What to Look For in a Barista Espresso Machine
The espresso machine is one of the most intricate coffee machines around the globe. It is made up of three main parts. The bottom houses the water and the middle is the filter-basket.
This machine was a huge success and helped spread the prosumer (home barista) espresso market. Features include a 2.2L steam boiler, a low pressure pre-infusion and 9 bar brewing pressure.
Pressure
If you're an avid coffee drinker, you will know that the pressure of your espresso machine is a major factor in the quality of your coffee. You may be looking for an even layer of crema or the perfect balance of acidity and flavor The pressure of your espresso maker is the most important factor in brewing perfect espresso.
BARs (Barometric pressure) is the amount of force that your espresso machine exerts upon the grounds of coffee while pumping high-pressure water. The espresso machine is pushing heated water through the grounds of coffee at nine times Earth's current atmosphere pressure.
The pressure of your espresso machine is vital as it allows the water to move through the coffee grounds at the right speed and with the right intensity. If the pressure is too low, the flavors and oils dissolved aren't extracted properly. On the other contrary, if pressure is too high, the water will be forced through the coffee grounds too fast and you'll end with a weak and over-extracted cup of espresso.
You can control the pressure of your espresso maker by adjusting the screw of the espresso maker. Commercial machines as well as some high-end home machines use rotating pumps that can be adjusted. For home-based machines that use a vibrating motor, it is impossible to adjust the pressure without DIY hacks. Companies like Cafflano, however, are working on technology that utilizes Pascal's Principle to ensure pressure within the portafilter throughout the making process.
Temperature
Temperature is one of the most important aspects in a great espresso shot. The water that is too hot can scorch the grounds of coffee, which can result in a bitter drink. The ideal extraction temperature is 200 degrees Fahrenheit, which allows the water to extract all of the coffee's desirable flavors without scorching the grounds or over-extracting.
The best espresso machines will include a thermoblock which is used to heat the water and keep it at a constant temperature throughout the whole extraction cycle. The Breville Barista Express, for example, features PID (Proportional Integral Derivative) system that continuously monitors the temperature of the water and adjusts if needed so that the brew head stays at the perfect temperature for extraction.
Most coffee lovers know that the temperature of an espresso machine is crucial to a good cup of coffee. The ideal brewing temperature for espresso is between 190 to 196 degrees Fahrenheit. To get this temperature, you need an espresso machine with a top espresso coffee machine thermoblock, thermocoil or thermoblock and a boiler that is correctly sized.
In addition, it is crucial to warm your portafilter, machine, and the cup prior to making espresso. Beginner espresso makers often make the mistake of not heating their machine prior to making a shot. It is recommended to read your espresso machine's instruction manual before you begin using it for the first time.
Grind
A barista espresso machine must also provide a variety grind settings to give you the best control over the final cup of coffee. Some machines come with an analog gauge that is cool and helps you improve your brewing skills. Ideally, you should reach around nine bars of pressure and maintain that throughout the brewing cycle. Although this machine isn't hitting the mark, it's close enough and will serve you well.
Another great feature of this machine is its built-in burr grinder. This feature is perfect for beginners since it eliminates the need to purchase an additional grinder. The grinder is a conical stainless steel device that has 18 settings from "coarse" to "fine."
This grinder isn't quite as effective as a standalone, but it's a solid beginning and will get you on the right track to brewing quality espresso shots. It's easy to clean and you'll be able to stop the grinder in the grinding process to avoid accumulating an overwhelming amount of ground in your portafilter when it is being put through the tamper.
This gorgeous and practical machine will let you experience being a barista in your home. It's a great choice for those who want to to revisit the fond memories of pouring microfoam into their morning cup of joe or locking a portafilter into the grouphead, and tamping with precision. For those who just want convenience, a bean to cup machine might be a better choice.
Water
Water can be a tricky thing to master. Finding the right balance is essential. If you're using too much, it could cause mineral deposits in the machine, but too small and you'll struggle to make a full cup of espresso.
The best espresso water has the lowest alkalinity and hardness level. This is best achieved using a water filter system that bypasses all chlorine and adds back in a small amount of total dissolving solids (TDS) to add calcium and magnesium to the mix. This will ensure the right balance between hardness and acidity and also avoid the necessity of decalcifying.
Using high-quality filtered water is vital for your machine's long-term health and the taste of the coffee it makes. Descaling products should be utilized on a regular basis, depending on the hardness and frequency of use of your machine. The products are available in liquid, powder or tab form at most 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 than other beginner machines designed for coffee lovers who want to improve their technique and perfect their craft. The thermocoil heating system with an integrated PID controller, situated on the group head which is continuously heated allows you to control your brewing temperature. This is a big advantage over other entry-level models which will require you to spend long periods of "temperature-surfing" to ensure an even shot of espresso.
