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 parts. The bottom contains the water and the middle the filter-basket.
This machine was a huge success and helped popularize the prosumer (home barista) espresso market. Features include a 2.2L steam boiler, a low pressure pre-infusion & 9 bar pressure for brewing.
Pressure
If you're a coffee enthusiast, you'll be aware that the pressure of your espresso machine is a crucial factor in the quality of your beverages. The pressure of your machine is essential in brewing excellent coffee whether you're seeking a thick layer or the perfect balance of flavor and acidity.
BARs (Barometric pressure) is the force your espresso machine applies to the grounds of coffee while pumping high-pressure water. 9 BARs means that the espresso machine is forcing heated water through the ground coffee at a the rate of nine times the current atmospheric pressure.
The pressure of your machine is important because it allows water to flow through coffee grounds at the correct speed and intensity. If the pressure is low the oils and flavors aren't extracted properly. On the other contrary, if 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 found on the espresso pump. Commercial machines and some of the top-end home appliances have rotary pumps that are adjustable. For home-based machines that utilize a vibration motor, it is impossible to adjust the pressure with DIY hacks. However, companies such as Cafflano are developing technology that uses Pascal's Principle to maintain pressure within the portafilter during the fermentation process.
Temperature
The temperature is among the most critical factors for an excellent espresso shot. Hot water can cause burning of the grounds of coffee, which can result in a bitter drink. The ideal temperature for extraction is 200 degrees Fahrenheit, which allows the water to extract all the desired coffee flavors without scorching the grounds or over-extracting.
The best espresso machines have a thermoblock or thermocoil that will heat the water, and keeps it at a constant temperature throughout the entire extraction process. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system that continuously monitors the temperature of water and adjusts according to the need making sure that the brew head stays at the right temperature to extract the coffee.
Many coffee drinkers are aware that the temperature of an espresso machine is vital to brewing a great cup of coffee. The ideal brewing temperature for espresso is between 190 and 196 degrees Fahrenheit. To attain this, your machine should have a high-quality thermoblock or thermocoil, and the boiler should be sized appropriately.
It is also important to preheat your espresso maker, portafilter and the cup prior to making an espresso. A failure to warm your espresso maker is one of the most common mistakes made by novice espresso makers. This is why it is important to always go through the instruction manual prior to using your espresso machine for the first time.
Grind
A barista machine must give you a range of grind settings so you can have the greatest control over your final cup of espresso. Some machines have an analog gauge which looks cool and aids you to improve your brewing skills. In the ideal scenario, you'll want to achieve around nine bars of pressure and maintain that throughout the brewing cycle. While this machine does not hit that target, it is pretty close and will be able to serve you well.
Another great feature of this machine is that it has a built-in burr grinder. This feature is ideal for those who are new to the field because it avoids having to buy an additional grinder. The grinder is an stainless steel conical unit that has 18 settings from "coarse" to "fine."
This grinder isn't quite the same as a stand-alone unit, however, it's a decent start and will have you on the path to making high-quality espresso shots. It's easy to clean, and you can pause it while grinding and avoid making a mountain of ground that can spill across your portafilter as it makes its way to the tamping.
This beautiful and functional machine will allow you to be a barista at your own home. It's a great option for those who want to be able read more to revisit the memories of pouring microfoam into their morning cup of joe by locking a portafilter to the grouphead, and then tamping with precision. For those who want convenience, a bean-to- cup machine could be a better option.
Water
Water is a difficult thing to master. The key is to find the appropriate balance. Too much caffeine can result in mineral deposits on your machine, however too little and you'll struggle to enjoy a satisfying cup of espresso.
The ideal espresso water is low in hardness and high in alkalinity. This can be achieved with an water filter system that removes chlorine and puts back a small amount of total dissolving solids (TDS) to add calcium and magnesium to the mix. This will result in an optimal balance between hardness and alkalinity and will prevent the necessity of decalcifying your machine.
Using a high quality filtered water is vital for your machine's long-term health as well as the taste of the coffee it produces. Descaling products should be used on a regular basis, depending on the hardness and use of your machine. The products are available in liquid, powder and tab forms and can be found at most hardware stores.
The Breville Barista Express is a premium, high-end home espresso machine that was designed to bring the experience of a cafe into your home. It has more advanced features over other basic machines which are targeted at those who are looking to perfect their technique and perfect their craft. The thermocoil heating system with integrated PID controller that is centered on the actively heated group head makes it simple to regulate the temperature of your coffee. This is an advantage over other basic models that require you to spend a lot of time "temperature-surfing" to achieve an even shot of espresso.
