What to Look For in a Barista Espresso Machine
The espresso machine is among the most complex coffee machines available. It is comprised of three major parts. The bottom is where the water goes and the middle contains the filter-basket.
This machine was a major hit and helped popularize the home barista espresso. It features a low pressure pre-infusion and a 2.2L boiler, and brewing pressure of 9 bar.
Pressure
If you're serious about coffee and espresso, then you're aware that the pressure of your espresso maker is an important aspect in how your drinks are made. The pressure of your machine is crucial to making excellent coffee, whether you're looking for a dense layer or a perfect balance of acidity and flavor.
BARs (Barometric pressure) is the force your espresso machine applies to the grounds of your coffee while delivering high-pressure water. 9 BARs means that the espresso machine is pushing heated water through the coffee grounds at 9 times the Earth's current atmospheric pressure.
The pressure of the espresso machine is crucial as it allows the water to flow through the grounds of the coffee at the right speed and with the right intensity. If the pressure is too low the flavors and oils dissolved won't be extracted properly. If the pressure is too low the dissolved oils and flavors won't be extracted properly.
You can control the pressure of your espresso maker by changing the screw that is attached to the espresso pump. Commercial machines and some of the top-end home appliances use rotating pumps that can be adjusted. For home machines that are less expensive that utilize a vibration motor, it is impossible to adjust the pressure without hacks. Companies such as Cafflano, however, are working on technology that is based on Pascal's Principle to ensure the pressure inside the portafilter throughout the brewing process.
Temperature
The temperature is one of the most important aspects for the perfect espresso shot. If the water is too hot, it can cause the coffee grounds to burn and produce an over-extracted bitter drink. The optimal temperature for extraction is 200 degrees Fahrenheit. This allows the water extract all the desired coffee flavors without burning the grounds or excessively extracting.
The best espresso machines have a thermoblock, or thermocoil that heats water and maintains it at an unchanging temperature throughout the extraction process. The Breville Barista Express, for instance, comes with a PID (Proportional Integral Derivative) system that constantly monitors the temperature of the water and adjusts if needed making sure that the brew head remains at the perfect temperature to extract the coffee.
Most coffee lovers know that the temperature of the espresso machine is crucial to brewing a perfect cup of coffee. The ideal brewing temperature for espresso is between 190 and 196 degrees Fahrenheit. To get this temperature, your machine must have a quality thermoblock or thermocoil and the boiler needs to be sized to the correct size.
Additionally, it is crucial to warm your portafilter, espresso machine, and the cup prior to making espresso. Inability to heat your equipment is one of the most common errors committed by novice espresso makers. This is the reason why you should always read the instruction manual before making use of your espresso maker for the first time.
Grind
A barista espresso machine should also offer a variety of grind settings for you to have the most control over the final cup of coffee. Some machines come with an analog pressure gauge which is cool and can help you learn about your brewing abilities. In the ideal scenario, you'll want to hit about nine bars of pressure and maintain that throughout the brewing cycle. While this machine doesn't hit this 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 those who are new to the field because it avoids the need to purchase a separate grinder. The stainless professional espresso machine steel conical grinder comes with 18 settings that range from "coarse to fine."
The grinder isn't as effective 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 stop the grinder in the process of grinding to prevent accumulating a large amount of grounds in your portafilter when it's being tamped.
It's a beautiful and practical machine that allows you to feel the excitement of being a barista at home. This is a great choice for those who want to relive the thrill of pouring microfoam in their morning cup of coffee, locking the portafilter into the head of the grouphead and tamping it with precision. A bean-to-cup machine is a great option for those who are looking for convenience.
Water
Water is a difficult thing to master. The trick is finding the optimal balance. If you're using too much, it could cause mineral deposits to form in your machine, while too small and you'll struggle to enjoy a satisfying cup of espresso.
The best espresso water has the lowest alkalinity and hardness level. It is recommended to use a water filter that does not contain chlorine and adds a tiny amount (TDS) of total dissolved substances to provide calcium and magnesium. This will result in an optimal balance between alkalinity and hardness, and will help avoid the necessity of decalcifying your equipment.
A high-quality, filtered water is vital to your machine's long term health and the taste of the coffee it produces. Descaling products must be utilized on a regular basis based on the hardness and use of your machine. These products are available in liquid, powder and tab forms and can be found in most hardware stores.
The Breville Barista Express, a top-of-the-line home espresso machine designed to bring the café experience into your home. It has more advanced features in comparison to other beginner machines, and is targeted at coffee enthusiasts who want refine their techniques and perfect their craft. The thermocoil heater that has an integrated PID controller, located on the group head that is constantly heated allows you to control your brewing temperature. This is a major advantage over other models at the entry level which will require you to spend lots of time "temperature-surfing" to get an even espresso shot.
