Water
A commercial espresso machine has to produce a large quantity of espresso-based drinks efficiently. That's why they are built with stainless steel, which is more robust and resistant to breakage and scratches. Stainless steel espresso machines also make it easier to clean and maintain.
A good quality machine should have a separate shut-off valve for the water pipe to avoid the accumulation of limescale. This will ensure any repairs are limited to the affected components of the machine and will not affect the operation of the rest.
When selecting the water you want to drink, make sure to test it thoroughly and treat it in a way to get the best results. Remineralize water that has been distilled by adding some minerals. It can enhance the taste and reduce its erosive properties, however it can also damage certain machines. The remineralized wate will make the boiler sensor think that the machine is full however it's not. This could cause overheating and possibly damaging the machine.
Grinder
The grinder is an essential part of a successful espresso maker. The grinder transforms a raw, unground coffee bean into finely-ground coffee that can be properly tamped into the filter basket to ensure an excellent extraction.
Commercial-grade professional espresso machines usually include a built-in grinder that can be programmed to grind for various drink sizes, ensuring consistent results each time. Super-automatic espresso machines go one step further by automating and programmable the entire process from brewing to grinding to dispensing. These types of machines usually get high marks in Lab tests due to their hands-free simplicity of use.

This model won an award known as the Good Housekeeping Coffee Award in 2022 for its smart dosing mechanism that measures and delivers the correct amount of coffee each time. It also comes with a low-pressure pre-infusion system to ensure an even extraction, as well as the milk frothing wand, which was a success in our test for producing thick, rich steamed milk.
Temperature
The temperature is a crucial factor in espresso. If the water isn't in its ideal temperature, it can affect extraction and can result in bitter coffee.
Espresso machines of the highest quality come with devices that allow you to maintain the right temperature of your water. A PID monitors and regulates temperature of the water. best home espresso machine are another way to accomplish this. One boiler can be used to heat water and steam for tea, while using the second boiler to heat the water to brewing temperature.
Carles points out that these types of systems can make a big difference for large-scale businesses and baristas at home alike.

It is also simpler for baristas with more experience to make their shots just the way they want.
Pressure
The amount of pressure an espresso machine employs is another factor which affects the quality of the coffee it makes. Many espresso drinkers notice that their drinks taste different based on the pressure that is used, even though all other factors remain the same.
The majority of commercial machines utilize 9 bars of pressure to make espresso. They also tend to be driven by pumps rather than steam-driven. While there are higher-pressure machines but they usually require a more sophisticated group head design that can handle the higher pressure levels.
While you may see some espresso machines advertising 15 or even 18 bars of pressure, nine bars are generally regarded as the gold standard for making consistently excellent espressos. These machines with higher pressure tend to be more affordable and designed for home use.
To put 9 bar of pressure in perspective, it's over four times the amount that's imposed by the air in your car tire. The more pressure that an espresso maker with professional quality can apply, the better it is at separating flavor from the coffee beans you love. For this reason, it's worthwhile to invest in a top-quality machine that will deliver the most effective results.
