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 components. The base holds the water and the middle is a basin for filtration with a filter made of metal.
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, the 2.2L boiler, and brewing pressure of 9 bar.
Pressure
If you're a coffee enthusiast, you will know that the pressure of your espresso machine is a major factor in the quality of your coffee. It doesn't matter if you're seeking a thick layer of crema or right balance of flavor and acidity, the pressure of your espresso maker is essential to making great espresso.
BARs (Barometric Pressure) refer to the force exerted on the coffee grounds when your espresso machine is delivering its high-pressure water. The espresso machine is pushing hot water through the grounds of the coffee at a rate nine times the current atmospheric pressure.
The pressure of your espresso machine is important because it's what allows the water to flow through the grounds of your coffee with the right speed and with the right intensity. If the pressure is too low, the flavors and oils dissolved won't be properly extracted. If the pressure is too low the flavors and oils dissolved won't be extracted properly.
You can control the pressure of your espresso maker by adjusting the screw of the espresso maker. Commercial machines and some high-end home machines use rotary pumps that are adjustable. For home machines that are less expensive that utilize a vibration motor, it's not possible to adjust the pressure without hacks. Companies such as Cafflano however, are working on technology which uses Pascal's Principle to ensure the pressure inside the portafilter throughout the fermentation process.
Temperature
The temperature is among the most critical factors for the perfect espresso shot. Too hot water can burn the grounds of coffee, which can result in a bitter espresso. The ideal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all the desired coffee flavors without burning the grounds or over-extracting.
The top espresso machines come with a thermoblock, or thermocoil which heats the water and keeps it at an even temperature throughout the extraction process. The Breville Barista Express, for instance, is equipped with PID (Proportional Integral Derivative) system that constantly monitors the temperature of the water and adjusts if needed making sure that the brewhead stays at the perfect temperature for extraction.
Most coffee lovers know that the temperature of your espresso maker is a crucial factor in brewing a great cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190 and 196. In order to achieve this, your espresso machine must be equipped with a reliable thermoblock or thermocoil, and the boiler should be properly sized.
It is also essential to heat up your machine, portafilter and cup before making espresso. The failure to preheat is among the most frequent errors made by novice espresso makers. This is why you should always go through the instruction manual prior to using your espresso machine for the first time.
Grind
A barista machine ought to give you a range of grind settings to ensure that you have the maximum control over the final cup of espresso. Some machines have an analog pressure gauge that looks cool and can help you learn about your brewing abilities. The ideal goal is to get around nine bars of pressure, and keep it throughout the brewing process. While this machine doesn't hit the mark, it's pretty close and will be able to serve you well.
A built-in burr mill is another good feature. This feature is ideal for beginners since it eliminates the need for an additional grinder. The grinder is a conical stainless steel device that has 18 settings from "coarse" to "fine."
It's not as efficient as a standalone unit, but it can get you going in the right direction to making excellent espresso shots. It's easy-to-clean and you can put the grinder on hold during the grinding process to prevent accumulating a large amount of grounds on your portafilter as it's being put through the tamper.
This is a beautiful and functional machine that allows you to feel the excitement of being a barista at home. This is an excellent choice for anyone who would like to recall the thrill of pouring microfoam into their morning coffee, locking the portafilter into the head of the grouphead and tamping the coffee with precision. A bean to cup machine is a great option for those looking for a simple and convenient solution.
Water
Water can be a challenging thing to master. It's important to find the appropriate balance. If you're using too much, it could result in mineral deposits on your machine, while too little and you'll struggle enjoy a satisfying cup of espresso.
The ideal water for espresso is soft and high in alkalinity. This is best achieved using an water filter system that eliminates chlorine and brings an amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will create a good balance of alkalinity and hardness and avoid the necessity of decalcifying your equipment.
Using a high quality filtered water is essential for your machine's long-term health as well as the flavor of the coffee it produces. Based on the type of use and hardness of your machine, you should make use of descaling products regularly. These products come in liquid, machines espresso machines powder and tab forms and can be found in the majority of hardware stores.
The Breville Barista Express is a premium, high-end home espresso machine designed to bring the experience of a cafe into the home. It has more advanced features over other basic machines that are designed for coffee lovers who wish to refine their techniques and improve their craft. The thermocoil heating system with a built-in PID controller centered around the heated group head makes it easy to regulate your brewing temperature. This is a major advantage over other models at the entry level that require you to spend lots of time "temperature-surfing" to ensure an even espresso shot.
