5 Laws That'll Help The Barista Espresso Machine Industry
What to Look For in a Barista Espresso Machine
The espresso machine is one of the most complex coffee machines around the world. It is made up of three main parts. The bottom holds the water, and the middle is a filter-basket with a filter made of metal.
This machine was a huge success and helped to popularize the prosumer (home barista) espresso market. Its features include a low-pressure pre-infusion, the 2.2L boiler and brewing pressure of 9 bar.

If you're an avid coffee drinker, then you will know that the pressure of your espresso machine is a crucial element in the quality of your coffee. Whether you're looking for a thick layer of crema or right balance of flavor and acidity, the pressure of your espresso machine is the most important factor in brewing excellent espresso.
BARs (Barometric Pressure) refer to the amount of force that is applied to the coffee grounds when your espresso machine is delivering its 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 machine is important because it allows water to pass through the coffee grounds at the correct speed and intensity. If the pressure is too low the dissolved oils and flavors aren't extracted properly. On the other however, if the pressure is too high, the water will be pushed through the coffee grounds too fast, and you'll end up with a weak and over-extracted cup of espresso.
You can control the pressure of your espresso maker by changing the screw on the espresso pump. Commercial and high-end home machines have rotating pumps that can be adjusted in pressure. For the more affordable home machines that have the vibrating pump, altering the pressure is impossible without involving DIY hacks. However, companies like Cafflano are developing technology that uses Pascal's Principle to maintain pressure inside the portafilter throughout the making process.
Temperature
The temperature is one of the most crucial factors to a great espresso shot. Too hot water can burn the grounds of coffee, which can result in a bitter brew. The ideal temperature for extraction is 200 degrees Fahrenheit. This lets the water extract all the desired coffee flavors without burning the grounds or over-extracting.
The top espresso machines feature a thermoblock, or thermocoil which heats the water and keeps it at a stable temperature throughout the whole extraction process. The Breville Barista Express, for instance, comes with PID (Proportional Integral Derivative) system that constantly checks the temperature of the water and adjusts as necessary, ensuring that the brew head remains at the perfect temperature for extraction.
Most coffee lovers know that the temperature of an espresso machine is vital to brewing a great cup of coffee. The ideal brewing temperature for espresso is between 190 to 196 degrees Fahrenheit. To achieve this, your espresso machine must have a quality thermoblock or thermocoil and the boiler must be sized to the correct size.
Additionally, it is important to preheat your machine, portafilter, and cup before you make an espresso. Beginner espresso makers often make the mistake of not preheating their equipment. This is the reason you should always read the instruction manual before making espresso for the first time.
Grind
A barista espresso machine should provide a variety grind settings for you to have the most control over your final cup of coffee. Some machines include an analog pressure gauge which is cool and can help you gain knowledge about your brewing techniques. It is recommended to maintain the pressure of nine bars throughout the entire brewing process. Although this machine can't reach this mark, it's quite close and will serve you well.
Another nice touch on this machine is its built-in burr grinder. This feature is great for beginners because it eliminates the need for an additional grinder. The stainless steel conical grinder features 18 settings, which range from "coarse to fine."
This grinder isn't as good as a standalone but it can help you get started on the right track to making excellent espresso shots. It's easy to clean, and you can pause it during the grinding process, which helps you avoid creating a mountain of grounds that will spill onto your portafilter on its way to making tamps.
This gorgeous and useful machine will allow you to experience being a barista in your own home. It's an excellent choice for anyone who would like to to revisit 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 challenging thing to master. It's important to find the appropriate balance. Too much can cause mineral deposits to develop in your machine. However, too little will result in an espresso cup that is weaker.
The best espresso water has the lowest alkalinity and hardness level. It is best to use a water filter which does not use chlorine and adds a tiny amount (TDS) of total dissolved substances to add calcium and magnesium. This will create an ideal balance of alkalinity as well as hardness. It will also help avoid the necessity to decalcify your equipment.
Using a high quality filtered water is crucial for your machine's long-term health as well as the taste of the coffee it produces. Based on the usage and hardness of your machine you should make use of a descaling product regularly. The products are available in tab, liquid or powder form at a majority of hardware stores.
The Breville Barista Express, a luxury high-end home espresso machine, is designed to bring the cafe experience to your home. It comes with more advanced features when compared to other beginner machines, and is targeted at coffee enthusiasts who want refine their technique and perfect their art of coffee. The thermocoil heating technology with integrated PID controller, centered on the actively heated group head makes it easy to regulate your brewing temperature. This is a significant advantage over competing entry-level models that require longer "temperature surfing" to achieve an espresso shot that is consistent.
