Water

A commercial espresso machine must be able to create a huge amount 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 scratches and breaks. Stainless steel espresso machines also make it easier to keep clean and maintained.

Additionally, a top quality machine will have a separate shut-off valve for the water line to avoid the buildup of limescale. This will ensure that any repairs will be isolated to the affected parts of the machine and won't impact the remainder of your operation.

Test your water and ensure that it has been treated properly. espresso coffee machine can remineralize the water you distill by adding a few minerals. This can negate it's negative erosive properties and enhance the taste, but it can also damage some machines. Remineralized wate makes the boiler sensor think the machine is full, even though it isn't. This could cause the machine to overheat and be damaged.

Grinder

The grinder is a vital component of the success of an espresso machine. It grinds a raw bean and turns it into a finely ground coffee that is then placed into the filter basket to produce an excellent extraction.

Professional espresso machines of commercial grade typically include a built-in grinder that can be programmed to grind different sizes of drinks, which ensures consistency in results every time. Super-automatic machines go a step further and automate the entire process from brewing through grinding and dispensing. These types of machines are able to score high scores in Lab tests due to their hands-free user-friendliness.

Semi-automatic or manual machines demand more effort from the barista but often the results are worth it. This model won a Good Housekeeping Coffee Award in 2022 for its clever dosing system that measures and dispenses the right amount of coffee every time.

They can make it easier for newbies to dial in the perfect espresso because they can maintain an accurate temperature and avoid some of the factors that can alter the flavor profile. It helps experienced baristas to make their shots exactly as they want them.

Pressure

The pressure an espresso machine utilizes can also impact the quality of the coffee it makes. Many espresso drinkers notice that their drinks taste different depending on the amount of pressure employed, even when all other elements remain the same.

In general, commercial grade machines use nine bars of pressure to make espresso. These machines are also more likely to be steam-driven than pumps driven. Although higher-pressure machines are available but they usually require a more complex group head design that can handle the increased pressure levels.

While some espresso machines advertise 15 or 18 bars of pressure in their machines nine bars are usually considered to be the gold standard when it comes to making consistently great espressos. These machines with higher pressure tend to be less expensive and designed for use at home.

In comparison, 9 bar of pressure is four times more than the pressure that is exerted by your car tire. The more pressure a professional espresso machine can exert to the coffee, the better it will be at capturing the flavor of the coffee beans you love. For this reason, it's worth investing in a high-quality machine that can deliver the best results.

Baristas often need to be capable of multitasking, as they are required to take orders, operate a cash register and communicate orders with coworkers, and answer telephone calls all at once. This skill allows the customer to enjoy an enjoyable coffee shop experience by ensuring that orders are served quickly.

It is helpful for baristas to be aware of the various types of drinks that can be prepared with an espresso machine.
