What to Look For in a Barista Espresso Machine
The espresso machine is one of the most intricate coffee machines in the world. It is comprised of three main components. The base holds the water and the middle is a filter-basket with a metal filter.
This machine was a huge hit and helped to popularize the prosumer (home barista) espresso market. It features a low pressure pre-infusion with a 2.2L boiler and the brewing pressure of 9 bars.
Pressure
If you're serious about coffee, then you know the pressure of your espresso maker is a crucial factor in how your drinks taste. The pressure of your machine is essential for making great coffee, whether you want a thick layer or the perfect balance of acidity and flavor.
BARs (Barometric pressure) is the amount of force that your espresso machine applies to the grounds of your coffee while delivering high-pressure water. 9 BARs indicates that your espresso machine is forcing heated water through the coffee grounds at an amount of nine times the Earth's current atmospheric pressure.
The pressure of your machine is essential because it allows the water to flow through coffee grounds at the correct speed and intensity. If the pressure is too low, the flavors and oils dissolved aren't extracted properly. If the pressure is too low, the flavors and oils that are dissolved will not be extracted correctly.
The pressure of your espresso machine can be controlled by adjusting the screw found on the espresso pump. Commercial machines and top-end home machines have pumps that rotate with adjustable pressure. But for the more affordable home machines that utilize a vibrating pump, adjusting the pressure is impossible without involving DIY hacks. Companies such as Cafflano however, are developing technology that uses Pascal's Principle in order to maintain pressure within the portafilter throughout the beer making process.
Temperature
The temperature is one of the most important factors in brewing an espresso shot that is perfect. If the water is too hot, it may ignite the coffee grounds and result in an over-extracted bitter drink. The ideal temperature for extraction is 200 degrees Fahrenheit, which allows the water to extract all of the desirable coffee flavors without burning the grounds or over-extracting.
The top espresso machines include a thermoblock which is used to heat the water and keep it at a constant temperature throughout the whole extraction cycle. The Breville Barista Express, for instance, is equipped with PID (Proportional Integral Derivative) system which constantly checks the temperature of the water and adjusts it as needed making sure that the brew head remains at here the right temperature to extract the coffee.
Many coffee drinkers are aware that the temperature of an espresso machine is crucial to a good cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190-196. To get this temperature, you need an espresso maker with a reliable thermoblock, thermocoil or thermoblock and a boiler that is sized correctly.
It is also essential to heat up your machine, portafilter, and cup prior to making shots. Beginners who make espresso often make the mistake of not preheating their machine. This is the reason you should always read the instruction manual before making espresso for the first time.
Grind
A barista espresso machine should 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 to improve your brewing skills. The goal is to maintain the pressure of nine bars throughout the entire brewing process. Although this machine isn't hitting 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 is a great feature for newbies to espresso as it will not require you to purchase an additional burr grinder. The stainless steel conical grinder features 18 settings, which range from "coarse to fine."
This grinder isn't the same as a standalone unit, but it's a good start and will put you on your way to making quality espresso shots. It's easy to clean and you can stop it during the grinding process and avoid creating a mountain of ground that will fall across your portafilter as it makes its way to grinding.
This gorgeous and useful machine will allow you to experience being a barista in your own home. It's a great option for those who wish to to look back at the memories of pouring the microfoam into your morning cup of coffee and locking a portafilter in the grouphead, and tamping with precision. If you're looking for convenience, a bean to cup machine could be the better choice.
Water
Water can be a challenging thing to master. The trick is finding the optimal balance. Too much can cause mineral deposits to develop in your machine. But too little will result in an espresso that is weaker.
The ideal espresso water is low in hardness and high in alkalinity. This is best achieved using a water filter system which does away with chlorine and then adds back a small amount of total dissolved solids (TDS) to add some calcium and magnesium to the mix. This will result in a balanced balance of alkalinity and hardness, and will help avoid the need to decalcify your machine.
A high-quality, filtered water is essential to your machine's overall health and the flavor of the coffee it makes. Based on the type of use and the hardness of your machine, you should make use of a descaling product on a regular schedule. These products come in liquid, powder and tab forms and are available at all hardware stores.
The Breville Barista Express, a premium espresso machine for home use, is designed to bring the café experience to your home. It is equipped with more advanced features in comparison to other espresso machines that are beginner-friendly, and is designed for those who are looking to refine their technique and perfect the craft. The thermocoil heating system with an integrated PID controller centered on the group head that is constantly heated which makes it simple to control your brewing temperature. This is an enormous benefit over other models that require you to spend more time "temperature surfing" in order to pull a consistent espresso.
