What to Look For in a Barista Espresso Machine

The espresso machine is one of the most intricate coffee machines available. It consists of three main parts. The bottom holds the water and the middle is a basin for filtration with a metal filter.

This machine was a huge success and helped to popularize home barista espresso. It features a low pressure pre-infusion, a 2.2L boiler and brewing pressure of 9 bar.

Pressure

If you're an avid coffee drinker, then you'll be aware that the pressure of your machine is a key factor in the quality of your drinks. 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 machine is crucial to making great espresso.

BARs (Barometric pressure) is the amount of force that your espresso machine applies to the grounds of your coffee while delivering high-pressure water. 9 BARs means that the espresso machine is pushing heated water through the ground coffee at 9 times the Earth's current atmospheric pressure.

The pressure of your espresso machine is vital as it allows the water to move through the grounds of your coffee with the right speed and in the right amount. If the pressure is too low, the dissolved oils and flavors won't be properly extracted. 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, over-extracted cup of espresso.

The pressure of your espresso machine can be adjusted by turning the screw found on the espresso pump. Commercial machines and top-end home machines come with rotating pumps that can be adjusted in pressure. For the cheaper home machines espresso that use a vibrating pump, adjusting the pressure is difficult without using DIY hacks. Companies such as Cafflano, however, are working on technology that is based on Pascal's Principle to ensure the pressure within the portafilter all through the beer making process.

Temperature

Temperature is one of the most important elements in the perfect espresso shot. If the water is too hot, it will scorch the coffee grounds and result in an over-extracted bitter brew. The ideal temperature for extraction is around 200 degrees Fahrenheit which allows the water to extract all of the coffee's desirable flavors without scorching the grounds or over-extracting.

The top espresso machines come with the thermoblock, or thermocoil that heats water and keeps it at a constant temperature throughout the extraction cycle. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system which constantly monitors the water temperature and adjusts if needed, ensuring that the brewhead stays at the ideal temperature for extraction.

Most coffee lovers know that the temperature of the espresso makers machine is essential to making a great cup of coffee. The ideal temperature for brewing espresso is between 190 and 196 degrees Fahrenheit. To achieve this, your espresso machine must be equipped with a reliable thermoblock or thermocoil and the boiler needs to be sized appropriately.

It is also important to heat your machine, portafilter, and cup prior to making shots. Beginners often make the mistake of not preheating their machine. It is recommended to read your cheap espresso machine machine's instructions before you begin using it for the first time.

Grind

A barista espresso machine must also offer a variety of grind settings to give you the most control over the final cup of coffee. Some machines include an analog pressure gauge which is cool and can help you gain knowledge about the brewing process. Ideally, you should reach around nine bars of pressure and keep that throughout the brew cycle. This machine is near reaching that goal.

Another nice touch on this machine is the built-in burr grinder. This is a great feature for those who are new to espresso because it eliminates the need to pay for an additional burr grinder. The stainless steel conical grinder comes with 18 settings that range from "coarse to fine."

It's not as good as a stand-alone unit, but it's an excellent start and will put you on the path to creating quality espresso shots. It's easy-to-clean and you can pause the grinder during the process of grinding to avoid accumulating a huge amount of ground in your portafilter when it is being stamped.

This stunning and practical machine will allow you to be a barista at your own home. This is a great choice for those who want to remember the thrill of pouring microfoam in their morning coffee and locking the portafilter into the grouphead's head and tamping the coffee with precision. For those who simply 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 vital. Too much caffeine can cause mineral deposits to build up in your machine, however too little and you'll struggle make a full cup of espresso.

The ideal water for espresso has low alkalinity and hardness level. This is best achieved by using an effective water filtering system that does away with chlorine and then adds back a small amount of total dissolving solids (TDS) to add calcium and magnesium to the mix. This will give you a good balance between acidity and hardness and also avoid the need to decalcify.

It is essential to use filtered water of good quality to ensure the health and flavor of your machine. Depending on the use and hardness of your machine you should make use of descaling products on a regular schedule. They are available in powder, liquid or tab form at a majority of hardware stores.

The Breville Barista Express, a top-of-the-line home espresso machine is designed to bring the café experience into your home. It is more sophisticated than other espresso machines that are geared towards coffee lovers who wish to refine their technique and perfect their craft. The thermocoil heating system with an integrated PID controller located on the group head that is actively heated, makes it easy to control your brewing temperature. This can be a huge benefit over other models that require longer "temperature surfing" to ensure a consistent shot of espresso machine with grinder.
