How to Build a Professional Espresso Machine
This is an excellent choice for cafes and coffee shops that wish to attract customers who are enthralled by espresso and barista abilities. It's the official machine for World Barista Championships, and it displays.
The barista can refill the reservoir of water throughout their shift. The machine also comes with steam wands that cool-touch as well as hot water taps for tea.
Water
A commercial espresso machine needs to make a large amount of espresso-based drinks efficiently. That's why these machines are usually constructed of stainless steel, which is more robust and resistant to scratches and break. Espresso machines made of stainless steel make it easier to keep clean and maintained.
Finally, a high-quality machine will have a separate shut off valve for the water line to prevent the buildup of limescale. This will ensure that any repairs are made to the affected components of the machine and won't affect the rest of your operation.
When selecting your water be sure to test it and treat it appropriately to ensure the best results. You can remineralize the water you distill by adding a few minerals. This can negate it's erosive properties and improve its taste, but it can also damage some machines. This is because the remineralized water will cause the boiler sensor to believe that the machine is fully stocked, but it is not. This can cause the machine to overheat and cause damaged.
Grinder
The grinder is a key element of the success of an espresso machine. The grinder converts a raw, unground coffee bean into a finely ground coffee that can be properly tamped into the filter basket to ensure the best extraction.
Commercial-grade professional espresso machines usually include a built-in grinder that can be programmed to grind for different sizes of drinks, ensuring consistent results each time. Super-automatic machines go a step further and automatize the entire process, from brewing to grinding and dispensing. These machines are frequently praised in Lab tests for their ease to use.
A manual or semi-automatic espresso machine requires more involvement from the barista, however the quality of the end product is often worth it. This model won an award known as the Good Housekeeping Coffee Award in 2022 for its intelligent dosing system that is able to measure and delivers the correct amount of coffee each time. It also features a low pressure pre-infusion for an even extraction, and an milk frother that created rich, thick steamed-milk during our tests.
Temperature
Temperature is an important aspect in espresso. If the temperature of the water is not at a suitable level, it could result in a slower extraction and may even result in bitter cups.
High-end espresso machines have tools that can help you keep the proper temperature of your water. One method to achieve this is to use a PID, which monitors and adjusts the temperature of the water. The other way is by using a double boiler system. You can use one boiler to heat steam and water for tea, and use the second to heat water to brewing temperature.
Carles mentions that these kinds of systems can make a difference for large corporations and baristas at home alike. They can make it easier for newbies to determine the ideal espresso drink since they can keep an exact temperature and eliminate some of the variables that can alter the flavor profile. It's also easier for baristas who have more experience to get their espressos just the way they want.
Pressure
The pressure that an espresso machine utilizes can affect the quality of coffee it produces. Many espresso drinkers have noticed that their drinks have a distinct taste different based on the amount of pressure that is used, even though all other factors are constant.
In general, commercial-grade machines use nine bars of pressure to brew espresso. These machines are also more likely to be steam-driven rather than pumps-driven. While there are higher-pressure machines but they usually require a more complicated group head design that can manage the higher pressure levels.
While some espresso machines advertise 15 or 18 bars of pressure on their machines Nine bars are generally considered to be the gold standard for creating consistently great brews. These machines with higher pressures are generally less expensive and are intended to be used at home.

To put 9 bars of pressure in perspective, it's four times the pressure which is emitted by the air in your car tire. The greater the pressure an espresso maker with professional quality can apply, then the better it will be at capturing the flavor of the coffee beans you love. For espresso machines for home , it's worth investing in a high-end machine that can give you the highest quality results.
Barista Skills
A barista needs to be able take orders and handle them quickly and accurately. This is particularly crucial in busy times in the coffee shop. Being able to provide excellent customer service is also crucial for establishing relationships with customers and generating more business for the shop. This includes acknowledging regular customers, working to resolve issues efficiently and remaining positive and helpful in difficult situations.
Baristas typically need to be adept at multitasking as they are expected to take orders and operate a cash register, communicate orders with coworkers and respond to phone calls all at once. This ability allows orders to be moving quickly to the customer, and ensures that customers have a pleasant experience in the coffee shop.
It is essential for a barista to have knowledge of the various types of drinks that can be prepared using an espresso machine. You can get acquainted with the various types of espresso by reading up on them, experimenting with them in person, or watching online videos. Many baristas find it beneficial to take classes on the topic, which are provided by a variety of organizations.
