What to Look For in a Barista Espresso Machine
The espresso machine is among the most complicated coffee machines around the world. It consists of three main components. The bottom holds the water while the middle is a basin for filtration with a filter made of metal.
This machine was a huge hit and was instrumental in establishing the prosumer (home barista) espresso market. Its features include a low pressure pre-infusion with the 2.2L boiler, and the brewing pressure of 9 bars.
Pressure
If you're serious about coffee then you're aware that the pressure of your espresso maker is an important factor in how well your drinks turn out. Whether you're looking for a thick layer of crema, or the right balance of flavor and acidity, the pressure of your espresso maker is essential to making good espresso.
BARs (Barometric Pressure) refer to the amount of force that is imposed on the coffee grounds when your espresso machine is delivering its high-pressure water. 9 BARs means that the espresso machine is forcing heated water through the ground coffee at a an amount of nine times the Earth's current atmospheric pressure.
The pressure of the espresso machine is crucial because it allows the water to flow through the grounds of coffee at the proper speed and with the right intensity. If the pressure is low the oils and flavors won't be extracted properly. On the other side, if the pressure is too high, the water will be forced through the coffee grounds too fast and you'll end with a weak, over-extracted cup of espresso.
You can regulate the pressure of your espresso maker by adjusting the screw on the espresso pump. Commercial machines and some high-end home appliances have rotary pumps that are adjustable. For the cheaper home machines that have the vibrating pump, altering the pressure is not possible without getting into DIY hacks. Companies such as Cafflano however, are working on technology that utilizes Pascal's Principle to ensure the pressure within the portafilter all through the brewing process.
Temperature
The temperature is one of the most critical factors for the perfect espresso shot. Too hot water can burn the grounds of coffee, which can result in bitter espresso. 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 feature a thermoblock, or thermocoil that is used to heat the water and keep it at a steady temperature throughout the entire extraction cycle. The Breville Barista Express, for instance, comes with a PID (Proportional Integral Derivative) system that constantly checks the temperature of the water and adjusts if needed so that the brewhead remains at a perfect temperature for extraction.
Most coffee lovers are aware that the temperature of the espresso maker is vital to brewing a great cup of coffee. The ideal brewing temperature for espresso is between 190 and 196 degrees Fahrenheit. To achieve this, you require an espresso maker with a reliable thermoblock, thermocoil and a boiler that is sized correctly.
It is also crucial to heat up your machine, portafilter and cup before making a shot. Beginner espresso makers often make the mistake of not preheating their machines. This is the reason you should always read the instruction manual before making espresso coffee machine for home for the first time.
Grind
A barista espresso machine must also provide a variety grind settings to give you the best 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 techniques. You should aim to maintain a pressure of nine bars throughout the brewing process. While this machine doesn't hit the mark, it's pretty close and will be able to serve you well.
A built-in burr mill is another excellent feature. This is a fantastic feature for those who are new to espresso because it eliminates the need to pay for an additional burr grinder. The stainless steel conical grinder comes with 18 settings that range from "coarse to fine."
It's not as good as a standalone, however, it's a decent start and will get you well on your way to making quality espresso shots. It's easy to clean and you'll be able to stop the grinder in the process of grinding to avoid creating a mountainous amount of ground on your portafilter as it's being stamped.
This is a beautiful and functional machine that will allow you to experience the excitement of becoming a barista from home. It's an excellent choice for those who wish to be able to look back on the memories of pouring the microfoam into their morning coffee, locking a portafilter into the grouphead, and tamping with precision. For those who simply want convenience, a bean-to- cup machine could be a better fit.
Water
Water can be a tricky thing to master. Finding the right balance is vital. Too much caffeine can result in mineral deposits on your machine, while too little and you'll struggle get a good cup of espresso.
The ideal espresso water is soft and high in alkalinity. It is best to use a water purifier that does not contain chlorine and adds a small amount (TDS) of total dissolved substances that add calcium and magnesium. This will result in an optimal balance between alkalinity as well as hardness. It will also avoid the necessity of decalcifying your equipment.
It is crucial to use water that is filtered and of excellent quality for the health and flavor of your machine. Depending on the use and hardness of your machine you should use descaling products regularly. They are available in powder, liquid and tab forms and are available at most hardware stores.
The Breville Barista Express is a top-of-the-line, luxurious home espresso machine that was designed to bring the cafe experience into your home. It comes with more advanced features when compared to other machines for beginners, and is designed for coffee enthusiasts who want refine their technique and perfect their art of coffee. The thermocoil heating system that comes with integrated PID controller that is centered on the active heated group head makes it easy to regulate the temperature of your coffee. This is a significant advantage over other entry-level models which require longer "temperature surfing" to get a consistent espresso.
