What to Look For in a Barista Espresso Machine
The espresso machine is among the most complicated coffee machines available. It is made up of three primary components. The bottom houses the water and the middle contains the filter-basket.
This machine was a huge success and helped popularize the prosumer (home barista) espresso market. It features a 2.2L steam boiler, a low pressure pre-infusion and 9 bar pressure for brewing.
Pressure
If you're serious about coffee, then you know the pressure of your espresso machine is an important aspect in how well your drinks turn out. The pressure of your machine is essential in brewing excellent coffee whether you're seeking a thick layer or a perfect balance of flavor and acidity.
BARs (Barometric pressure) is the force your espresso machine exerts on the grounds of coffee while pumping high-pressure water. 9 BARs means that your espresso machine is pushing heated water through the coffee grounds at a rate of nine times the current atmospheric pressure.
The pressure of your machine is essential because it allows the water to move through coffee grounds at a proper speed and intensity. If the pressure isn't high enough the flavors and oils will not be extracted correctly. On the other however, if the pressure is too high, the water will be forced through the coffee grounds too quickly and you'll end up 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 machines and some of the top-end home appliances have the rotary pumps, which are adjustable. For the more affordable home appliances that utilize an oscillating pump, changing the pressure isn't possible without getting into DIY hacks. Companies like Cafflano however, are working on technology which uses Pascal's Principle in order to maintain the pressure within the portafilter all through the fermentation process.
Temperature
The temperature is one of the most critical factors for a great espresso shot. The water that is too hot can scorch the grounds of the coffee, resulting in a bitter drink. 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 best espresso machines will feature a thermoblock, or thermocoil which is used to heat the water and keep it at a stable temperature throughout the entire extraction process. The Breville Barista Express has a PID system (Proportional Integral Derived) that continuously monitors and adjusts the temperature. This ensures that the brewhead remains at the correct temperature for extraction.
Many coffee enthusiasts know that the temperature of your espresso machine is an essential element in making a quality cup of coffee. The ideal temperature for espresso is between Fahrenheit 190 and 196. To attain this, you will require an espresso machine with a top thermoblock, thermocoil, and a boiler that is sized correctly.
In addition, it's important to pre-heat your portafilter, espresso machine, and cup prior to taking espresso. The failure to preheat is among the most common errors made by beginner espresso makers. Always read the espresso machine's instructions before you begin using it for the first time.
Grind
A barista machine must give you a variety of grind settings so that you can have the most control over your final cup of espresso. Some machines come with an analog gauge that looks cool and can help you to improve your brewing skills. Ideally, you want to hit about nine bars of pressure and keep this throughout the entire brewing process. This machine is near reaching that goal.
Another great feature of this machine is that it has a built-in burr grinder. This feature is perfect for beginners since it eliminates the need for a separate grinder. The grinder is a conical stainless steel device with 18 settings, ranging from "coarse" to "fine."
This grinder isn't as good as a stand-alone unit, but it can get you started on the right track to read more making great espresso shots. It's easy-to-clean and you can stop the grinder during the grinding process to prevent accumulating a large amount of ground on your portafilter as it's being crushed.
This is a beautiful and functional machine that will allow you to experience the joy of becoming a barista from home. This is a great option for those who wish to relive the thrill of pouring microfoam in their morning cup of coffee and locking the portafilter into the grouphead's head and tamping it with precision. If you're looking for convenience, a bean to cup machine could be the better choice.
Water
Water can be a challenging thing to master. Finding the right balance is crucial. Too much can cause mineral deposits to form in your machine. But too little can result in a weaker cup of espresso.
The perfect water for espresso is low in hardness and high in alkalinity. It is recommended to use a water purifier which does not use chlorine and adds a tiny amount (TDS) of total dissolved substances to add calcium and magnesium. This will result in an ideal balance of alkalinity as well as hardness. It will also help avoid the necessity to decalcify your equipment.
Using a high-quality filter water is essential to your machine's long term health and the flavor of the coffee it makes. Based on the usage and the hardness of your machine, you should use descaling products on a regular basis. These products come in powder, liquid and tab forms and are available at all hardware stores.
The Breville Barista Express is a premium, high-end home espresso machine designed to bring the cafe experience to your home. It comes with more advanced features when compared to other espresso machines that are beginner-friendly, and is targeted at those who are looking to refine their techniques and perfect their art of coffee. The thermocoil heater, with an integrated PID controller, placed on the group head which is actively heated which makes it simple to regulate your brewing temperatures. This is a huge advantage over other entry-level models, which require you to spend a lot of time "temperature-surfing" to ensure an even shot of espresso.
