What to Look For in a Barista Espresso Machine
The espresso machine is among the most intricate coffee machines available. It is comprised of three major components. The bottom holds the water, and the middle is a basin for filtration with a metal filter.
This machine was a huge success and helped to popularize the prosumer (home barista) espresso market. It features a 2.2L steam boiler, low pressure pre-infusion, and 9 bar brewing pressure.
Pressure
If you are a coffee enthusiast, you'll be aware that the pressure of your espresso machine is a key factor in the quality of your drink. Whether you're looking for a thick layer of crema or perfect balance of flavor and acidity, the pressure of your espresso maker is essential to making great espresso.
BARs (Barometric pressure) is the force your espresso machine exerts upon the grounds of coffee while pumping high-pressure water. 9 BARs means that your espresso machine is pushing heated water through the ground coffee at a 9 times the current atmospheric pressure.
The pressure of your machine is vital because it allows the water to pass through the coffee grounds at the correct speed and intensity. If the pressure is too low, the oils and flavors aren't extracted properly. On the other hand, if the pressure is too high, the water will be forced through the coffee grounds too quickly and you'll end up with a weak, over-extracted cup of espresso.
The pressure of your espresso machine can be controlled by adjusting the screw on the espresso pump. Commercial machines and high-end home machines feature pumps that rotate with adjustable pressure. For the more affordable home appliances that utilize a vibrating pump, adjusting the pressure isn't possible without getting into DIY hacks. However, companies such as Cafflano are developing technology that utilizes Pascal's Principle to create maintained pressure inside the portafilter during the fermentation process.
Temperature
Temperature is one of the most crucial factors in a perfect espresso shot. If the water is too hot, it can scorch the coffee grounds and create a bitter espresso. The optimal temperature for extraction is 200 degrees Fahrenheit. This allows the water 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 water and keeps it at an unchanging temperature throughout the extraction cycle. The Breville Barista Express has a PID system (Proportional Integral Derived) which continuously monitors and adjusts the temperature of water. This makes sure that the brewhead stays at the correct temperature for extraction.
Most coffee lovers know that the temperature of an espresso machine is vital to brewing a great cup of coffee. The ideal temperature for espresso is between between 190 and 196 degrees. In order to get this temperature, your machine should have a high-quality thermoblock or thermocoil and the boiler must be sized appropriately.
It is also essential to heat up your machine or portafilter before making espresso. The failure to preheat is one of the most common mistakes that can be committed by novice espresso makers. It is recommended to read your espresso machine's manual before you start using it for the first time.
Grind
A barista machine ought to give you a variety of grind settings so that you can have the most control over your final cup of espresso. Some machines have an analog pressure gauge which is cool and can help you gain knowledge about the brewing process. You should strive to maintain the pressure of nine bars throughout the brewing process. Although this machine isn't hitting the mark, it's close enough and will serve you well.
Another nice touch on this machine is a built-in burr grinder. This is a great feature for people who are new to espresso since it eliminates the need to purchase an additional burr grinder. The grinder is a conical stainless steel device with 18 settings from "coarse" to "fine."
This grinder isn't quite as effective as a standalone unit, but it's a good beginning and will get you on the path to making quality espresso shots. It's easy to clean and you can pause the grinder during the process of grinding to avoid accumulating a huge amount of grounds on your portafilter while it's being stamped.
This is a beautiful and practical machine that will allow you to experience the excitement of being a barista at home. It's an excellent choice for those who wish to to revisit the moments of pouring microfoam into their morning cup of joe and locking a portafilter in the grouphead, and then tamping with precision. For those who simply want convenience, a bean-to- cup machine could be a better fit.
Water
It is a challenge to master. Finding the right balance is crucial. Too much and it can cause mineral deposits in the machine, but too little and you'll struggle enjoy a satisfying cup of espresso.
The ideal water for espresso is low in hardness and high in alkalinity. It is recommended to use a filter that removes chlorine and adds a tiny amount espresso coffee machines (TDS) of total dissolved substances that add calcium and magnesium. This will create an optimal balance between alkalinity and hardness and help avoid the need to decalcify your machine.
Using a high quality filtered water is essential for your machine's long-term health as well as the taste of the coffee it makes. Based on the type of use and hardness of your machine, you should use a descaling product on a regular schedule. They are available in powder, liquid or tab form at most hardware stores.
The Breville Barista Express is a premium, high-end home espresso machine that was designed to bring the cafe experience to your home. It offers more advanced features than other beginner machines that are designed for coffee lovers who wish to refine their techniques and perfect their craft. The thermocoil heating mechanism with integrated PID controller, centered on the active heated group head makes it easy to regulate the temperature of your coffee. This is a big advantage over other entry-level models, which require lots of time "temperature-surfing" to get an even espresso shot.
