How to Build a Professional Espresso Machine

This is a great option for cafes and coffee shops that wish to attract customers who are enthusiastic about barista and espresso. It's the official machine of the World Barista Championships and it really shows.

The barista is able to refill the water reservoir throughout their shift. The machine comes with an hot water tap for tea and steam wands that cool-touch.

Water

A commercial espresso machine has to create a huge amount of espresso-based drinks in an efficient manner. This is why they are typically built from stainless steel which is more robust and resistant to scratches and break. Stainless steel espresso machines also make it easier to maintain and clean.

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

When choosing your water make sure you test it and treat it appropriately to get the best results. For example, distilled water can be restored by adding a tiny amount of minerals back into it. This can diminish its erosive properties and improve its taste, but it could also cause damage to certain machines. This is because the remineralized water can cause the boiler sensor to think that the machine is filled, when it is not. This could cause the machine to overheat, and eventually be damaged.

Grinder

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

Commercial-grade professional espresso machines typically include a built-in grinder that can be programmed to grind for different sizes of drinks, which ensures consistency in results every time. Super-automatic espresso machine with frother machines take this one step further, automating and programmable the entire process from brewing to grinding to dispensing. These types of machines tend to earn high scores in Lab tests due to their hands-off simplicity of use.

Manual or semi-automatic machines require more work from the barista but often the results are worth it. This model was awarded the 2022 Good Housekeeping Coffee Award for its dosing technology that weighs and dispenses the right amount of ground coffee each time. It also has an low-pressure pre-infusion system for well-balanced extraction, as well as a milk frother that made rich, thick steamed-milk in our tests.

Temperature

When it comes to espresso temperature, it plays an important role in the taste and quality of your coffee. If the temperature of the water is not at its ideal level, espresso machines it can result in the extraction being impeded and may even result in bitter cups.

Fortunately, high-quality espresso machines come with tools that will allow you to ensure that your water is at the right temperature. One method for doing this is by utilizing PIDs, which monitors and adjusts the temperature of the water. Another method is making use of a double boiler. This lets you make use of one boiler for steam and tea and the other one to heat water to brewing temperatures.

Carles explains how these systems can be beneficial for large corporations as well as baristas who work from home. They can make it much easier for newbies to dial in the perfect espresso drink because they maintain an accurate temperature and avoid all the factors that can affect the flavor profile. It's also easier for baristas who have more experience to dial in their espressos just the way they would like.

Pressure

The pressure an espresso machine uses can also impact the quality of coffee it produces. Many espresso drinkers notice that their beverages taste different based on the pressure that is used, even though all other variables remain the same.

In general, commercial grade machines use nine bars of pressure to brew espresso. These machines are also more likely to be steam-driven than pump-driven. Although higher-pressure machines are available, they often require a more sophisticated group head design that can take on the higher pressures.

While you may see some espresso machines advertising 15 or even 18 bars of pressure, nine bars are generally considered the most reliable standard for producing consistently excellent brews. These machines with higher pressure tend to be cheaper and are designed for home use.

To put 9 bars of pressure into perspective, it's nearly four times the amount that's exerted by the air inside your car tire. The more pressure a professional espresso machine can apply to the coffee, the better it will be at capturing the flavor of the coffee beans you love. It's worth investing in top-quality machines that can give the most effective results.

Barista Skills

A barista should be able to accept and process orders from customers quickly and efficiently. This is particularly crucial when there is a lot of activity at the coffee shop. Good customer service skills is also vital to establishing customer relationships and increasing sales for the shop. This includes acknowledging regular customers, working to resolve problems efficiently, and remaining positive and amiable in tough situations.

Having strong multitasking skills is often necessary for a barista as they might be required to take orders and operate the cash register and also communicate orders to their coworkers and answer phone calls simultaneously. This skill allows the customer to enjoy an enjoyable experience at the coffee shop by making sure that orders are delivered quickly.

It is essential for baristas to know the various styles of drinks that can be made with an espresso machine. You can learn about the various kinds of espresso by reading up on them, trying them in person, or watching online videos. Many baristas find it helpful to attend classes offered by various organizations.
