What to Look For in a Barista Espresso Machine
The espresso machine is among the most complex coffee machines in the world. It is composed of three main parts. The bottom is where the water goes and the middle the filter-basket.
This machine was a huge success and was instrumental in establishing the prosumer (home barista) espresso market. Its features include a low-pressure pre-infusion, an 2.2L boiler, and brewing pressure of 9 bar.
Pressure
If you're a coffee lover, you'll realize that the pressure of your espresso machine is an important factor in the quality of your drink. If you're looking for an even layer of crema or perfect balance of flavor and acidity, the pressure of your espresso machine is essential to making good espresso.
BARs (Barometric pressure) is the force your espresso machine exerts on grounds of the coffee while delivering high-pressure water. 9 BARs means that the espresso machine is pushing heated water through the coffee grounds at the rate of nine times the Earth's current atmospheric pressure.
The pressure of your machine is crucial because it allows the water to pass through coffee grounds at the correct speed and intensity. If the pressure isn't sufficient the oils and flavors will not be extracted properly. If the pressure is too low, the dissolved oils and flavors will not be extracted correctly.
You can control the pressure of your espresso maker by changing the screw of the espresso maker. Commercial machines and some of the top-end home appliances use rotary pumps that are adjustable. For the cheaper home appliances that utilize the pump that vibrates, adjusting the pressure is impossible without using DIY hacks. Companies such as Cafflano however, are developing technology that utilizes Pascal's Principle to ensure the pressure within the portafilter all through the beer making process.
Temperature
Temperature is among the most important factors in a perfect espresso shot. The water that is too hot can scorch the grounds of the coffee, resulting in bitter drink. The optimal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all the desired coffee flavors without scorching the grounds or over-extracting.
The best espresso machines include a thermoblock, or thermocoil that heats water and keeps it at an unchanging temperature throughout the extraction. The Breville Barista Express, for instance, is equipped with a PID (Proportional Integral Derivative) system that constantly checks the temperature of the water and adjusts it as needed, ensuring that the brew head stays at the ideal temperature for extraction.
Many coffee drinkers are aware that the temperature of the espresso maker is crucial to a good cup of coffee. The ideal brewing temperature for espresso is between 190 to 196 degrees Fahrenheit. To achieve this, your machine must have a quality thermoblock or thermocoil and the boiler must be sized to the correct size.
In addition, it's important to pre-heat your machine, portafilter, and cup before you make a shot. The failure to preheat is one of the most common errors made by beginners to making espresso. You should always read your espresso machine's manual before you try it for the very first time.
Grind
A barista espresso machine should also have a variety of grind settings for you to have the most control over your final cup of coffee. Some machines include an analog pressure gauge which is cool and can help you gain knowledge about your brewing abilities. It is recommended to maintain the pressure at nine bars throughout the entire brewing process. This machine is getting close to the goal.
A built-in grinder is another nice touch. This feature is perfect for beginners because it eliminates the need to purchase an additional grinder. The grinder is a conical stainless steel unit with 18 settings from "coarse" to "fine."
This grinder isn't as good as a standalone unit, but it can get you going in the right direction to making great espresso shots. It's easy to clean and you can stop the grinder during the grinding process to avoid accumulating a huge amount of grounds in your portafilter when it is being tamped.
This is a beautiful and functional machine that will allow you to experience the thrill of being a barista at home. It's a great choice for those who want to to look back on the memories of pouring microfoam into their morning cup of joe, locking a portafilter into the grouphead, and then tamping with precision. A bean-to-cup machine is a good option for those who are looking for convenience.
Water
Water can be a challenging thing to master. Finding the right balance is key. Too much can cause mineral deposits to form in your machine. But too little can result in less of an espresso.
The perfect water for espresso is low in hardness and high in alkalinity. This is best accomplished by using a water filter system which home espresso machine bypasses all chlorine and adds an amount of total dissolving solids (TDS) to add calcium and magnesium to the mix. This will create an ideal balance of alkalinity and hardness and reduce the need to decalcify your machine.
A high-quality, filtered water is crucial for your machine's long-term health and the flavor of the coffee it makes. Descaling products should be used on a regular basis, depending on the hardness and usage of your machine. These products come in liquid, powder and tab forms and can be found at the majority of hardware stores.
The Breville Barista Express, a premium espresso machine for home use, is designed to bring the café experience into your home. It comes with more advanced features compared to other machines for beginners and is geared towards coffee enthusiasts who want refine their techniques and perfect their art of coffee. The thermocoil heating system with an integrated PID controller mounted on the actively heated group head makes it simple to regulate the temperature of your coffee. This is a huge benefit over other models that are entry-level which need you to spend much time "temperature-surfing" to ensure consistent espresso shots.
