How to Build a Professional Espresso Machine
For coffee shops and cafes looking to attract customers with passion for barista and espresso skills, This is a great option. It's the official barista machine for World Barista Championships and it truly shows.
The barista is able to refill the water reservoir throughout their shift. The machine comes with hot water for tea and steam wands with cool-touch.
Water
A commercial espresso machine has to be able to make an enormous amount of espresso-based drinks efficiently. This is why they are typically built from stainless steel, which is more robust and resistant to scratches and break. Stainless steel espresso machines also make it easier to clean and maintain.
A top-quality machine should include a separate shut-off valve to the water pipe in order to prevent limescale build-up. This will ensure that any repairs are limited to affected parts of the machine and will not affect the operation of the rest.
When choosing your water, make sure to test it and treat it correctly to get the best results. For example distillate water can be remineralized by adding a small amount of minerals back to it. It can enhance the taste and negate its erosive properties, however it can also harm certain machines. This is because the remineralized liquid will cause the boiler sensor to believe that the machine is full, even though it's not. This can cause overheating and possibly damaging the machine.
Grinder
The grinder is an essential element for an espresso machine that is successful. The grinder turns an unground, raw coffee bean into a finely-ground coffee that can be tamped properly into the filter basket for an outstanding extraction.
Commercial-grade espresso machines usually have a built-in grinder which can be programmed to grind different sizes of drinks, ensuring consistent results each time. Super-automatic machines go one step further and automate the entire process, from brewing to grinding and dispensing. These machines are often praised by Lab tests for being easy to use.
Manual or semi-automatic machines require more effort from the barista but often the results are worth it. This model was awarded the 2022 Good Housekeeping Coffee Award for its smart dosing feature which weighs and delivers the right amount of ground coffee each time. It also features an low-pressure pre-infusion system for an even extraction, and a milk frother that made rich, thick steamed-milk during our tests.
Temperature
When it is time to make espresso temperature plays a huge influence on the taste and quality of your coffee. If the temperature of the water is not at a suitable degree, it can cause extraction to be hindered and may even result in an unpleasant cup.
High-end espresso machines have tools to help you maintain the right temperature of your water. One way to do this is to use PIDs that monitor and adjusts the temperature of the water. Double boiler systems are another method to do this. You can use one boiler to heat water and steam for tea, while using another to heat water to brewing temperature.
Carles states that these kinds of systems can make a difference for large businesses and baristas working at home. They can assist novices to dial in the perfect espresso shot because they can keep the exact temperature and prevent several variables that can affect the flavor quality. It also makes it easier for baristas with experience to get their shots exactly how they would like them.
Pressure
The pressure an espresso machine utilizes can also impact the quality of the coffee it produces. Many espresso drinkers notice that their beverages taste different based on the amount of pressure employed, even when all other variables remain the same.
Most commercial machines use 9 bars of pressure in order to make espresso. These machines tend to be pump-driven, not steam-driven. Although there are machines with higher pressures but they usually require a more sophisticated group head design to manage the higher pressure levels.
While some espresso machines advertise 15 or 18 bars of pressure in their machines, nine bars are generally considered to be the standard when it comes to making consistently excellent brews. These higher-pressure machines tend to be more affordable and designed for use at home.
In comparison, 9 bars of pressure is four times greater than the pressure exerted by your car tire. The greater the pressure that a professional espresso machine can exert, the better it will be at capturing the flavor of your favorite coffee beans. For this reason, it's worthwhile to invest in a top-quality machine that will deliver the most effective results.
Barista Skills
A barista needs to be able take orders and process them quickly and accurately. This is especially crucial when there is a lot of activity at the coffee shop. Being able to provide excellent customer service is also vital to establishing relationships with customers and generating more business for the shop.

Being able to multitask is often necessary for baristas, since they could be required to take orders, operate the cash register, communicate orders to coworkers and take phone calls at the same time. This ability allows customers to enjoy a pleasant coffee shop experience by ensuring that orders are served promptly.
It is essential for baristas to be aware of the various styles of drinks that can be prepared with an espresso machine. Learn about the different types of espresso by studying about their characteristics, tasting them in person and watching online videos. Many baristas find it beneficial to take classes on the subject, which are offered by several organizations.
