The barista is able to refill the water reservoir throughout their shift. The machine also has steam wands that are cool-touch and hot water taps for tea.
Water
A commercial espresso machine must be able to produce a high volume of espresso based drinks in an efficient manner. This is why these machines are typically built from stainless steel, which is more robust and resistant to scratches and breaks. These espresso machines are easier to maintain and 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 made to the affected components of the machine and won't impact the rest of your operation.
Check your water and ensure it is treated properly. For example, distilled water can be remineralized by adding a small amount of minerals back into it. This can negate it's erosion properties and improve its flavor, but it may also damage machines. This is because the remineralized liquid will cause the boiler sensor to think that the machine is full when it is not. This can lead to overheating and possibly damaging the machine.
Grinder
The grinder is a key component of an espresso machine that is successful. The grinder converts the unground, raw coffee bean into a finely -ground coffee that can be tamped properly into the filter basket to ensure the best extraction.
Commercial-grade professional machines include grinders that can be programmed for different drink sizes. This guarantees the same results every time. Super-automatic machines go one step further and automate the entire process from brewing through grinding and dispensing. These kinds of machines typically get high marks in Lab tests for their hands-off user-friendliness.
Manual or semi-automatic machines require more work from the barista, but the results are worth the effort. This model was awarded the Good Housekeeping Coffee Award in 2022 for its intelligent dosing system that is able to measure and dispenses the right amount of coffee each time. It also has an infusion with low pressure for balanced extraction, and an milk frother that created rich, thick steamed-milk during our tests.
Temperature
When it is about espresso temperature plays a huge factor in the taste and quality of your coffee. If the water isn't at its optimal temperature, it can hinder extraction and even lead to bitter coffee.
High-quality espresso machines come with tools that help you maintain the proper temperature of your water. One way to do this is by utilizing an PID, which monitors and adjusts the temperature of the water. Double boiler systems are a second method to do this. This allows you to make use of one boiler for steam and tea, while the other heats water to brew temperatures.
Carles explains how these systems can make a difference for large corporations as well as baristas working from home. They can assist novices get the perfect espresso because they are able to maintain an exact temperature while avoiding numerous variables that could affect the flavor quality. It helps experienced baristas to create their shots exactly how they would like them.
Pressure
The pressure that an espresso machine utilizes also affects the quality of the coffee it produces. Many espresso drinkers have noticed that their drinks taste different depending on the pressure employed, even when all other elements remain the same.
In general, commercial grade machines utilize nine bars of pressure to make espresso. These machines are also more likely to be steam-driven than pump-driven. While higher-pressure machines are readily available, they require a group head that is more complicated to handle the increased levels of pressure.
While some espresso machines advertise 15 or 18 bars of pressure in their machines, nine bars are generally considered to be the standard for making consistently great espressos. The higher-pressure machines are typically less expensive and are designed for home use.
To put 9 bars of pressure in perspective, it's more than four times the pressure that's exerted by the air inside your car tire. The more pressure an espresso maker that is professional can apply, then the better it is at separating flavor from the coffee beans you love. This is why it's worth investing in a high-quality machine that can deliver the highest quality results.
