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 barista machine for World Barista Championships and it truly shows.

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

Water

A commercial espresso machine needs to create a huge amount of espresso based drinks in an efficient manner. They are typically made of stainless steel, which is durable and resistant to breakages and scratches. Espresso machines made of stainless steel make it easier to keep clean and maintained.

Finally, a high-quality machine will have a separate shut-off valve for the water line in order to prevent the buildup of limescale. This will ensure that any repairs are only limited to the affected parts of the machine and won't interfere with the other operations.

When selecting your water be sure to test it and treat it properly to ensure the best results. Remineralize espresso coffee machines that has been distilled by adding a few minerals. This can negate it's erosive properties and improve its flavor, but it could also harm certain machines. Remineralized wate makes the boiler sensor think that the machine is full however it's not. This can cause excessive heat and damage to the machine.

Grinder

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

Professional espresso machines of commercial grade typically have a built-in grinding unit that can be programmed to grind different drink sizes, ensuring the same results every time. Super-automatic machines go further and automate the entire process from brewing to grinding and dispensing. These types of machines tend to earn high scores in Lab tests due to their hands-free simplicity of use.

A manual or semi-automatic espresso machine requires more involvement from the barista but the quality of the final result is often worth it. This model won a 2022 Good Housekeeping Coffee Award for its dosing technology that weighs and dispenses the correct amount of ground coffee each time. It also features an low-pressure pre-infusion system for an even extraction, and the milk frother produced rich, thick steamed-milk during our tests.

Temperature

When it comes to espresso temperature, it plays an important impact on the flavor and quality of your coffee. If the temperature of your water is not at a suitable degree, it can cause extraction to be hindered and could result in bitter cups.

Fortunately, top-quality espresso machines have tools that allow you to keep your water at the right temperature. One method for doing this is by utilizing an PID, which monitors and adjusts the temperature of the water. Double boiler systems are another way to do this. This allows you to use one boiler for tea and steam and the other one to heat water to brew temperatures.





Carles says that these systems can make a difference for large corporations and baristas working at home. They can aid novices to dial in the perfect espresso drink because they can maintain the exact temperature and prevent many variables that can affect the flavor profile. It is also easier for baristas who have more experience to make their shots just the way they want.

Pressure

The pressure the espresso machine makes use of can affect the quality of the coffee it produces. Many espresso drinkers have noticed that their coffee tastes differently depending on the amount pressure used, even if other factors remain constant.

In general, commercial-grade machines utilize nine bars of pressure to brew espresso. These machines are also more likely to be steam-driven instead of pumps driven. While higher-pressure machines are readily available however they require a group head that is more sophisticated to handle the higher levels of pressure.

While you may see some espresso machines that advertise 15 or even 18 bars of pressure, nine bars are generally considered to be the gold standard for consistently great brews. These higher-pressure machines are typically smaller and designed for home use.

To put 9 bar of pressure in perspective, it's over four times the amount which is emitted by the air inside your car tire. The more pressure a professional espresso maker is able to apply, the better it will be in bringing out the flavor of your favorite coffee beans. It's worth investing in a high-end machine that will give you the best possible results.

Barista Skills

A barista must be able to take orders and process them quickly and precisely. This is particularly crucial when there is a lot of activity in the coffee shop. Effective customer service skills are also important for building relationships with customers and increasing sales for the coffee shop. This can include recognizing regular customers, working efficiently to resolve issues, and being positive and helpful even in difficult situations.

Baristas frequently need to be capable of multitasking, as they must take orders and operate a cash register and communicate orders with coworkers and respond to phone calls all at once. This skill allows them to keep orders moving quickly to the customer and will allow them to have an enjoyable experience at the coffee shop.

It is beneficial for baristas to have knowledge of the different styles of drinks that can be made with an espresso machine. This can be accomplished by studying the various kinds of coffee, testing the drinks in person and watching videos on the internet. Many baristas find it helpful to attend classes offered by various organizations.
