What to Look For in a Barista Espresso Machine

The espresso machine is one of the most complex coffee machines around the globe. It is made up of three major components. The base holds the water and the middle is a filtration basin with a metal filter.

This machine was a huge hit and was instrumental in establishing the prosumer (home barista) espresso market. It features a low pressure pre-infusion as well as an 2.2L boiler and brewing pressure of 9 bar.

Pressure

If you're a coffee lover, you'll realize that the pressure of your machine is a major element in the quality of your beverages. The pressure of your machine is crucial in brewing excellent coffee whether you're seeking a thick layer or the perfect balance of flavor and acidity.

BARs (Barometric Pressure) refer to the amount of force that is imposed on the grounds of your coffee when your espresso machine is delivering its high-pressure water. 9 BARs indicates that your espresso machine is pushing heated water through the ground coffee at an amount of nine times the current atmospheric pressure.

The pressure of your espresso machine is important as it allows the water to flow through the grounds of your coffee with the right speed and intensity. If the pressure is too low, the dissolved oils and flavors won't be extracted properly. On the other however, if the pressure is too high the water will be forced through the coffee grounds too fast and you'll end up with a weak and over-extracted cup of espresso.

You can regulate the pressure of your espresso maker by adjusting the screw that is attached to the espresso pump. Commercial and high-end home machines come with pumps that rotate with adjustable pressure. For home machines that are less expensive, which use a vibrating motor, it is impossible to adjust the pressure without DIY hacks. Companies like Cafflano, however, are working on technology which uses Pascal's Principle to ensure pressure in the portafilter during the beer making process.

Temperature

Temperature is among the most important elements in a perfect espresso shot. If the water is too hot, it will ignite the coffee grounds and create an over-extracted bitter coffee. The optimal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all desired coffee flavors without scorching the grounds or causing excessive extraction.

The top espresso machines home machines come with a thermoblock, or thermocoil which heats the water and maintains it at the same temperature throughout the extraction process. The Breville Barista Express, for example, has a PID (Proportional Integral Derivative) system which constantly monitors the temperature of the water and adjusts if needed to ensure that the brewhead remains at the perfect temperature for extraction.

Most coffee lovers know that the temperature of your espresso machine is an important factor in making a quality cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190 and 196. To achieve this, you need a machine with a good thermoblock, thermocoil and a boiler that is sized correctly.

It is also essential to heat up your machine or portafilter before making the espresso. Beginners often make the mistake of not preheating their machine. It is advisable to read your espresso machine's instructions before you start using it for the first time.

Grind

A barista machine should offer you a variety of grind settings so that you have the maximum control over the final cup of espresso. Some machines come with an analog pressure gauge, which looks cool and can help you learn about your brewing techniques. It is recommended to maintain the pressure at nine bars throughout the brewing process. Although this machine isn't hitting this mark, it's close enough and will serve you well.

Another excellent feature of this machine is that it has a built-in burr grinder. This is a fantastic feature for newbies to espresso as it will not require you to shell out money for an additional burr grinder. The grinder is a stainless steel conical device that has 18 settings from "coarse" to "fine."

It's not as efficient as a standalone unit, but it can get you started on the right track to making great espresso shots. It's easy to clean and you can even pause it while grinding and avoid creating a pile of ground that will fall over your portafilter while on its way to making tamps.

This gorgeous and useful machine lets you experience being a barista in your home. This is an excellent option for those who wish to relive the thrill of pouring microfoam in their morning cup of coffee and locking the portafilter into the grouphead's head and tamping it with precision. A bean-to-cup machine is a great option for those who want convenience.

Water

It is a challenge to master. It's important to find the right balance. Too much can cause mineral deposits to form in your machine. But too little will result in a weaker cup of espresso.

The ideal water for espresso is low in hardness and high in alkalinity. It is best bean to cup espresso machine to use a water purifier that does not contain chlorine and adds a tiny amount (TDS) of total dissolved substances in order to add calcium and magnesium. This will create an optimal balance between alkalinity and hardness, and will reduce the necessity of decalcifying your machine.

Using high-quality filtered water is vital to your machine's long term health and the flavor of the coffee it makes. Based on the type of use and the hardness of the machine, you should make use of a descaling product regularly. These products come in powder, liquid and tab forms and are available at all hardware stores.

The Breville Barista Express is a premium, high-end home espresso machine designed to bring the experience of a cafe into your home. It comes with more advanced features than other machines for beginners, and is targeted at those who are looking to refine their technique and master the craft. The thermocoil heating system that comes with integrated PID controller, centered on the active heated group head makes it easy to control your brewing temperature. This can be a huge advantage over competing entry-level models that require more time "temperature surfing" to achieve a consistent shot of espresso.
