How to Build a Professional Espresso Machine

For coffee shops and cafes looking to attract customers with a love of barista and espresso, this is an excellent choice. It's the official machine for the World Barista Championships, and it shows.

It has a water reservoir which means that the barista requires refilling it throughout their shift. The machine also comes with steam wands that are cool-touch and a hot water tap for tea.

Water

A commercial espresso machine is required to produce a high volume of uk espresso machine-based drinks in an efficient manner. The machines are typically made of stainless steel, which is strong and resistant to breaks and scratches. Stainless steel espresso machines also make it easier to keep clean and maintained.

A good machine will have a separate shut-off valve for the water line, to prevent the build-up of limescale. This will ensure that any repairs are confined to the affected parts of the machine and won't affect the rest of your operation.

Check your water and make sure that it has been treated properly. For example, distilled water can be recycled by adding a small amount of minerals back into it. This can reduce its erosive properties and improve the taste, but it could also harm certain machines. This is because the remineralized fluid will cause the boiler sensor to believe that the machine is filled, when it's not. This could cause overheating and even damage to the machine.

Grinder

The grinder is an essential element of a successful espresso machine. It takes a raw, unground bean and transforms it into finely ground coffee that can be properly tamped into the filter basket to create an excellent extraction.

Commercial-grade professional espresso machines typically come with a built-in grinder that can be programmed to grind various sizes of drinks, which ensures the same results every time. Super-automatic espresso machines go one step further, automating and programmable the entire process from brewing to grinding to dispensing. These machines are often praised during Lab tests for being easy to use.

A semi-automatic or manual espresso machine requires more involvement from the barista, but the quality of the final result is often worth the effort. This model won a Good Housekeeping Coffee Award in 2022 for its smart dosing mechanism that measures and dispensing the correct amount of coffee every time. It also has a low pressure pre-infusion for well-balanced extraction, as well as an milk frother that created thick, rich steamed milk in our tests.

Temperature

When it comes to espresso temperature plays a huge role in the taste and quality of your espresso. If the water temperature is not at its ideal level, it can cause extraction to be impeded and even result in an unpleasant cup.

Fortunately, high-quality espresso machines come with tools that enable you to keep your water at the correct temperature. One method to achieve this is by using PIDs that monitor and adjusts the temperature of the water. Another method is utilizing a double boiler system. One boiler can be used to heat steam and water for tea, while using the other to heat water to brewing temperature.

Carles explains how these systems can make a difference for both large-scale businesses as well as home-based baristas. They can make it simpler for beginners to determine the ideal espresso shot because they can maintain an accurate temperature and avoid many of the variables that can alter the flavor profile. It's also easier for baristas who have more experience to dial in their espressos just how they would like.

Pressure

The pressure an espresso machine makes use of is another element that contributes to the quality of the coffee it produces. Many espresso drinkers have noticed that their drinks taste differently based on the pressure used, even if all other elements remain the same.

In general, most commercial-grade machines utilize nine bars of pressure to make espresso. They also tend to be pump-driven instead of steam-driven. While higher-pressure machines exist but they usually require a more complicated group head design to manage the higher pressure levels.

Although you might see espresso machines that advertise 15 or even 18 bars of pressure, nine bars are generally considered the gold standard for making consistently great brews. These higher-pressure machines tend to be cheaper and designed for home use.

In comparison, 9 bar of pressure is 4 times more than the pressure that is exerted by your car tire. The greater pressure a professional espresso machine can put on to the coffee, the better it will be at capturing the flavor of your favorite coffee beans. It's worth investing in top-quality machines that can give the highest quality results.

Barista Skills

A barista should be able to accept and process orders of customers quickly and efficiently. This is particularly important when there is a lot of activity at the coffee shop. Effective customer service skills are crucial to build relationships with customers and boosting the sales of the coffee shop. This includes recognizing regular customers, working to resolve issues efficiently and remaining optimistic and amiable in tough situations.

Having strong multitasking skills is usually required for baristas, since they may be required to take orders and operate the cash register, communicate orders to coworkers and respond to calls at the same time. This ability allows orders to be moving quickly to the customer and allows them to have an enjoyable experience at the coffee shop.

It is helpful for a barista to know the various kinds of drinks that can be made by an espresso machine. You can learn about the various types of espresso by studying about their characteristics, tasting them in person, and watching online videos. Many baristas also find it beneficial to take classes on the topic, which are offered by various organizations.
