What to Look For in a Barista Espresso Machine
The espresso machine is one of the most complicated coffee machines on the planet. It is comprised of three primary components. The bottom holds the water, and the middle is a filter-basket with a filter made of metal.
This machine was a huge success and was instrumental in establishing the prosumer (home barista) espresso market. Features include a low pressure pre-infusion as well as the 2.2L boiler, and brewing pressure of 9 bar.
Pressure
If you're an avid coffee drinker, then you'll know that the pressure of your machine is an important element in the quality of your beverages. It doesn't matter if you're seeking an even layer of crema, or the perfect balance of acidity and flavor, the pressure of your espresso machine is the most important factor in brewing perfect espresso.
BARs (Barometric Pressure) refer to the force exerted 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's what allows the water to pass through the grounds of the coffee at the right speed and with the right intensity. If the pressure is low the oils and flavors won't be extracted properly. If the pressure is too low, the flavors and oils dissolved will not be extracted correctly.
You can control the pressure of your espresso maker by changing the screw that is attached to the espresso pump. Commercial machines and some high-end home appliances have rotary pumps that are adjustable. However, for the less expensive home machines that have the vibrating pump, altering the pressure isn't possible without getting into DIY hacks. Companies like Cafflano however, are developing technology that is based on Pascal's Principle to ensure the pressure inside the portafilter throughout the beer making process.
Temperature
Temperature is among the most important elements in the perfect espresso shot. Hot water can cause burning of the grounds of the coffee, resulting in bitter brew. The ideal temperature for extraction is 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 have a thermoblock or thermocoil which warms the water and keeps it at a constant temperature throughout the entire extraction process. The Breville Barista Express, for example, features a PID (Proportional Integral Derivative) system which constantly monitors the temperature of water and adjusts it as needed so that the brewhead stays at the perfect temperature for extraction.
Many coffee enthusiasts know that the temperature of your espresso machine is an important factor in the production of a good cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190 and 196 degrees. To get this temperature, you need an espresso maker with a reliable thermoblock, thermocoil or thermoblock and a boiler that is sized correctly.
In addition, it is crucial to warm your portafilter, espresso machine, and cup prior to making a shot. Beginner espresso makers often make the mistake of not heating their machine prior to making a shot. This is the reason you should always go through the instruction manual prior to making use of your espresso maker for the first time.
Grind
A barista machine must give you a range of grind settings so you can have the greatest control over home espresso machine the final cup of espresso. Some machines have an analog gauge that looks cool and helps you develop your brewing capabilities. You should aim to maintain the pressure at nine bars throughout the entire brewing process. While this machine does not hit the mark, it's quite close and will serve you well.
Another wonderful feature of this machine is the built-in burr grinder. This feature is great for novices because it doesn't mean the need for an additional grinder. The stainless steel conical grinder comes with 18 settings, which range from "coarse to fine."
This grinder isn't as good as a standalone unit, however, it's a decent start and will get you on the right track to making quality espresso shots. It's easy to clean and you'll be able to put the grinder on hold during the process of grinding to avoid creating a mountainous amount of grounds in your portafilter when it is being tamped.
This is a beautiful and functional machine that lets you to experience the thrill of becoming a barista from home. It's a great choice for anyone who would like to be able to revisit the fond memories of pouring microfoam into their morning coffee by locking a portafilter to the grouphead, and then tamping with precision. A bean-to-cup machine is a good option for those who are looking for convenience.
Water
Water is a tricky thing to master. The trick is to find the right balance. Too much caffeine can cause mineral deposits to develop in your machine. But too little will result in a weaker cup of espresso.
The ideal espresso water has an alkalinity and hardness that is low level. It is best to use a water purifier that does not contain chlorine and adds a tiny amount (TDS) of total dissolved substances that add calcium and magnesium. This will help you achieve a good balance between hardness and acidity and will also prevent the need to decalcify.
Using a high quality filtered water is crucial to your machine's overall health and the taste of the coffee it produces. Descaling products must be regularly used according to the hardness and usage of your machine. These products come in liquid, powder and tab forms and are available in many hardware stores.
The Breville Barista Express is a high-end, premium home espresso machine that was designed to bring the experience of a cafe to your home. It offers more advanced features over other basic machines which are targeted at coffee lovers who want to perfect their technique and improve their craft. The thermocoil heater that has an integrated PID controller, situated on the group head which is heated continuously which makes it simple to regulate your brewing temperatures. This is a big advantage over other entry-level models which require you to spend a lot of time "temperature-surfing" to get an even espresso shot.
