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 major components. The bottom houses the water and the middle 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 with the 2.2L boiler and the brewing pressure of 9 bars.
Pressure
If you're a coffee enthusiast, you will know that the pressure of your machine is a key factor in the quality of your drinks. You may be looking for an even layer of crema, or the perfect balance of flavor and acidity, the pressure of your espresso machine is the most important factor in brewing excellent espresso.
BARs (Barometric pressure) is the amount of force that your espresso machine exerts on the grounds of your coffee while delivering high-pressure water. 9 BARs indicates that your espresso machine is forcing heated water through the ground coffee at a an amount of nine times the current atmospheric pressure.
The pressure of your machine is crucial because it allows the water to pass through coffee grounds at the proper speed and intensity. If the pressure isn't high enough, the oils and flavors 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 that is located on the espresso pump. Commercial machines as well as some high-end home machines use the rotary pumps, which are adjustable. For the cheaper home machines that use the pump that vibrates, adjusting the pressure is difficult without getting into DIY hacks. However, companies such as Cafflano are working on technology that utilizes Pascal's Principle to create maintained pressure within the portafilter during the brewing process.
Temperature
Temperature is among the most important elements in a perfect espresso shot. If the water is too hot, it could scorch the coffee grounds and create a bitter espresso. The ideal temperature for extraction is 200 degrees Fahrenheit which allows the water to extract all the desired flavors of coffee without burning the grounds or over-extracting.
The top espresso machines have a thermoblock or thermocoil which heats the water and keeps it at a stable temperature throughout the entire extraction process. The Breville Barista Express has a PID system (Proportional Integral Derived) that constantly monitors and adjusts the water temperature. This ensures that the espresso machines brewhead remains at the ideal temperature for extraction.
The majority of coffee drinkers are aware that the temperature of your espresso maker is an important factor in brewing a great cup of coffee. The ideal brewing temperature for espresso is between 190 and 196 degrees Fahrenheit. To achieve this, you need an espresso machine that has a high-quality thermoblock, thermocoil, and a boiler that is appropriately sized.
It is also important to preheat your portafilter, machine, and cup prior to making espresso. The failure to preheat is among the most frequent errors made by beginners to making espresso. Always read the espresso machine's instructions before you begin using it for the first time.
Grind
A barista espresso machine must provide a variety grind settings to give you the most control over the final cup of coffee. Some machines come with an analog pressure gauge, that is stylish and can help you learn about your brewing skills. It is recommended to maintain the pressure of nine bars throughout the brewing process. This machine is very close to hitting that target.
Another excellent feature of this machine is a built-in burr grinder. This feature is great for novices because it doesn't mean the need for a separate grinder. The grinder is a conical stainless steel device that has 18 settings from "coarse" to "fine."
This grinder isn't as powerful as a standalone but it will get you started on the path to make great espresso shots. It's easy to clean, and you can stop it during the grinding process to avoid creating a pile of grounds that spill across your portafilter as it makes its way to the tamping.
This beautiful and functional machine will let you feel like a barista from your own 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 by locking a portafilter to the grouphead, and tamping with precision. For those who just want convenience, a bean to cup machine might be a better option.
Water
Water can be a tricky thing to master. Finding the right balance is key. Too much caffeine can cause mineral deposits to build up in your machine. But too little can result in a weaker cup of espresso.
The perfect water for espresso is soft and high in alkalinity. This is best accomplished by using an water filter system that eliminates chlorine and brings an amount of total dissolving solids (TDS) to add some calcium and magnesium to the mix. This will result in an ideal balance of alkalinity and hardness and reduce the necessity of decalcifying your equipment.
Using a high-quality filter water is vital 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 make use of descaling products regularly. The products are available in tab, liquid or powder form at most hardware stores.
The Breville Barista Express, a luxury high-end home espresso machine is designed to bring the cafe experience into your home. It is equipped with more advanced features than other machines for beginners and is designed for coffee enthusiasts who want refine their techniques and perfect their craft. The thermocoil heating system with an integrated PID controller, situated on the group head which is continuously heated and allows you to regulate your brewing temperatures. This is a major benefit over other models that are entry-level which require you to spend long periods of "temperature-surfing" to achieve consistent espresso shots.
