It is equipped with a reservoir of water so that the barista only requires refilling it throughout their shift. The machine is equipped with a hot water tap for tea and cool-touch steam wands.

Water

A commercial espresso machine must be able to make a large amount of espresso based drinks in an efficient manner. That's why they are usually constructed of stainless steel which is more robust and resistant to scratches and break. These espresso machines are easier to maintain and keep clean.

A good quality machine should include a separate shut-off valve to the water pipe, to prevent limescale build-up. This will ensure any repairs are only limited to the affected components of the machine and will not interfere with the other operations.

Test your water to ensure it is treated properly. Remineralize water that has been distilled by adding a few minerals. This could reduce its negative erosive properties and enhance the taste, but it may also damage machines. The remineralized wate will make the boiler sensor think the machine is full even though it's not. This can lead to overheating and even damage to the machine.

Grinder

The grinder is a crucial component of a successful espresso maker. The grinder converts the raw, unground coffee bean into a finely -ground coffee that can be tamped properly into the filter basket to ensure an outstanding extraction.

Professional-grade commercial machines include grinders that can be programmed to work with different sizes of drink. This ensures constant results every time. Super-automatic espresso machines go one step further, by automating and programmable the entire process from brewing to dispensing. These machines are often praised during Lab tests for their ease to use.

A semi-automatic or manual espresso machine requires more involvement from the barista but the quality of the final product is often worth it. This model won a 2022 Good Housekeeping Coffee Award for its dosing technology that weighs and distributes the correct amount of ground coffee each time. It also has the ability to use a low pressure pre-infusion to ensure balanced extraction, and an milk frother that created dense, thick steamed milk during our tests.

Temperature

The temperature is a crucial factor in espresso. If the water isn't in its ideal temperature, it can cause a delay in extraction, and could lead to an unpleasant cup of coffee.

High-quality pro espresso machine machines come with devices that allow you to maintain the correct temperature of your water. One method to achieve this is to use a PID, which monitors and adjusts the temperature of the water. Another method is using a double boiler system. This lets you use one boiler for steam and tea and the other one to heat water to brew temperatures.

Carles mentions that these systems can make a difference for large businesses and baristas working at home. They can make it much easier for beginners to get the perfect buy espresso machine shot because they maintain an exact temperature and eliminate some of the variables that can alter the flavor profile. It's also much easier for baristas with more experience to dial in their espressos exactly how they prefer.

Pressure

The pressure an espresso machine makes use of is another element that contributes to the quality of the coffee it makes. Many espresso maker barista drinkers have observed that their drinks taste different depending on the pressure they use, even if all other variables remain the same.

Most commercial machines use 9 bars of pressure in order to make espresso. These machines also tend to be pump-driven, not steam-driven. While higher-pressure machines exist however, they typically require a more sophisticated group head design to handle the increased pressure levels.

While some espresso machines advertise 15 or 18 bars of pressure on their machines nine bars are usually considered to be the gold standard for making consistently excellent espressos. These machines with higher pressure are typically less expensive and are designed for home use.

In comparison, 9 bar of pressure is four times greater than the pressure that is exerted by your car tire. The more pressure a professional espresso maker can apply, the better at capturing the flavor of your favorite coffee beans. It's worth investing in a high-end machine that will deliver the most effective results.

It is essential for a barista to know the various kinds of drinks that can be made using an espresso machine. This can be mastered by reading about the various types of coffee, attempting the drinks in person and watching videos on the internet. Many baristas find it helpful to attend classes provided by various organizations.
