What to Look For in a Barista Espresso Machine
The espresso machine is among the most complex coffee machines in the world. It is made up of three main parts. The bottom holds the water, and the middle is 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 as well as an 2.2L boiler and brewing pressure of 9 bar.
Pressure
If you're serious about your coffee then you're aware that the pressure of your espresso maker is an important factor in how well your drinks turn out. 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 crucial to making excellent espresso.
BARs (Barometric pressure) is the amount of force that your espresso machine exerts on grounds of coffee while pumping high-pressure water. 9 BARs means that the espresso machine is pushing heated water through the ground coffee at a 9 times the current atmospheric pressure.
The pressure of the espresso machine is crucial because it's what allows the water to pass through the grounds of the coffee at the right speed and intensity. If the pressure is too low the flavors and oils will not be extracted correctly. If the pressure is too low, the flavors and oils dissolved won't be extracted properly.
The pressure of your espresso machine can be controlled by adjusting the screw on the espresso pump. Commercial machines and a few high-end home machines use rotating pumps that can be adjusted. For the cheaper home machines that utilize a vibrating pump, adjusting the pressure is not possible without involving DIY hacks. Companies such as Cafflano however, are working on technology that uses Pascal's Principle to ensure pressure in the portafilter during the making process.
Temperature
Temperature is among the most crucial factors in the perfect espresso shot. If the water is too hot, it can ignite the coffee grounds and result in an over-extracted bitter espresso. The ideal extraction temperature is about 200 degrees Fahrenheit which allows the water to extract all of the desirable coffee flavors without scorching the grounds or over-extracting.
The best espresso machines will feature a thermoblock, or thermocoil that will heat the water, and keeps it at a steady temperature throughout the entire extraction cycle. The Breville Barista Express, for instance, comes with a PID (Proportional Integral Derivative) system that continuously monitors the water temperature and adjusts as necessary, ensuring that the brew head remains at the perfect temperature for extraction.
Most coffee lovers are aware that the temperature of the espresso maker 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 or thermoblock and a boiler that is sized correctly.
Additionally, it is important to pre-heat your machine, portafilter, and cup prior to making the shot. Failure to preheat is one of the most common mistakes that can be made by beginner espresso makers. It is advisable to read your espresso machine's manual prior to attempting to start using it for the first time.
Grind
A barista machine must give you a variety of grind settings so that you have the maximum control over the final cup of espresso. Some machines have an analog pressure gauge which looks cool and can help you gain knowledge about the brewing process. The ideal goal is to achieve around nine bars of pressure, and keep this throughout the entire brewing process. Although this machine can't reach the desired pressure, it's quite close and will 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 doesn't require them to pay for an additional burr grinder. The grinder is an stainless steel conical unit with 18 settings ranging from "coarse" to "fine."
This grinder isn't quite the same as a standalone unit, however, it's a decent start and will put you on the right track to making quality espresso shots. It's easy to clean and you can also pause it during the grinding process this will help you avoid creating a pile of ground that can spill across your portafilter as it makes its way to tamping.
This is a beautiful and functional machine that allows you to feel the excitement of being a barista home. It's a great choice for anyone who would like to to look back at the memories of pouring microfoam into their morning coffee by locking a portafilter to the grouphead, and tamping with precision. A bean-to-cup machine is a great option for those who are looking for convenience.
Water
Water can be a challenging thing to master. Finding the right balance is crucial. Too much and it can cause mineral deposits to form in your machine, while too little and you'll struggle to enjoy a satisfying cup of espresso.
The ideal espresso water is soft and high in alkalinity. It is best to use a water purifier which does not use chlorine and adds a tiny amount (TDS) of total dissolved substances that add calcium and magnesium. This will create a good balance of alkalinity and hardness, and will prevent the necessity to decalcify your equipment.
Using a high quality filtered water is crucial to your machine's longevity health and the taste 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 basis. They are available in powder, liquid or tab in a variety of 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 is equipped with more advanced features compared to other beginner machines, and is geared read more towards coffee lovers who want to refine their technique and master the craft. The thermocoil heating system with a built-in PID controller centered on the actively heated group head makes it simple to regulate your brewing temperature. This is an benefit over other models that are entry-level, which will require you to spend a lot of time "temperature-surfing" to achieve a consistent espresso shot.
