How to Build a Professional Espresso Machine
This is a great choice for cafes and coffee shops which want to draw customers who are passionate about barista and espresso skills. It's the official machine used for World Barista Championships and it really shows.
The barista is able to refill the reservoir of water throughout their shift. It also has steam wands that are cool-touch and a hot water tap for tea.
Water
A commercial espresso machine is required to make a large amount of espresso based drinks efficiently. This is why these machines are built with stainless steel which is more durable and resistant to scratches and break. Espresso machines are also simpler to maintain and clean.
A top-quality machine should have an independent shut-off valve for the water pipe to prevent limescale accumulation. This will ensure that any repairs are restricted to the affected components of the machine and won't impact the rest your operation.
Check your water and ensure it's being treated correctly. For instance, distilled water can be recycled by adding a small amount of minerals back into it. It can improve the taste and negate its erosive properties, however it can also harm certain machines. Remineralized wate makes the boiler sensor believe that the machine is full, even though it isn't. This can cause excessive heat and damage to the machine.
Grinder
The grinder is a crucial element in an espresso machine that works. It grinds a raw bean and transforms it into finely ground coffee that can be properly placed into the filter basket to create an excellent extraction.
Professional espresso machines of commercial grade typically come with a built-in grinder that can be programmed to grind various sizes of drinks, providing the same results every time. Super-automatic machines go one step further and automate the entire process from brewing to grinding and dispensing. These machines are often praised during Lab tests for their ease to use.
Semi-automatic or manual machines require more work from the barista but often the results are worth the effort. This model was awarded an award called the Good Housekeeping Coffee Award in 2022 for its clever dosing system that measures and dispenses the right amount of coffee each time. It also has an infusion with low pressure for an even extraction, and a milk frother that produced rich, thick steamed-milk in our tests.
Temperature
Temperature is an important element in espresso. If the water isn't at an ideal temperature, it may cause a delay in extraction, and could lead to bitter coffee.
Fortunately, espresso machines of high-end quality come with tools that will allow you to ensure that your water is at the right temperature. One method of doing this is with PIDs that monitor and adjusts the temperature of the water. Double boiler systems are another method to do this. This allows you to use one boiler for tea and steam and the other one to heat water to brewing temperatures.
Carles states that these types of systems can make a difference for large companies and baristas working at home. They can make it simpler for newbies to get the perfect espresso drink because they maintain an exact temperature and eliminate a lot of the factors that can alter the flavor profile. It's also much easier for baristas with more experience to dial in their espressos just the way they would like.
Pressure
The pressure that an espresso machine is using can also impact 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 used, despite the fact that all other elements remain the same.
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 higher-pressure machines exist however, they typically require a more sophisticated group head design that can manage the higher pressure levels.
Although you might see espresso machines advertising 15 or even 18 bars of pressure, nine bars are generally considered to be the gold standard for creating consistently great brews. These machines that are higher pressure are generally cheaper and intended to be used at home.
To put 9 bars of pressure in perspective, it's more than four times the pressure that's imposed by the air in your car tire. The more pressure a professional espresso machine can apply to the coffee, the better it will be at extracting flavor from the coffee beans you love. It's worth investing in a high-end machine that will deliver the highest quality results.

Baristas are often adept at multitasking as they are required to take orders and operate a cash counter and share orders with colleagues and handle phone calls all at once. This ability allows customers to enjoy an enjoyable experience at the coffee shop by ensuring that orders get delivered quickly.
