What to Look For in a Barista Espresso Machine
The espresso machine is one of the most intricate coffee machines in the world. It is comprised of three main components. The bottom holds the water while the middle part is a filter-basket with a metal filter.
This machine was a huge hit and helped to popularize the prosumer (home barista) espresso market. Features include a 2.2L steam boiler, a low pressure pre-infusion and 9 bar brewing pressure.
Pressure
If you're serious about your coffee then you're aware that the pressure of your espresso maker is a crucial factor in how well your drinks come out. The pressure of your machine is vital to making excellent coffee, whether you're looking for a dense layer or the perfect balance of flavor and acidity.
BARs (Barometric Pressure) refer to the amount of 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 coffee grounds at 9 times the Earth's current atmospheric pressure.
The pressure of the espresso machine is crucial because it's what allows the water to flow through the grounds of your coffee with the right speed and in the right amount. If the pressure isn't sufficient the oils and flavors won't be 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 up with a weak and over-extracted cup of espresso.
The pressure of your espresso machine can be controlled by adjusting the screw that is located on the espresso pump. Commercial machines and top-end home machines have pumps that rotate with adjustable pressure. But for the more affordable home machines that have the pump that vibrates, adjusting the pressure isn't possible without involving DIY hacks. Companies like Cafflano however, are developing technology that uses Pascal's Principle to ensure the pressure within the portafilter all through the fermentation process.
Temperature
The temperature is one of the most important factors in brewing an espresso shot that is perfect. Hot water can cause burning of the grounds of coffee, which can result in a bitter espresso. The ideal extraction temperature is about 200 degrees Fahrenheit which allows the water to extract all of the desired coffee flavors without scorching the grounds, or over-extracting.
The best espresso machines have a thermoblock or thermocoil which heats the water and keeps it at a steady temperature throughout the whole extraction process. The Breville Barista Express, for example, has a PID (Proportional Integral Derivative) system which constantly monitors the water temperature and adjusts as necessary making sure that the brew head remains at a perfect temperature for extraction.
The majority of coffee drinkers know that the temperature of an espresso machine is vital to brewing a great cup of coffee. The ideal temperature for espresso is between 190 and 196. To achieve this, you require an espresso machine with a top thermoblock, thermocoil or thermoblock and a boiler that is appropriately sized.
Additionally, it is important to preheat your espresso maker, portafilter and cup before you make an espresso. Beginners often make the mistake of not preheating their machine. This is why it is important to always read the instruction manual before making espresso for the first time.
Grind
A barista espresso machine should also offer a variety of grind settings to give you the greatest control over the final cup of coffee. Some machines come with an analog pressure gauge that looks cool and can help you learn about your brewing techniques. You should aim to maintain the pressure at nine bars throughout the brewing process. This machine is near reaching that goal.
Another nice touch on this machine is a built-in burr grinder. This is an excellent feature for newbies to espresso as it eliminates the need to purchase a separate burr grinder. The stainless steel conical grinder has 18 settings, which range from "coarse to fine."
The grinder isn't as effective as a standalone but it can help you get to the right path to making excellent 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 accumulating an overwhelming amount of ground in your portafilter when it is being tamped.
This is a stunning and functional machine that will allow you to experience the thrill of being a barista home. It's a great option for anyone who would like to to look back at the fond memories of pouring microfoam into your morning cup of coffee and locking a portafilter in the grouphead, and then tamping with precision. A bean to cup machine is a good option for those who want convenience.
Water
Water is a tricky thing to master. Finding the right balance is crucial. Too much can cause mineral deposits to form in your machine. But too little can result in an espresso cup that is weaker.
The ideal water for espresso is soft and high in alkalinity. This is best achieved using an water filter system that removes chlorine and puts back in a small amount of total dissolved solids (TDS) to add some calcium and magnesium to the mix. This will create an optimal balance between alkalinity and hardness and reduce the need to decalcify your machine.
A high-quality, filtered water is crucial for your machine's long-term health and the taste of the coffee it produces. Based on the usage and hardness of your machine you should make use of descaling products regularly. These products are available as tab, liquid, or powder in a variety of hardware stores.
The Breville Barista Express, a luxury high-end home espresso machine designed to bring the café experience espresso coffee machine home into your home. It is equipped with more advanced features when compared to other machines for beginners, and is geared towards coffee enthusiasts who want refine their technique and perfect the craft. The thermocoil heater, with an integrated PID controller located on the group head which is constantly heated, makes it easy to regulate your brewing temperature. This can be a huge advantage over the other models that require more time "temperature surfing" to achieve an even shot of espresso.
