Water
A commercial espresso machine has to be able to produce an enormous amount of espresso-based drinks effectively. They are usually constructed of stainless steel, which is durable and resistant against scratches and breaks. Stainless steel espresso machines also make it easier to keep clean and maintained.
A high-quality machine must have an independent shut-off valve for the water pipe to prevent limescale build-up. This will ensure that any repairs are made to the specific machine components and won't affect the rest of your operation.
Check your water and make sure it is treated properly. You can remineralize distilled water by adding a few minerals. This can diminish its erosion properties and improve its taste, however it could also cause damage to 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 can cause the machine to overheat, and eventually be damaged.
Grinder
The grinder is a vital component of the success of an espresso machine. The grinder transforms the raw, unground coffee bean into a finely-ground coffee which can be tamped correctly into the filter basket to ensure an outstanding extraction.
Professional commercial machines come with grinders that can be programmed to accommodate different sizes of drinks. This guarantees consistent results every time. Super-automatic machines go further and automate the entire process from brewing through grinding and dispensing. These machines are frequently praised in Lab tests for being easy to use.

This model won an award called the Good Housekeeping Coffee Award in 2022 for its intelligent dosing system, which measures and dispensing the correct amount of coffee every time. It also comes with a low pressure pre-infusion system to ensure smooth extraction and the milk frothing tool that performed well in our tests for producing rich, thick steamed milk.
Temperature
Temperature is an important aspect in espresso. If the temperature of your water is not at a suitable level, it could result in a slower extraction and can even lead to a bitter cup.
High-quality espresso machines come with devices that allow you to maintain the proper temperature of your water. One method for doing this is to use a PID, which monitors and adjusts the temperature of the water. Double boiler systems are another way to do this. One boiler can be used to heat steam and water for tea, and use the second boiler to heat water to the brewing temperature.

They can assist novices dial in the perfect espresso shot because they can maintain a precise temperature and avoid numerous variables that could affect the flavor quality. It's also easier for baristas who have more experience to make their espressos just how they want.
Pressure
The pressure that an espresso machine utilizes also affects the quality of coffee it makes. Many espresso drinkers have noticed that their drinks 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 make espresso. These machines are also more likely to be steam-driven rather than pump-driven. Although high-pressure machines are offered however, they require a group head that is more intricate to handle the higher levels of pressure.
While you may see espresso machines advertising 15 or even 18 bars of pressure, nine bars is generally regarded as the gold standard for making consistently excellent espressos. These machines with higher pressures are generally smaller and designed to be used at home.
To put 9 bar of pressure into 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, the better it will be in bringing out the flavor of your favorite coffee beans. This is why it's worth investing in a high-end machine that can deliver the most effective results.
