How to Build a Professional Espresso Machine

For coffee shops and cafes seeking to attract customers with an interest in espresso and barista abilities, this is a great option. It's the official machine for World Barista Championships, and it demonstrates.

It is equipped with a reservoir of water which means that the barista has to refill it during their shift. The machine comes with an hot water tap for tea and cool-touch steam wands.

Water

A commercial espresso machine has to produce a high volume of espresso-based drinks in an efficient manner. That's why these machines are generally constructed from stainless steel which is more robust and resistant to scratches and breaks. Stainless steel espresso machines also make it easier to clean and maintain.

A high-quality machine must have a separate shut-off valve to the water pipe to avoid the build-up of limescale. This will ensure any repairs are limited to the affected parts of the machine and will not interfere with the other operations.

When choosing your water ensure that you test it and treat it properly to ensure the best bean to cup espresso machine results. You can remineralize the water you distill by adding some minerals. This could reduce its anti-erosive properties as well as improve its flavor, but it may also damage machines. This is because the remineralized fluid will cause the boiler sensor to think that the machine is full when it's not. This could cause overheating and damage the machine.

Grinder

The grinder is a crucial component of a successful espresso maker. It takes a raw, unground bean and transforms it into finely ground coffee that is then tamped into the filter basket to produce an excellent extraction.

Commercial-grade espresso machines usually come with a built-in grinder that can be programmed to grind for different sizes of drinks, which ensures that the results are consistent every time. Super-automatic espresso machines go one step further, implementing automation and programming the entire process from brewing to grinding to dispensing. These machines are often praised in Lab tests for being easy to use.

Semi-automatic or manual machines demand more work from the barista but often the results are worth the effort. This model was awarded a Good Housekeeping Coffee Award in 2022 for its clever dosing system that measures and distributes the right amount of coffee each time. It also features a low pressure pre-infusion for well-balanced extraction, as well as the milk frother produced dense, thick steamed milk during our tests.

Temperature

When it is about espresso temperature, it plays an important impact on the flavor and quality of your coffee. If the water isn't in its optimal temperature, it can affect extraction and can lead to the coffee being bitter.

Luckily, the Best Espresso machine espresso machines have tools that allow you to keep your water at the right temperature. One method to achieve this is by utilizing a PID, which monitors and adjusts the temperature of the water. Another option is utilizing a double boiler system. One boiler can be used to heat steam and water for tea, while using the second boiler for heating water to brewing temperature.

Carles explains that these systems can be beneficial for large corporations as well as home-based baristas. They can make it much easier for newbies to make the perfect espresso shot since they can keep an accurate temperature and avoid some of the variables that can throw off the flavor profile. It also makes it easier for experienced baristas to create their espressos exactly how they would like them.

Pressure

The pressure the espresso machine makes use of also affects the quality of the coffee it makes. Many espresso drinkers have noticed that their drinks taste differently depending on the amount pressure that is used, even though all other factors are constant.

Most commercial machines use 9 bars of pressure to brew espresso. These machines are also more likely to be steam-driven rather than pump-driven. While higher-pressure machines exist they generally require a more complex group head design that can handle the increased pressure levels.

Although you might see espresso machines advertising 15 or even 18 bars of pressure, nine bars are generally considered the gold standard for consistently great brews. These machines with higher pressures are generally cheaper and intended for home use.

To put 9 bars of pressure in perspective, it's more than four times the amount of pressure that's imposed by the air inside your car tire. The greater the pressure that a professional espresso machine is able to apply and the more effective it will be at extracting flavor from your favorite coffee and espresso maker beans. It's worthwhile to invest in high-end machines that produce the highest quality results.

Barista Skills

Baristas often need to be capable of multitasking, as they are required to take orders and operate a cash register and share orders with colleagues and take phone calls all at once. This skill allows the customer to enjoy a pleasant coffee shop experience by ensuring that orders get delivered promptly.

It is beneficial for a barista to be aware of the various styles of drinks that can be prepared with an espresso machine. This can be mastered by reading about the various types of coffee, trying them out in person and watching videos online. Many baristas find it beneficial to take classes offered by various organizations.
