What to Look For in a Barista Espresso Machine
The espresso machine is one of the most intricate coffee machines available. It has three main parts. The bottom contains the water and the middle the filter-basket.
This machine was a huge success and helped to popularize the prosumer (home barista) espresso market. It features a low pressure pre-infusion, the 2.2L boiler and the brewing pressure of 9 bars.
Pressure
If you are an avid coffee drinker, then you will know that the pressure of your espresso machine is a major element in the quality of your coffee. It doesn't matter if you're seeking a thick layer of crema, or the right balance of flavor and acidity, the pressure of your espresso machine is essential to making perfect espresso.
BARs (Barometric pressure) is the amount of force that your espresso machine exerts on the coffee grounds 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 current atmospheric pressure.
The pressure of your machine is crucial because it allows water to pass through coffee grounds at the proper speed and intensity. If the pressure is too low, the oils and flavors will not be extracted properly. On the other contrary, if pressure is too high, the water will be pushed through the coffee grounds too quickly and you'll end with a weak, diluted cup of espresso.
The pressure of your espresso machine can be controlled by adjusting the screw located on the espresso pump. Commercial machines and a few high-end home machines have pumps with rotary that can be adjusted. However, for the less expensive home machines that utilize a vibrating pump, adjusting the pressure isn't possible without using DIY hacks. Companies such as Cafflano, however, are developing technology that uses Pascal's Principle in order to maintain pressure in the portafilter during the fermentation process.
Temperature
Temperature is among the most crucial factors in the perfect espresso shot. If the water is too hot, it can scorch the coffee grounds and create a bitter coffee. The ideal extraction temperature is about 200 degrees Fahrenheit, which allows the water to extract all of the desired flavors of coffee without scorching the grounds or over-extracting.
The best espresso machines have a thermoblock or thermocoil which is used to heat the water and keep it at a steady temperature throughout the entire extraction cycle. The Breville Barista Express, for instance, is equipped with PID (Proportional Integral Derivative) system that constantly monitors the temperature of water and adjusts according to the need making sure that the brewhead remains at a perfect temperature for extraction.
The majority of coffee drinkers are aware that the temperature of your espresso machine is a key factor in making a quality cup of coffee. The ideal temperature for brewing espresso is between 190 and 196 degrees Fahrenheit. To achieve this, you require a machine with a good thermoblock, thermocoil and a boiler that is appropriately sized.
In addition, it's important to pre-heat your machine, portafilter, and the cup prior to making a shot. Espresso makers who are beginners often make the mistake of not heating their machine prior to making a shot. This is why you should always read the instruction manual before using your espresso machine for the first time.
Grind
A barista espresso machine must provide a variety grind settings for you to have the most 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 the pressure at nine bars throughout the brewing cycle. This machine is very close to the goal.
A built-in burr mill is a great feature. This feature is great for novices because it doesn't mean the need for a separate grinder. The stainless steel conical grinder comes with 18 settings, ranging from "coarse to fine."
The grinder isn't as effective as a stand-alone unit, but it can get you started on the path to making great espresso shots. It's easy to clean, and you can stop the grinder in the grinding process to prevent accumulating a large amount of ground on your portafilter as it's being put through the tamper.
This gorgeous and practical machine lets you feel like a barista from your home. This is an excellent choice for those who wish to relive the thrill of pouring microfoam in their morning cup of coffee, locking the portafilter into the grouphead's head and tamping the coffee with precision. For those who simply want cafe espresso machine convenience, a bean-to- cup machine might be a better fit.
Water
Water is a tricky thing to master. Finding the right balance is crucial. Too much caffeine can cause mineral deposits to form in your machine. However, too little will result in less of an espresso.
The perfect espresso water has the lowest alkalinity and hardness level. It is recommended to use a filter which does not use chlorine and adds a tiny amount (TDS) of total dissolved substances that add calcium and magnesium. This will create an optimal balance between hardness and alkalinity and will avoid the necessity of decalcifying your machine.
It is essential to use water that is filtered and of good quality to ensure the health and flavor of your machine. Based on the type of use and hardness of your machine, you should make use of a descaling product regularly. These products come in liquid, powder and tab forms and can be found at many hardware stores.
The Breville Barista Express is a high-end, premium home espresso machine designed to bring the cafe experience inside your home. It has more advanced features than other machines for beginners, and is designed for coffee lovers who want to refine their technique and master the craft. The thermocoil heating system that comes with integrated PID controller that is centered on the actively heated group head makes it simple to regulate your brewing temperature. This is a major advantage over other models at the entry level which require much time "temperature-surfing" to ensure an even espresso shot.
