn't as powerful as a standalone, however, it's a decent start and will get you on your way to creating quality espresso shots. It's easy to clean, and you can also pause it while grinding to avoid the creation of a mountain of grounds that will spill onto your portafilter on its way to grinding.
This beautiful and functional machine will allow you to feel like a barista from your own home. This is an excellent choice for those who wish to recall the thrill of pouring microfoam into their morning cup of coffee while locking the portafilter in the grouphead's head and then tamping with precision. A bean to cup machine is a great choice to those who prefer convenience.
Water
Water is a difficult thing to master. The trick is to find the right balance. Too much can cause mineral deposits to build up in your machine, but too little and you'll struggle to get a rich cup of espresso.
The best espresso water has a low hardness and alkalinity level. It is recommended to use a water purifier that does not contain chlorine and adds a small amount (TDS) of total dissolved substances that add calcium and magnesium. This will create an ideal balance of hardness and alkalinity and will reduce the necessity to decalcify your equipment.
It is important to use water filtered of excellent quality for the health and flavor of your machine. Descaling products should be regularly used, depending on the hardness and use of your machine. The products are available in powder, liquid and tab forms and can be found at the majority of hardware stores.
