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 comprised of three major parts. The bottom contains the water and the middle is the filter-basket.
This machine was a huge hit and helped popularize the home barista espresso. Its features include a low-pressure pre-infusion as well as the 2.2L boiler, and brewing pressure of 9 bar.
Pressure
If you're serious about coffee, then you know the pressure of your espresso machine is a crucial factor in how well your drinks come out. It doesn't matter if you're seeking a thick layer of crema or perfect balance of acidity and flavor, the pressure of your espresso machine is the most important factor in brewing great espresso.
BARs (Barometric Pressure) refer to the amount of force exerted on the grounds of your coffee 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 machine is essential because it allows the water to pass through the coffee grounds at a proper speed and intensity. If the pressure isn't high enough the oils and flavors won't be extracted properly. If the pressure is too low, the dissolved oils and flavors will not be extracted correctly.
The pressure of your espresso machine can be controlled by adjusting the screw located on the espresso pump. Commercial machines and a few high-end home machines have rotating pumps that can be adjusted. For home machines that are less expensive that use a vibrating motor, it's impossible to adjust the pressure with DIY hacks. Companies such as Cafflano, however, are developing technology which uses Pascal's Principle to ensure pressure in the portafilter during the fermentation process.
Temperature
Temperature is one of the most important aspects in a great espresso shot. If the water is too hot, it can cause the coffee grounds to burn and create a bitter espresso. The ideal temperature for extraction is 200 degrees Fahrenheit which allows the water to extract all the coffee's desirable flavors without scorching the grounds or over-extracting.
The best espresso machines will include a thermoblock or thermocoil that warms the water and keeps it at a constant temperature throughout the whole extraction cycle. The Breville Barista Express has a PID system (Proportional Integral Derived) that constantly monitors and adjusts the temperature of water. This ensures that the brewhead is at the right temperature for extraction.
Many coffee enthusiasts know that the temperature of your espresso maker is a key factor in making a quality cup of coffee. The ideal temperature for espresso is between Fahrenheit 190 and 196. To attain this, your machine must have a quality thermoblock or thermocoil and the boiler must be of the right size.
It is also important to pre-heat your espresso maker, portafilter and cup before making espresso. Espresso makers who are beginners often make the mistake of not heating their machine prior to making a shot. It is recommended to read your espresso machine's instructions before you start using it for the first time.
Grind
A barista machine should give you a range of grind settings so you have the best control over your final cup of espresso. Some machines include an analog pressure gauge that is stylish and can help you learn about your brewing skills. The goal is to maintain an average pressure of nine bars throughout the brewing process. Although this machine can't reach that target, it is close enough and will serve you well.
A built-in burr mill is a nice touch. This is a fantastic feature for newbies to espresso as it will not require you to pay for an additional burr grinder. The stainless steel conical grinder features 18 settings, which range from "coarse to fine."
The grinder isn't as effective as a standalone unit, but it can help you get to the right path to creating great espresso shots. It's easy to clean, and you can stop the grinder during the process of grinding to prevent accumulating a large amount of grounds on your portafilter as it's being stamped.
This stunning and practical machine lets you feel like a barista from your own home. It's a great choice for anyone who would like to to look back on the memories of pouring microfoam into their morning coffee by locking a portafilter to the grouphead, and tamping with precision. For those who want convenience, a bean-to- cup machine could be a better option.
Water
Water is a challenging thing to master. The trick is finding the proper balance. Too much caffeine can cause mineral deposits to form in your machine. Too little could result in an espresso that is weaker.
The perfect water for espresso is low in hardness and high in alkalinity. This can be achieved with a water filter system that eliminates chlorine and brings back in a small amount of total dissolving solids (TDS) to add here some calcium and magnesium to the mix. This will give you a good balance between acidity and hardness, and prevent the need to decalcify.
It is crucial to make sure you use water that has been filtered to a good quality to ensure the health and flavor of your machine. Based on the type of use and the hardness of the machine, you should use a descaling product on a regular schedule. These products are available as powder, liquid or tab in a variety of hardware stores.
The Breville Barista Express, a premium espresso machine for home use, is designed to bring the café experience to your home. It comes with more advanced features compared to other beginner machines, and is targeted at coffee lovers who want to refine their technique and perfect their craft. The thermocoil heating system with an integrated PID controller, located on the group head which is actively heated, makes it easy to control your brewing temperature. This is an advantage over other entry-level models that require long periods of "temperature-surfing" to achieve an even shot of espresso.
