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 primary components. The bottom houses the water and the middle contains the filter-basket.
This machine was a huge hit and helped spread the prosumer (home barista) espresso market. Its features include a low pressure pre-infusion and a 2.2L boiler and the brewing pressure of 9 bars.
Pressure
If you're serious about your coffee, then you know the pressure of your espresso maker is an important aspect in how your drinks taste. 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 great espresso.
BARs (Barometric Pressure) refer to the amount of force applied to the coffee grounds when your espresso machine is delivering its high-pressure water. Your espresso machine is pushing heated water through the grounds of your coffee at nine times Earth's current atmosphere pressure.
The pressure of your espresso machine is vital because it allows water to move through the grounds of coffee at the proper speed and in the right amount. If the pressure is too low, the flavors and oils dissolved will not be extracted properly. On the other however, if the pressure is too high, the water will be pushed through the coffee grounds too fast and you'll end up with an over-extracted, weak cup of espresso.
The pressure of your espresso machine can be adjusted by turning the screw that is located on the espresso pump. Commercial machines and some high-end home machines use pumps with rotary that can be adjusted. For the cheaper home machines that use a vibrating motor, it's not possible to adjust the pressure with DIY hacks. Companies like Cafflano however, are working on technology which uses Pascal's Principle to ensure pressure in the portafilter during the brewing process.
Temperature
The temperature is among the most critical factors for an espresso shot that is perfect. If the water is too hot, it can ignite the coffee grounds and result in an over-extracted bitter drink. The ideal extraction temperature is around 200 degrees Fahrenheit, which allows the water to extract all the desired flavors of coffee without burning the grounds or over-extracting.
The top espresso machines come with a thermoblock, or thermocoil which heats the water and keeps it at a constant temperature throughout the extraction. The Breville Barista Express, for example, features PID (Proportional Integral Derivative) system that continuously monitors the water temperature and adjusts it as needed making sure that the brew head stays at a perfect temperature to extract the coffee.
The majority of coffee drinkers know that the temperature of the espresso machine is essential to making a great cup of coffee. The ideal temperature for espresso is between Fahrenheit 190 and 196. To get this temperature, you need an espresso machine that has a high-quality thermoblock, thermocoil or thermoblock and a boiler that is sized correctly.
It is also essential to espresso home machine pre-heat your espresso maker, portafilter and cup before making shots. Beginner espresso makers often make the mistake of not heating their machine prior to making a shot. This is why it is important to always read the instruction manual before making use of your espresso maker 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 include an analog gauge which looks cool and aids you to improve your brewing skills. Ideally, you should get around nine bars of pressure and maintain this throughout the entire brewing process. This machine is close to getting to that point.
Another great feature of this machine is the built-in burr grinder. This feature is great for beginners because it eliminates having to purchase an additional grinder. The grinder is a conical stainless steel device with 18 settings from "coarse" to "fine."
It's not as efficient as a stand-alone device, but it can get you started on the path to make great espresso shots. It's easy to clean and you can even pause it while grinding this will help you avoid creating a pile of grounds that will spill all over your portafilter on its way to the tamping.
This is a beautiful and functional machine that allows you to experience the joy of being a barista at home. It's a great choice for those who want to be able to look back on the moments of pouring microfoam into their morning coffee and locking a portafilter in the grouphead, and then tamping with precision. If you're looking for convenience, a bean to cup machine could be the better choice.
Water
Water can be a tricky thing to master. The trick is to find the proper balance. Too much can cause mineral deposits to develop in your machine. However, too little will result in an espresso cup that is weaker.
The best espresso water has a low hardness and alkalinity level. This is best accomplished by using an effective water filtering system that bypasses all chlorine and adds back in a small amount of total dissolved solids (TDS) to add some calcium and magnesium to the mix. This will create a balanced balance of hardness and alkalinity and will reduce the necessity of decalcifying your machine.
It is important to use water that is filtered and of high quality for the health and taste of your machine. Descaling products must be used on a regular basis according to the strength and use of your machine. These products are available in tab, liquid, or powder form at most hardware stores.
The Breville Barista Express, a premium espresso machine for home use, is designed to bring the cafe experience to your home. It comes with more advanced features than other machines for beginners that are designed for coffee enthusiasts who wish to improve their technique and improve their craft. The thermocoil heating system that comes with an integrated PID controller mounted on the actively heated group head makes it easy to control your brewing temperature. This is a big advantage over other models at the entry level which require long periods of "temperature-surfing" to ensure a consistent espresso shot.
