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 made up of three major components. The bottom is where the water goes and the middle is the filter-basket.

This machine was a big hit and helped popularize the home barista espresso. It features a 2.2L steam boiler, low pressure pre-infusion & 9 bar brewing pressure.

Pressure

If you are an avid coffee drinker, you will know that the pressure of your espresso machine is a crucial element in the quality of your drinks. The pressure of your machine is essential for making great coffee, whether you're seeking a thick layer or a perfect balance of acidity and flavor.

BARs (Barometric Pressure) refer to the force applied to the coffee grounds when your espresso machine is pumping out its high-pressure water. 9 BARs mean that your espresso machine is forcing heated water through the coffee grounds at a rate of nine times the current atmospheric pressure.

The pressure of your espresso machine is important as it allows the water to move through the coffee grounds at the right speed and with the right intensity. If the pressure is low the oils and flavors aren't extracted properly. If the pressure is too low the flavors and oils dissolved will not 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 as well as some high-end home machines have the rotary pumps, which are adjustable. For home-based machines that use a vibrating motor, it's not possible to adjust the pressure without DIY hacks. However, companies such as Cafflano are developing technology that makes use of Pascal's Principle to create maintained pressure in the portafilter during the fermentation process.

Temperature

The temperature is among the most important aspects for a great espresso shot. The water that is too hot can scorch the grounds of coffee, which can result in a bitter coffee. The ideal extraction temperature is about 200 degrees Fahrenheit, which allows the water to extract all of the coffee's desirable flavors without scalding the grounds or over-extracting.

The top espresso machines come with thermoblocks, also known as thermocoils, which heats water and keeps it at an unchanging temperature throughout the extraction process. The Breville Barista Express has a PID system (Proportional Integral Derived) which continuously monitors and adjusts the water temperature. This ensures that the brewhead remains at the correct temperature for extraction.

Many coffee drinkers are aware that the temperature of the espresso home machine maker is vital to brewing a great cup of coffee. The ideal temperature for brewing espresso is between 190 to 196 degrees Fahrenheit. In order to achieve this, your machine must have a good thermoblock or thermocoil and the boiler must be sized to the correct size.

It is also important to pre-heat your machine as well as the portafilter and cup prior to making a shot. Beginners often make the mistake of not heating their machine prior to making a shot. This is the reason you should always review the instruction manual before making use of your espresso maker for the first time.

Grind

A barista espresso machine must also provide a variety grind settings for you to have the most control over the final cup of coffee. Some machines have an analog gauge that is cool and helps you improve your brewing skills. You should strive to maintain the pressure of nine bars throughout the brewing process. Although this machine isn't hitting that target, it is close enough and will serve you well.

A built-in grinder is another nice touch. This feature is ideal for novices because it doesn't mean the need for a separate grinder. The grinder is a stainless steel conical device that has 18 settings from "coarse" to "fine."

This grinder isn't quite as effective as a stand-alone device, but it's a good start and will get you well on your way to brewing quality espresso machine espresso shots. It's easy to clean and you can also pause it while grinding and avoid creating a pile of ground that can spill over your portafilter while on its way to grinding.

This gorgeous and practical machine will allow you to be a barista at your own home. It's a great option for those who wish to to look back at the moments 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 great option for those looking for a simple and convenient solution.

Water

Water can be a difficult thing to master. Finding the right balance is vital. Too much caffeine can result in mineral deposits on your machine, however too little and you'll struggle make a full cup of espresso.

The ideal espresso water is low in hardness and high in alkalinity. It is best to use a water purifier that removes chlorine and adds a small amount (TDS) of total dissolved substances to add calcium and magnesium. This will help you achieve a good balance between acidity and hardness and also avoid the necessity of decalcifying.

It is vital to make sure you use water that has been filtered to a good quality to ensure the health and taste of your machine. Descaling products should be used on a regular basis depending on the strength and use of your machine. These products come in liquid, powder and tab forms and are available at most hardware stores.

The Breville Barista Express is a high-end, premium espresso machine for home use that is designed to bring the experience of a cafe into your home. It comes with more advanced features in comparison to other machines for beginners and is targeted at coffee lovers who want to refine their technique and perfect their craft. The thermocoil heater that has an integrated PID controller, located on the group head which is actively heated and allows you to regulate your brewing temperature. This is an enormous advantage over the other models that require longer "temperature surfing" to get an professional espresso maker shot that is consistent.
