What to Look For in a Barista Espresso Machine
The espresso machine is among the most complicated coffee machines around the world. It is comprised of three main parts. The bottom houses the water, and the middle is the filter-basket.
This machine was a huge hit and was instrumental in establishing the prosumer (home barista) espresso market. It features a low pressure pre-infusion with the 2.2L boiler, and the brewing pressure of 9 bars.
Pressure
If you're an avid coffee drinker, then you'll be aware that the pressure of your espresso machine is a key factor in the quality of your beverages. Whether you're looking for an even layer of crema or right balance of acidity and flavor the pressure of your espresso machine is the key to brewing good espresso.
BARs (Barometric Pressure) refer to the force that is applied to the coffee grounds when your espresso machine is pumping out its high-pressure water. 9 BARs means that your espresso machine is pushing heated water through the ground coffee at a 9 times the current atmospheric pressure.
The pressure of your machine is vital because it allows water to pass through the coffee grounds at the right speed and intensity. If the pressure is too low the dissolved oils and flavors won't be extracted properly. On the other contrary, if pressure is too high, the water will be pushed through the coffee grounds too quickly and you'll end up with a weak and over-extracted cup of espresso.
The pressure of your espresso machine can be adjusted by turning the screw located on the espresso pump. Commercial machines and some high-end home appliances use the rotary pumps, which are adjustable. For the less expensive home machines that utilize a vibration motor, it's not possible to alter the pressure with DIY hacks. Companies like Cafflano, however, are working on technology that is based on Pascal's Principle in order to maintain pressure within the portafilter throughout the making process.
Temperature
Temperature is among the most important aspects in the perfect espresso shot. The water that is too hot can scorch the grounds of the coffee, leading to a bitter brew. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water extract all the desired coffee flavors without burning the grounds or over-extracting.
The best espresso machines will include a thermoblock or thermocoil which will heat the water, and keeps it at a steady temperature throughout the whole extraction cycle. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system that continuously checks the temperature of the water and adjusts if needed making sure that the brewhead stays at the perfect temperature for extraction.
Most coffee lovers know that the temperature of your espresso machine is an essential element in the production of a good cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190 and 196. To achieve this, you need a machine with a good thermoblock, thermocoil or thermoblock and a boiler that is sized correctly.
Additionally, it is essential to heat your espresso maker, portafilter and the cup prior to making an espresso. Failure to preheat is one of the most common mistakes committed by novice espresso makers. This is why you should always read the instruction manual before using your espresso machine for the first time.
Grind
A barista espresso machine must also have a variety of grind settings to give you the best control over your final cup of coffee. Some machines come with an analog gauge which looks cool and aids you improve your brewing skills. You should aim retro espresso machine to maintain a pressure of nine bars throughout the brewing cycle. While this machine does not hit the mark, it's close enough and will serve you well.
A built-in burr mill is another great feature. This is an excellent feature for people who are new to espresso since it doesn't require them to buy an additional burr grinder. The grinder is an stainless steel conical unit that has 18 settings from "coarse" to "fine."
This grinder isn't as powerful as a stand-alone device, but it can get you going in the right direction to making great espresso shots. It's easy to clean, and you can pause the grinder during the process of grinding to avoid creating a mountainous amount of grounds on your portafilter as it is being tamped.
It's a beautiful and functional machine that will allow you to experience 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 coffee, locking the portafilter into the grouphead's head and tamping with accuracy. For those who just want convenience, a bean-to- cup machine might be a better fit.
Water
Water can be a tricky thing to master. Finding the right balance is crucial. If you're using too much, it could cause mineral deposits to build up in the machine, but too little and you'll struggle to get a rich cup of espresso.
The best espresso water has low alkalinity and hardness level. This is best accomplished by using an effective water filtering system that bypasses all chlorine and adds an amount of total dissolved solids (TDS) to add some calcium and magnesium to the mix. This will help you achieve a good balance between acidity and hardness, and prevent the necessity of decalcifying.
Using a high-quality filter water is crucial to your machine's overall health and the flavor of the coffee it makes. A descaling product should be regularly used according to the hardness and usage of your machine. The products are available in powder, liquid and tab forms and can be found at the majority of hardware stores.
