How to Build a professional espresso machine (you could check here)

For cafes and coffee shops looking to attract customers with passion for espresso and barista skills this is a great choice. It's the official machine for World Barista Championships and it really shows.

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

Water

A commercial espresso machine has to be able to produce large quantities of espresso-based drinks with efficiency. That's why they are usually constructed of stainless steel which is more robust and resistant to scratches and breaks. Espresso machines made of stainless steel make it easier to clean and maintain.

A top-quality machine should have a separate shut-off valve to the water pipe to avoid limescale build-up. This will ensure that any repairs are made to the specific machine components and won't impact the rest of your operation.

When selecting your water make sure you test it and treat it correctly to ensure the best results. For example distillate water can be remineralized by adding a small amount of minerals back to it. This can negate it's erosion properties and improve its flavor, but it could also cause damage to certain machines. The remineralized water will make the boiler sensor think the machine espresso is full and it isn't. This can lead to overheating and possibly damaging the machine.

Grinder

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

Professional commercial grade machines include grinders that can be programmed for various sizes of drinks. This ensures the same results every time. Super-automatic espresso machines take this one step further, by automating and programmable the entire process from brewing to dispensing. These types of machines typically get high marks in Lab tests for their hands-off simplicity of use.

Semi-automatic and manual machines require more work from the barista, but the results are worth it. This model earned a 2022 Good Housekeeping Coffee Award for its smart dosing feature that weighs and distributes the correct amount of ground coffee each time. It also has the ability to use a low pressure pre-infusion to ensure well-balanced extraction, as well as a milk frother that produced dense, thick steamed milk during our tests.

Temperature

Temperature is a major Professional Espresso Machine aspect in espresso makers. If the water temperature is not at its ideal level, it may result in a slower extraction and even result in bitter cups.

Luckily, the best espresso coffee maker machines include tools that allow you to keep your water at the right temperature. A PID monitors and regulates temperature of the water. Double boiler systems are another way to accomplish this. This allows you to use one boiler for tea and steam and the other for heating water to the right temperature for brewing.

Carles explains how these systems can be beneficial for large companies as well as baristas working from home. They can assist novices create the perfect espresso drink because they are able to maintain the exact temperature and prevent many variables that can affect the flavor profile. It's also easier for baristas who have more experience to get their shots just the way they prefer.

Pressure

The pressure an espresso machine uses also affects the quality of the coffee it makes. Many espresso drinkers notice that their coffees taste different based on the pressure they use, even if all other elements remain the same.

In general, commercial-grade machines utilize nine bars of pressure to create espresso. These machines are also likely to be pump-driven, not steam-driven. Although there are machines with higher pressures they generally require a more complicated group head design that can take on the higher pressures.

While you may see espresso machines advertising 15 or even 18 bars of pressure, nine bars are generally considered to be the gold standard for making consistently excellent espressos. These machines with higher pressures are generally more affordable and are designed for use at home.

In comparison, 9 bar of pressure is four times higher than the pressure applied by your car tire. The more pressure a professional espresso machine is able to apply to the coffee, the better it will be at capturing the taste of the coffee beans you love. It is worth investing in top-quality machines that will give you the best results.

Barista Skills

A barista should be able to take orders and process them quickly and precisely. This is particularly crucial during busy times at the coffee shop. Being able to provide excellent customer service is essential to build relationships with customers and generating more business for the shop. This includes recognizing frequent customers, working efficiently to resolve issues, and remaining friendly and positive in challenging circumstances.

Being able to multitask is a must for baristas, since they might be required to take orders and operate the cash register and then communicate orders to coworkers and respond to phone calls at one time. This skill allows them to keep orders moving quickly to the customer, and will allow them to have an enjoyable time in the coffee shop.

It is beneficial for baristas to have knowledge of the various styles of drinks that can be prepared using an espresso machine. This can be accomplished by reading up on the different kinds of coffee, testing them out in person, or watching videos on the internet. Many baristas also find it beneficial to take classes on the topic, which are offered by various organizations.
