What to Look For in a Barista Espresso Machine
The espresso machine is among the most intricate coffee machines available. It is comprised of three main components. The bottom holds the water while the middle is a filter-basket with a filter made of metal.
This machine was a huge success and was instrumental in bringing home barista espresso. It features a 2.2L steam boiler, low pressure pre-infusion & 9 bar brewing pressure.
Pressure
If you're serious about coffee and know that the pressure of your espresso machine is an important factor in how well your drinks are made. Whether you're looking for a thick layer of crema or the perfect balance of flavor and acidity, the pressure of your espresso maker is essential to making perfect espresso.
BARs (Barometric pressure) is the force your espresso machine exerts on grounds of the coffee while delivering high-pressure water. 9 BARs mean that your espresso machine is forcing heated water through the ground coffee at 9 times the current atmospheric pressure.
The pressure of the espresso machine is crucial because it allows the water to flow through the coffee grounds at the right speed and in the right amount. If the pressure is low, the oils and flavors will not be extracted properly. If the pressure is too low, the flavors and oils dissolved will not be extracted properly.
The pressure of your espresso machine can be adjusted by turning the screw on the espresso pump. Commercial machines as well as some high-end home appliances have rotating pumps that can be adjusted. But for the more affordable home machines that use an oscillating pump, changing the pressure isn't possible without using DIY hacks. However, companies like Cafflano are developing technology that utilizes Pascal's Principle to create maintained pressure inside the portafilter during the making process.
Temperature
The temperature is one of the most important factors in brewing a great espresso shot. Too hot water can burn the grounds of the coffee, resulting in a bitter brew. The ideal temperature for extraction is about 200 degrees Fahrenheit, which allows the water to extract all the coffee's desirable flavors without scalding the grounds or over-extracting.
The best espresso machines will have a thermoblock or thermocoil which warms the water and keeps it at a steady temperature throughout the whole extraction process. The Breville Barista Express, for instance, comes with a PID (Proportional Integral Derivative) system which constantly monitors the temperature of the water and adjusts it as needed, ensuring that the brew head stays at the ideal temperature to extract the coffee.
Many coffee drinkers are aware that the temperature of an espresso machine is vital to brewing a great cup of coffee. The ideal temperature for brewing espresso is between 190 to 196 degrees Fahrenheit. To achieve this, you need an espresso maker with a reliable thermoblock, thermocoil here and boiler that is correctly sized.
It is also crucial to warm your portafilter, espresso machine, and cup before you make an espresso. Beginners who make espresso 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 using your espresso maker for the first time.
Grind
A barista machine must give you a variety of grind settings, so that you have the maximum control over your final cup of espresso. Some machines include an analog pressure gauge, that looks cool and can help you gain knowledge about your brewing techniques. Ideally, you should get around nine bars of pressure and keep it throughout the brewing process. Although this machine isn't hitting that target, it is quite close and will serve you well.
Another wonderful feature of this machine is its built-in burr grinder. This is a great feature for people who are new to espresso since it doesn't require them to shell out money for a separate burr grinder. The stainless steel conical grinder features 18 settings that range from "coarse to fine."
This grinder isn't quite the same as a stand-alone unit, but it's a solid start and will put you on your way to creating quality espresso shots. It's easy to clean, and you can pause it during the grinding process to avoid creating a pile of ground that will fall over your portafilter while on its way to tamping.
This gorgeous and useful machine lets you enjoy the barista experience in your home. It's an excellent choice for those who want to be able to look back on the fond memories of pouring microfoam into their morning cup of joe, locking a portafilter into the grouphead, and tamping with precision. A bean-to-cup machine is a good option for those who are looking for convenience.
Water
Water can be a tricky thing to master. The trick is finding the proper balance. Too much caffeine can cause mineral deposits to build up in your machine. However, too little will result in less of an espresso.
The best espresso water has a low hardness and alkalinity level. It is best to use a water purifier which does not use chlorine and adds a small amount (TDS) of total dissolved substances in order to add calcium and magnesium. This will result in an ideal balance of alkalinity and hardness, and will prevent the necessity of decalcifying your machine.
Using high-quality filtered water is vital to your machine's overall health as well as the taste of the coffee it makes. Depending on the use and hardness of your machine, you should use a descaling product on a regular schedule. These products are available in powder, liquid or tab form at a majority of hardware stores.
The Breville Barista Express is a premium, high-end home espresso machine that was designed to bring the cafe experience to your home. It has more advanced features over other basic machines which are targeted at coffee lovers who want to improve their technique and perfect their craft. The thermocoil heater, with an integrated PID controller, centered on the group head that is constantly heated, makes it easy to control your brewing temperature. This can be a huge advantage over the other models that require more time "temperature surfing" to get a consistent espresso.
