What to Look For in a Barista Espresso Machine
The espresso machine is among the most complicated coffee machines available. It is comprised of three primary components. The bottom holds the water and the middle is a filtration basin with a metal filter.
The machine was a huge hit and helped popularize the home barista espresso. Features include a low pressure pre-infusion, a 2.2L boiler, and the brewing pressure of 9 bars.
Pressure
If you are a coffee lover, you'll know that the pressure of your machine is a major element in the quality of your coffee. If you're looking for a thick layer of crema or right balance of flavor and acidity, the pressure of your espresso maker is crucial to making good espresso.
BARs (Barometric Pressure) refer to the force applied to the coffee grounds when your espresso machine is pumping out its high-pressure water. 9 BARs means that the espresso machine is pushing heated water through the ground coffee at a 9 times the current atmospheric pressure.
The pressure of your machine is important because it allows water to pass 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 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.
The pressure of your espresso machine can be adjusted by turning the screw on the espresso pump. Commercial machines and high-end home machines have the rotary pumps that have adjustable pressure. For home-based machines that use a vibrating motor, it's impossible to adjust the pressure without hacks. However, companies such as Cafflano are developing technology that employs Pascal's Principle to maintain pressure in the portafilter during the fermentation process.
Temperature
Temperature is among the most important elements in the making of a good espresso shot. If the water is too hot, it may scorch the coffee grounds and create an over-extracted bitter espresso. The ideal temperature for extraction is 200 degrees Fahrenheit. This allows the water to extract all of the desired coffee flavors without burning the grounds or over-extracting.
The top espresso machines include a thermoblock or thermocoil that is used to heat the water and keep it at a stable temperature throughout the whole extraction process. The Breville Barista Express, for example, features a PID (Proportional Integral Derivative) system that continuously monitors the temperature of the water and adjusts if needed making sure that the brewhead stays at the ideal temperature to extract the coffee.
The majority of coffee drinkers are aware that the temperature of your espresso maker is a key factor in brewing a great cup of coffee. The ideal temperature for brewing espresso is between 190 and 196 degrees Fahrenheit. To get this temperature, you need a machine with a good thermoblock, thermocoil and boiler that is correctly sized.
It is also essential to pre-heat your espresso maker or portafilter coffee machines espresso before making espresso. Beginners often make the mistake of not preheating their machine. It is recommended to read your espresso machine's manual prior to attempting to try it for the very first time.
Grind
A barista espresso machine must provide a variety grind settings to give you the greatest control over the final cup of coffee. Some machines include an analog pressure gauge, which is cool and can help you gain knowledge about your brewing skills. The ideal goal is to hit about nine bars of pressure, and keep it throughout the brewing process. This machine is near reaching that goal.
A built-in burr mill is a great feature. This feature is ideal for beginners since it eliminates having to purchase a separate grinder. The grinder is a stainless steel conical device that has 18 settings from "coarse" to "fine."
It's not the same as a stand-alone device, but it's a solid start and will get you on your way to making quality espresso shots. It's easy to clean and you can stop it during the grinding process, which helps you avoid making a mountain of ground that can spill onto your portafilter on its way to making tamps.
This is a beautiful and practical machine that allows you to experience the thrill of being a barista home. It's an excellent choice for those who wish to to look back at the memories of pouring the microfoam into their morning cup of joe by locking a portafilter to the grouphead, and then tamping with precision. For those who want convenience, a bean-to- cup machine could be a better fit.
Water
It is a challenge to master. Finding the right balance is key. Too much and it can cause mineral deposits to build up in your machine, however too little and you'll struggle get a rich cup of espresso.
The perfect espresso water has the lowest alkalinity and hardness level. This is best achieved using a water filter system which eliminates chlorine and brings an amount of total dissolved solids (TDS) to add calcium and magnesium to the mix. This will create a balanced balance of hardness and alkalinity and will prevent the necessity of decalcifying your machine.
It is vital to use water that is filtered and of excellent quality for the health and flavor of your machine. Based on the type of use and the hardness of your machine, you should make use of descaling products regularly. These products are available as powder, liquid or tab form at most hardware stores.
The Breville Barista Express, a premium espresso machine for home use designed to bring the cafe experience into your home. It comes with more advanced features than other beginner machines which are targeted at coffee lovers who want to perfect their technique and perfect their craft. The thermocoil heater that has an integrated PID controller situated on the group head that is continuously heated allows you to control your brewing temperature. This is a major advantage over competing entry-level models that require you to spend longer "temperature surfing" in order to pull an espresso shot that is consistent.
