Water

A commercial espresso machine must be able to produce a large quantity of espresso-based drinks in an efficient manner. That's why these machines are usually constructed of stainless steel which is more robust and resistant to breaks and scratches. Stainless steel espresso machines also make it easier to keep clean and maintained.

A good machine has a shut-off valve for the water line to avoid the build-up of limescale. This will ensure that any repairs are isolated to the affected parts of the machine and won't impact the rest of your operation.

When you select your water be sure to test it and treat it correctly to ensure the best results. For example, distilled water can be refining by adding a small amount of minerals back into it. It can improve the taste and reduce its erosive qualities, but can also harm 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 cause damaged.

Grinder

The grinder is a vital element in an espresso machine that is successful. It grinds a raw bean and transforms it into finely ground coffee that can then be placed into the filter basket, resulting in an excellent extraction.

Commercial-grade espresso machines usually include a built-in grinder that can be programmed to grind for various drink sizes, ensuring consistency in results every time. Super-automatic espresso machines go one step further, implementing automation and programmable the whole process from brewing to grinding to dispensing.

Fortunately, espresso machines of high-end quality have tools that allow you to ensure that your water is at the correct temperature. A PID monitors and regulates the temperature of the water. Double boiler systems are another method to do this. This allows you to use a single boiler to steam and tea and the other one to heat water to brewing temperatures.

Pressure

The pressure an espresso machine uses also affects the quality of coffee it makes. Many espresso drinkers notice that their coffees taste different based on the amount of pressure they use, even if all other factors remain constant.

In general, most commercial-grade machines utilize nine bars of pressure to create espresso. These machines are also more likely to be steam-driven rather than pump-driven. While higher-pressure machines are readily available however they require a group head that is more sophisticated to handle the higher levels of pressure.

Although you might see espresso machines advertising 15 or even 18 bars of pressure, nine bars is generally regarded as the gold standard for consistently great brews. These machines that are higher pressure tend to be cheaper and are designed for home use.
