What to Look For in a Barista Espresso Machine
The espresso machine is one of the most intricate coffee machines around the globe. It consists of three main components. The bottom holds the water and the middle is a filtration basin with a metal filter.
This machine was a big success and was instrumental in bringing home barista espresso. Features include 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 aspect in how well your drinks taste. The pressure of your machine is vital to brewing great coffee, whether you're seeking a thick layer or the perfect balance of acidity and flavor.
BARs (Barometric Pressure) refer to the amount of force that is applied to the coffee grounds when your espresso machine is delivering its high-pressure water. 9 BARs mean that your espresso machine is forcing heated water through the coffee grounds at 9 times the Earth's current atmospheric pressure.
The pressure of your machine is crucial because it allows water to flow through coffee grounds at the right speed and intensity. If the pressure is too low, the flavors and oils that are dissolved aren't extracted properly. On the other however, if the pressure is too high, the water will be pushed through the coffee grounds too quickly and you'll end with a weak and over-extracted cup of espresso.
You can regulate the pressure of your espresso maker by adjusting the screw of the espresso maker. Commercial machines and top-end home machines feature pumps that rotate with adjustable pressure. For the cheaper home machines that have a vibrating motor, it is impossible to alter the pressure without DIY hacks. Companies like Cafflano however, are developing technology that utilizes Pascal's Principle to ensure the pressure within the portafilter all through the making process.
Temperature
Temperature is among the most important elements in the perfect espresso shot. If the water is too hot, it could heat the coffee grounds and create an over-extracted bitter brew. The ideal temperature for extraction is about 200 degrees Fahrenheit which allows the water to extract all the desired flavors of coffee without scorching the grounds, or over-extracting.
The best espresso machines include thermoblocks, also known as thermocoils which heats the water and maintains it at an even temperature throughout the extraction process. The Breville Barista Express, for example, features a PID (Proportional Integral Derivative) system that constantly monitors the temperature of water and adjusts it as needed to ensure that the brewhead stays at the right temperature to extract the coffee.
Most coffee lovers are aware that the temperature of the espresso machine is vital to brewing a great cup of coffee. The ideal temperature for espresso is between between 190 and 196. To achieve this, you need an espresso maker with a reliable thermoblock, thermocoil and a boiler that is properly sized.
In addition, it is important to pre-heat your portafilter, machine, and the cup prior to making the shot. Espresso makers who are beginners often make the mistake of not preheating their equipment. It is recommended to read your espresso machine's instructions before you use it for the first time.
Grind
A barista espresso machine must also provide a variety grind settings for you to have the most control over your final cup of coffee. Some machines have an analog pressure gauge that looks cool and can help you learn about your brewing skills. The ideal goal is to get around nine bars of pressure, and keep this throughout the entire brewing process. Although this machine can't reach the desired pressure, it's pretty close and will serve you well.
Another nice touch on this machine is its built-in burr grinder. This feature is perfect for beginners since it eliminates having to purchase an additional grinder. The grinder is a conical stainless steel unit with 18 settings from "coarse" to "fine."
It's not as effective as a stand-alone unit, but it's a good start and will get you on your way to brewing quality espresso shots. It's easy to clean and you'll be able to stop the grinder in the grinding process to avoid accumulating a huge amount of grounds in your portafilter when it is being put through the tamper.
This stunning and practical machine will allow you to be a barista at your own home. It's an excellent choice for anyone who wants to be able to look back at the moments of pouring microfoam into their morning cup of joe, locking a portafilter into the grouphead, and then tamping with precision. For those who want convenience, a bean to cup machine could be a better choice.
Water
Water can be a challenging thing to master. The trick is finding the right balance. Too much can result in mineral deposits on the machine, but too little and you'll struggle to enjoy a satisfying cup of espresso.
The best espresso water has low alkalinity coffee machine espresso and hardness level. It is best to use a water filter that does not contain chlorine and adds a small amount (TDS) of total dissolved substances to add calcium and magnesium. This will result in a good balance of alkalinity and hardness and reduce the necessity of decalcifying your equipment.
It is vital to make sure you use water that has been filtered to a high-quality for the health and flavor of your machine. Based on the usage and hardness of your machine you should make use of descaling products regularly. They are available in liquid, powder or tab form at most hardware stores.
The Breville Barista Express, a premium espresso machine for home use is designed to bring the café experience to your home. It has more advanced features than other machines for beginners which are targeted at coffee enthusiasts who wish to improve their technique and perfect their craft. The thermocoil heating system with an integrated PID controller, centered on the group head that is continuously heated, makes it easy to regulate your brewing temperatures. This is a significant advantage over competing entry-level models which require longer "temperature surfing" to ensure an espresso shot that is consistent.
