For coffee shops and cafes looking to attract customers with passion for barista and espresso skills, this is an excellent choice. It's the official machine for World Barista Championships and it really does show.
The barista is able to refill the reservoir with water throughout their shift. The machine also has steam wands with cool-touch technology and a hot water tap for tea.
Water
A commercial espresso machine has to be able to make an enormous amount of espresso-based drinks in a timely manner. They are typically made of stainless steel, which is durable and resistant against cracks and scratches. Espresso machines made of stainless steel make it easier to clean and maintain.
A good machine has a shut off valve for the water line to avoid the build-up of limescale. This will ensure that any repairs will be isolated to the affected parts of the machine and won't impact the remainder of your operation.
Check your water and make sure it is treated properly. For example distilled water may be recycled by adding a small amount of minerals back into it. It can improve the taste and reduce its erosive characteristics, but can also harm certain machines. This is because the remineralized water will cause the boiler sensor to believe that the machine is full when it's not. This could cause overheating and possibly damaging the machine.
Grinder
The grinder is an essential element of a successful espresso maker. It grinds a raw bean and turns it into finely ground coffee that can be properly placed into the filter basket to produce an excellent extraction.
professional espresso machine for home-grade commercial machines include grinders that are programmed to accommodate different sizes of drinks. This guarantees the same results every time. Super-automatic espresso machines go one step further, by automating and programmable the whole process from brewing to grinding to dispensing. These kinds of machines usually get high marks in Lab tests for their hands-off user-friendliness.
A manual or semi-automatic espresso machine requires more involvement by the barista, but the quality of the end result is often worth the effort. This model was awarded the 2022 Good Housekeeping Coffee Award for its intelligent dosing system that weighs and dispenses the correct amount of ground coffee every time. It also includes a low-pressure pre-infusion mechanism for balanced extraction and the milk frothing wand, which performed well in our tests for producing thick, rich steaming milk.
Temperature
When it is about espresso, temperature plays a major factor in the taste and quality of your shots. If the water isn't operating at an optimal temperature, it could cause a delay in extraction, and could result in an unpleasant cup of coffee.
Luckily, the best espresso machines include tools that allow you to keep your water at the correct temperature. A PID monitors and regulates the temperature of the water. Double boiler systems are a second method to do this. You can use one boiler to heat water and steam for tea, while using another to heat the water to brewing temperature.
Carles explains that these systems can be beneficial for large companies as well as baristas at home. They can assist novices dial in the perfect espresso drink because they are able to maintain the exact temperature and prevent many variables that can affect the flavor profile. It helps experienced baristas to get their espressos exactly how they would like them.
Pressure
The pressure an espresso machine makes use of is another element that influences the quality of the coffee it produces. Many espresso drinkers notice that their beverages taste different based on the amount of pressure they use, even if all other factors remain the same.
Most commercial machines use 9 bars of pressure to make espresso. These machines are also likely to be driven by pumps rather than steam-driven. While higher-pressure machines exist but they usually require a more complicated group head design that can take on the higher pressures.
While you may see espresso machines that advertise 15 or even 18 bars of pressure, nine bars are generally considered the gold standard for creating consistently excellent brews. These machines with higher pressure tend to be less expensive and are designed for home use.
To put 9 bar of pressure in perspective, it's nearly four times the amount of pressure which is emitted by the air in your car tire. The greater the pressure a
professional espresso maker can apply, then the more effective it is at extracting flavor out of your favorite coffee beans. This is why it's worth investing in a high-quality machine that will deliver the highest quality results.
Barista Skills
Baristas must be able to take and process orders from customers quickly and accurately. This is especially important in busy times at the coffee shop.

Baristas are often capable of multitasking, as they are required to take orders and operate a cash counter and share orders with colleagues and take phone calls at the same time. This ability helps keep orders moving quickly to the customer and will allow them to have an enjoyable time in the coffee shop.
It is essential for a barista to have knowledge of the various styles of drinks that can be prepared using an espresso machine. This can be mastered by reading about the various types of coffee, attempting them out in person and watching videos online. Baristas often find it beneficial to attend classes on the subject, which are offered by several organizations.
