What to Look For in a Barista Espresso Machine
The espresso machine is among the most complicated coffee machines in the world. It is comprised of three main parts. The bottom contains the water and the middle the filter-basket.

Pressure
If you are a coffee enthusiast, you will know that the pressure of your machine is a major factor in the quality of your drinks. If you're looking for an even layer of crema or the perfect balance of acidity and flavor the pressure of your espresso machine is crucial to making great espresso.
BARs (Barometric pressure) is the force your espresso machine exerts on the grounds of your coffee while delivering high-pressure water. Your espresso machine is pushing heated water through the grounds of the coffee at a rate nine times that of Earth's current atmosphere pressure.
The pressure of your espresso machine is important because it's what allows the water to flow through the grounds of coffee at the proper speed and with the right intensity. If the pressure isn't high enough the flavors and oils 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 a weak, over-extracted cup of espresso.
You can control the pressure of your espresso maker by adjusting the screw that is attached to the espresso pump. Commercial machines and high-end home appliances have rotating pumps that can be adjusted in pressure. But for the more affordable home machines that utilize an oscillating pump, changing the pressure is impossible without involving DIY hacks. However, companies like Cafflano are working on technology that uses Pascal's Principle to maintain pressure within the portafilter during the brewing process.
Temperature
The temperature is one of the most crucial factors to an espresso shot that is perfect. If the water is too hot, it could scorch the coffee grounds and create a bitter coffee. The ideal temperature for extraction is around 200 degrees Fahrenheit which allows the water to extract all of the coffee's desirable flavors without scalding the grounds or over-extracting.
The best espresso machines will include a thermoblock or thermocoil which will heat the water, and keeps it at a steady temperature throughout the whole extraction cycle. The Breville Barista Express, for example, has a PID (Proportional Integral Derivative) system which constantly checks the temperature of the water and adjusts it as needed making sure that the brew head stays at a perfect temperature for extraction.
The majority of coffee drinkers are aware that the temperature of your espresso maker is a crucial factor in making a quality cup of coffee. The ideal temperature for espresso is between Fahrenheit between 190 and 196 degrees. To attain this, your machine must be equipped with a reliable thermoblock or thermocoil and the boiler needs to be sized appropriately.
It is also crucial to warm your machine, portafilter, and cup before you make an espresso. The failure to preheat is among the most common mistakes that can be committed by novice espresso makers. This is the reason why you should always study the instruction manual before making use of your espresso maker for the first time.
Grind
A barista espresso machine must provide a variety grind settings to give you the most control over your final cup of coffee. Some machines come with an analog pressure gauge that looks cool and can help you gain knowledge about the brewing process. You should aim to maintain the pressure of nine bars throughout the process of brewing. While this machine does not hit that target, it is close enough and will serve you well.
A built-in grinder is another nice touch. This is a great feature for people who are new to espresso since it eliminates the need to purchase an additional burr grinder. The stainless steel conical grinder has 18 settings that range from "coarse to fine."
It's not as efficient as a standalone but it can get you started on the right track to make great espresso shots. It's easy to clean and you'll be able to pause the grinder during the grinding process to avoid accumulating an overwhelming amount of ground in your portafilter when it is being tamped.
This gorgeous and useful machine will let you enjoy the barista experience in your home. It's an excellent choice for those who wish to be able to look back on the fond memories of pouring microfoam into their morning cup of joe, locking a portafilter into the grouphead, and tamping with precision. If you're looking for convenience, a bean-to- cup machine might be a better choice.
Water
Water is a difficult thing to master. Finding the right balance is essential. Too much can cause mineral deposits to develop in your machine. But too little can result in a weaker cup of espresso.
The ideal water for espresso is soft 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 that add calcium and magnesium. This will ensure an optimal balance between hardness and acidity and will also prevent the need to decalcify.
Using a high-quality filter water is essential to your machine's longevity health and the flavor of the coffee it makes. Depending on the use and the hardness of your machine, you should make use of a descaling product on a regular schedule. The products are available in powder, liquid and tab forms and can be found at many hardware stores.
The Breville Barista Express, a premium espresso machine for home use is designed to bring the café experience into your home. It comes with more advanced features in comparison to other machines for beginners and is targeted at those who are looking to refine their technique and perfect 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 is a big advantage over other basic models that require much time "temperature-surfing" to ensure an even shot of espresso.
