What to Look For in a Barista Espresso Machine
The espresso machine is one of the most complicated coffee machines around the world. It is made up of three major components. The bottom holds the water, and the middle is a filter-basket with a filter made of metal.
This machine was a huge hit and helped popularize the prosumer (home barista) espresso market. It features a low pressure pre-infusion, an 2.2L boiler and the brewing pressure of 9 bars.
Pressure
If you're serious about your coffee then you're aware that the pressure of your espresso machine is an important aspect in how well your drinks turn out. If you're looking for a thick 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) refer to the force that is applied to the grounds of your coffee when your espresso machine is pumping out its high-pressure water. 9 BARs indicates that your espresso machine is pushing heated water through the ground coffee at a a rate of nine times the current atmospheric pressure.
The pressure of your machine is vital because it allows the water to move through coffee grounds at the right speed and intensity. If the pressure is too low, the oils and flavors will not be extracted properly. On the other hand, if the pressure is too high the water will be pushed through the coffee grounds too quickly, and you'll end up with a weak, over-extracted cup of espresso.
You can control the pressure of your espresso maker by changing the screw that is attached to the espresso pump. Commercial machines and some high-end home appliances have the rotary pumps, which are adjustable. For the cheaper home machines, which use a vibrating motor, it is not possible to alter the pressure without hacks. However, companies like Cafflano are working on technology that uses Pascal's Principle to maintain pressure within the portafilter during the beer making process.
Temperature
The temperature is among the most important aspects for an espresso shot that is perfect. The water that is too hot can scorch the grounds of coffee, which can result in a bitter espresso. The ideal extraction temperature is about 200 degrees Fahrenheit which allows the water to extract all of the coffee's desirable flavors without burning the grounds or over-extracting.
The best espresso machines feature a thermoblock, or thermocoil which will heat the water, and keeps it at a steady 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 the water and adjusts as necessary, ensuring that the brewhead stays at the perfect temperature for extraction.
Most coffee lovers know that the temperature of the espresso machine is essential to making a great cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190 and 196 degrees. In order to achieve this, your machine must have a quality thermoblock or thermocoil and the boiler needs to be sized appropriately.
It is also crucial to pre-heat your espresso maker or portafilter before making the espresso. A failure to warm your espresso maker is one of the most frequent errors made by beginner espresso makers. Always read the espresso machine's manual prior to attempting to use it for the first time.
Grind
A barista espresso machine must provide a variety grind settings for you to have the most control over your final cup of coffee. Some machines have an analog pressure gauge, that looks cool and can help you gain knowledge about your brewing skills. You should aim to maintain the pressure at nine bars throughout the brewing process. While this machine doesn't hit that target, it is pretty close and will serve you well.
A built-in burr mill is also a great feature. This is an excellent feature for newbies to espresso as it eliminates the need to buy a separate burr grinder. The grinder is a conical stainless steel unit with 18 settings ranging from "coarse" to "fine."
This grinder isn't as good as a standalone unit, but it will 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 avoid creating a mountainous amount of grounds on your portafilter as it's being tamped.
This gorgeous and useful machine will allow you to enjoy the barista experience in your own home. It's an excellent choice for those who wish to be able to revisit the memories of pouring the microfoam into your morning cup of coffee and locking a portafilter in the grouphead, and tamping with precision. For those who just want convenience, a bean to cup machine might be a better choice.
Water
Water is a challenging thing to master. The key is to find the optimal balance. Too much caffeine can cause mineral deposits to form in your machine. However, too little will result in less of an espresso.
The ideal water for espresso has the lowest alkalinity and hardness level. It is best to use a water filter that removes chlorine and adds a tiny amount (TDS) of total dissolved substances to add calcium and magnesium. This will create an optimal balance between espresso coffee machines alkalinity and hardness, and will reduce the need to decalcify your machine.
Using a high quality filtered water is crucial to your machine's longevity health as well as the taste of the coffee it makes. Descaling products should be utilized on a regular basis depending on the hardness and use of your machine. They are available in liquid, powder and tab forms and are available in most hardware stores.
The Breville Barista Express, a premium espresso machine for home use designed to bring the café experience into your home. It is more sophisticated than other machines for beginners that are designed for coffee lovers who want to perfect their technique and improve their craft. The thermocoil heater that has an integrated PID controller, placed on the group head which is heated continuously, makes it easy to regulate your brewing temperatures. This is an enormous advantage over competing entry-level models which require longer "temperature surfing" to ensure a consistent shot of espresso.
