What to Look For in a Barista Espresso Machine
The espresso machine is one of the most complicated coffee machines in the world. It is made up of three main parts. The bottom houses the water and the middle is the filter-basket.
This machine was a huge success and was instrumental in establishing the prosumer (home barista) espresso market. It features a 2.2L steam boiler, low pressure pre-infusion and 9 bar pressure for brewing.
Pressure
If you're serious about coffee and espresso, then you're aware that the pressure of your espresso maker is an essential factor 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 a perfect balance of flavor and acidity.
BARs (Barometric pressure) is the amount of force that your espresso machine applies to the grounds of the coffee while delivering high-pressure water. 9 BARs means that your 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 your machine is essential because it allows the water to flow through coffee grounds at a proper speed and intensity. If the pressure isn't sufficient, the oils and flavors will not be extracted properly. If the pressure is too low, the flavors and oils dissolved won't be extracted properly.
You can control the pressure of your espresso maker by changing the screw that is attached to the espresso pump. Commercial machines and a few high-end home appliances use the rotary pumps, which are adjustable. For the cheaper home machines that utilize a vibration motor, it's impossible to adjust the pressure without hacks. However, companies like Cafflano are working on technology that employs Pascal's Principle to maintain pressure inside the portafilter during the making process.
Temperature
The temperature is among the most important factors in brewing a great espresso shot. Too hot water can burn the grounds of the coffee, leading to bitter drink. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all desired coffee flavors without burning the grounds or excessively extracting.
The best espresso machines include a thermoblock, or thermocoil, which heats water and keeps it at an even temperature throughout the extraction cycle. The Breville Barista Express, for instance, is equipped with a PID (Proportional Integral Derivative) system which constantly monitors the temperature of water and adjusts according to the need, ensuring that the brew head stays at the right temperature for extraction.
Most coffee lovers know that the temperature of your espresso maker is an important factor to brewing a high-quality cup of coffee. The ideal brewing temperature for espresso is between 190 to 196 degrees Fahrenheit. To achieve this, your espresso machine must have a quality thermoblock or thermocoil and the boiler needs to be sized appropriately.
It is also essential to heat up your machine as well as the portafilter and cup prior to making a shot. Failure to preheat is one of the most frequent mistakes made by novice espresso makers. This is why you should always study the instruction manual before making espresso for the first time.
Grind
A barista machine must give you a range of grind settings so that you have the maximum control over your final cup of espresso. Some machines include an analog pressure gauge, which is cool and can help you learn about your brewing techniques. The goal is to maintain the pressure at nine bars throughout the entire brewing process. While this machine doesn't hit this mark, it's pretty close and will be able to serve you well.
A built-in burr mill is also a great feature. This feature is great for novices because it doesn't mean the need for an additional grinder. The stainless steel conical grinder has 18 settings that range from "coarse to fine."
It's not as effective as a stand-alone device, read more but it's an excellent start and will put you on your way to making high-quality espresso shots. It's easy to clean, and you can put the grinder on hold during the process of grinding to avoid accumulating an overwhelming amount of grounds in your portafilter when it's being tamped.
This is a stunning and functional machine that allows you to experience the excitement of being a barista home. It's an excellent choice for anyone who would like to to revisit the fond memories of pouring microfoam into your morning cup of coffee by locking a portafilter to the grouphead, and then tamping with precision. For those who just want convenience, a bean to cup machine might be a better choice.
Water
Water can be a tricky thing to master. Finding the right balance is key. Too much caffeine can cause mineral deposits in your machine, while too little and you'll struggle enjoy a satisfying cup of espresso.
The ideal water for espresso is soft and high in alkalinity. It is best to use a filter that bypasses chlorine and adds a tiny amount (TDS) of total dissolved substances to provide calcium and magnesium. This will give you the right balance between hardness and acidity, and prevent the need to decalcify.
It is important to make sure you use water that has been filtered to a high quality for the health and flavor of your machine. Descaling products must be regularly used depending on the hardness and usage of your machine. These products are available as tab, liquid or powder form at a majority of hardware stores.
The Breville Barista Express is a high-end, luxury home espresso machine designed to bring the experience of a cafe inside your home. It comes with more advanced features compared to other espresso machines that are beginner-friendly, and is targeted at coffee enthusiasts who want refine their technique and perfect their craft. The thermocoil heater, with an integrated PID controller, located on the group head that is actively heated and allows you to regulate your brewing temperature. This is a major advantage over other entry-level models that will require you to spend a lot of time "temperature-surfing" to get a consistent espresso shot.
