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 main components. The bottom holds the water while the middle is a basin for filtration with a metal filter.

This machine was a huge success and helped spread the prosumer (home barista) espresso market. It features a 2.2L steam boiler, low pressure pre-infusion and 9 bar brewing pressure.

Pressure

If you are an avid coffee drinker, then you'll realize that the pressure of your machine is a crucial factor in the quality of your coffee. It doesn't matter if you're seeking a thick layer of crema, or the perfect balance of flavor and acidity the pressure of your espresso maker is crucial to making excellent espresso.

BARs (Barometric Pressure) refer to the force that is applied to the coffee grounds when your espresso machine is pumping out its high-pressure water. Your espresso machine is pushing heated water through the grounds of coffee at nine times the Earth's current atmospheric pressure.

The pressure of your machine is crucial because it allows the water to pass through the coffee grounds at the proper speed and intensity. If the pressure is too low the flavors and oils dissolved will not be extracted properly. On the other side, if the pressure is too high the water will be pushed through the coffee grounds too fast and you'll end with an over-extracted, weak cup of espresso.

You can control the pressure of your espresso maker by changing the screw on the espresso pump. Commercial machines and some high-end home appliances use the rotary pumps, which are adjustable. For home machines that are less expensive, which use a vibrating motor, it is impossible to alter the pressure without hacks. Companies like Cafflano however, are working on technology that utilizes Pascal's Principle to ensure pressure within the portafilter throughout the brewing process.

Temperature

Temperature is among the most crucial factors in a great espresso shot. If the water is too hot, it can scorch the coffee grounds and produce an over-extracted bitter drink. The ideal extraction temperature is 200 degrees Fahrenheit which allows the water to extract all the desired flavors of coffee without scorching the grounds, or over-extracting.

The top espresso machines come with the thermoblock, also known as a thermocoil, which heats water and maintains it at the same temperature throughout the extraction. The Breville Barista Express, for example, has PID (Proportional Integral Derivative) system which constantly monitors the temperature of the water and adjusts if needed, ensuring that the brew head remains at the perfect temperature to extract the coffee.

Many coffee drinkers are aware that the temperature of the espresso machine is crucial to a good cup of coffee. The ideal brewing temperature for espresso is between 190 to 196 degrees Fahrenheit. To get this temperature, you need an espresso machine that has a high-quality thermoblock, thermocoil and boiler that is appropriately sized.

It is also important to pre-heat your portafilter, machine, and cup prior to taking espresso. Beginners who make espresso often make the mistake of not heating their machine prior to making a shot. This is the reason you should always read the instruction manual before using your espresso machine for the first time.

Grind

A barista machine ought to give you a variety of grind settings to ensure that you have the best coffee espresso machine control over your final cup of espresso. Some machines have an analog pressure gauge, that is stylish and can help you learn about your brewing skills. It is recommended to maintain the pressure at nine bars throughout the process of brewing. This machine is very close to reaching that goal.

A built-in grinder is another good feature. This feature is great for beginners because it eliminates the need to purchase a separate grinder. The grinder is a stainless steel conical device with 18 settings ranging from "coarse" to "fine."

This grinder isn't the same as a stand-alone device, however, it's a decent beginning and will get you well on your way to making high-quality espresso machine with milk frother shots. It's easy to clean and you can stop the grinder during the process of grinding to avoid creating a mountainous amount of grounds on your portafilter as it's being stamped.

This is a stunning and functional machine that allows you to feel the excitement of becoming a barista from home. It's a great option for those who wish to to look back on the moments of pouring microfoam into their morning coffee by locking a portafilter to the grouphead, and tamping with precision. For those who just want convenience, a bean to cup machine could be the better choice.

Water

Water is a tricky thing to master. It's important to find the appropriate balance. Too much can cause mineral deposits to build up in your machine, however too little and you'll struggle to make a full cup of espresso.

The perfect water for espresso is low in hardness and high in alkalinity. It is best to use a water filter that removes chlorine and adds a small amount (TDS) of total dissolved substances to provide calcium and magnesium. This will help you achieve an ideal balance between acidity and hardness, and prevent the need to decalcify.

It is essential to use water that is filtered and of good quality to ensure the health and taste of your machine. Depending on the use and hardness of your machine you should use a descaling product on a regular basis. The products are available in powder, liquid and tab forms and can be found in all hardware stores.

The Breville barista espresso coffee machine Express is a high-end, premium home espresso machine designed to bring the cafe experience into the home. It has more advanced features than other beginner machines, and is geared towards coffee enthusiasts who want refine their technique and master the art of coffee. The thermocoil heating mechanism with an integrated PID controller mounted on the actively heated group head makes it easy to regulate the temperature of your coffee. This can be a huge advantage over other entry-level models that require more time "temperature surfing" to get a consistent shot of espresso.
