These machines are usually made of stainless steel, which is durable and resistant against cracks and scratches. These espresso machines are also easier to maintain and keep clean. Finally, a high-quality machine has a shut-off valve for the water line to avoid the build-up of limescale. This will ensure that any repairs are confined to the specific machine components and won't affect the rest of your operation. Test your water and make sure it is treated properly. For example, distilled water can be recycled by adding a small amount of minerals back into it. It can enhance the taste and lessen its erosive properties, but can also harm certain machines. The remineralized wate can make the boiler sensor think the machine is full and it isn't. This can cause the machine to overheat, and eventually be damaged. Grinder The grinder is a crucial component of an espresso machine that is successful. The grinder transforms the unground, raw coffee bean into a finely ground coffee that can be tamped properly into the filter basket for an outstanding extraction. Commercial-grade professional espresso machines typically have a built-in grinding unit that can be programmed to grind for different sizes of drinks, which ensures that the results are consistent every time.

While some espresso machines advertise 15 or 18 bars of pressure in their machines, nine bars are generally considered to be the gold standard when it comes to making consistently great espressos. These higher-pressure machines are typically cheaper and intended to be used at home. To put 9 bar of pressure into perspective, it's over four times the amount that is exerted by the air inside your car tire.
