What to Look For in a Barista Espresso Machine
The espresso machine is one of the most complicated coffee machines in the world. It is comprised of three main components. The bottom holds the water while the middle part 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 brewing pressure of 9 bar.
Pressure
If you're serious about coffee and espresso, then you're aware that the pressure of your espresso machine is a crucial factor in how well your drinks taste. If you're looking for an even layer of crema or 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 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 the rate of nine times the current atmospheric pressure.
The pressure of the espresso machine is crucial as it allows the water to move through the grounds of your coffee with the right speed and in the right amount. If the pressure is too low the dissolved oils and flavors aren't 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 that is located on the espresso pump. Commercial and high-end home machines have pumps that rotate with adjustable pressure. For home machines that are less expensive that use a vibrating motor, it is impossible to adjust the pressure without hacks. Companies such as Cafflano however, are working on technology that uses Pascal's Principle in order to maintain pressure in the portafilter during the making process.
Temperature
The temperature is among the most crucial factors to an excellent espresso shot. If the water is too hot, it can ignite the coffee grounds and produce an over-extracted bitter drink. The ideal extraction temperature is around 200 degrees Fahrenheit which allows the water to extract all of the desirable coffee flavors without burning the grounds or over-extracting.
The best espresso machines will include a thermoblock that warms the water and keeps it at a constant temperature throughout the entire extraction process. The Breville Barista Express, for instance, is equipped with a PID (Proportional Integral Derivative) system which constantly monitors the temperature of water and adjusts it as needed so that the brewhead remains at a perfect temperature to extract the coffee.
Many coffee drinkers know that the temperature of your espresso maker is a crucial factor in making a quality cup of coffee. The ideal brewing temperature for espresso is between 190 to 196 degrees Fahrenheit. To achieve this, you need an espresso machine with a top thermoblock, thermocoil or thermoblock and a boiler that is properly sized.
It is also important to heat your machine as well as the portafilter and cup prior to making the espresso. Espresso makers who are beginners often make the mistake of not preheating their machine. This is the reason you should always read the instruction manual before making use of your espresso maker for the first time.
Grind
A barista machine should offer you a variety of grind settings so you have the best control over the final cup of espresso. Some machines come with an analog gauge which looks cool and aids you develop your brewing capabilities. The goal is to maintain an average pressure of nine bars throughout the brewing cycle. While this machine does not hit the mark, it's pretty close and will be able to serve you well.
Another excellent feature of this machine is its built-in burr grinder. This is a fantastic feature for people who are new to espresso since it eliminates the need 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 as powerful as a stand-alone device, however, it's a decent start and will get you on the right track to brewing 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 the tamping.
This beautiful and functional machine will allow you to feel like a barista from your home. It's an excellent choice for anyone who wants to to look back at the memories of pouring the microfoam into your morning cup of coffee or locking a portafilter into the grouphead, and tamping with precision. If you're looking for convenience, a bean to cup machine could be the better choice.
Water
Water is a tricky thing to master. The trick is finding the proper balance. If you're using too much, it could cause mineral deposits in the machine, but too little and you'll struggle to enjoy a satisfying cup of espresso.
The best espresso water has a low hardness and alkalinity level. It is recommended to use a filter that bypasses chlorine and adds a small amount (TDS) of total dissolved substances to provide calcium and magnesium. This will ensure an ideal balance between hardness and acidity and avoid the need to decalcify.
Using high-quality filtered water is crucial for your machine's long-term health and the flavor of the coffee it produces. Depending on the use and hardness of your machine you should use a descaling product on a regular schedule. These products are available in powder, liquid and tab forms and can be found at many hardware stores.
The Breville Barista Express, a luxury high-end espresso machines home home espresso machine designed to bring the cafe experience into your home. It has more advanced features than other machines for beginners which are targeted at coffee lovers who wish to improve their technique and improve their craft. The thermocoil heating system with an integrated PID controller mounted around the heated group head makes it easy to regulate your brewing temperature. This is an benefit over other models that are entry-level, which require long periods of "temperature-surfing" to get consistent espresso shots.
