How to Build a professional espresso machine (Webcastlist's website)

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

The barista can refill the water reservoir throughout their shift. It also has steam wands that cool-touch as well as hot water taps for tea.

Water

A commercial espresso machine coffee machine has to produce a large quantity of espresso based drinks in an efficient manner. That's why these machines are built with stainless steel which is more robust and resistant to breakage and scratches. Espresso machines made of stainless steel make it easier to maintain and clean.

Lastly, a good quality machine has a shut off valve for the water line to prevent the buildup of limescale. This will ensure that any repairs are isolated to the affected machine components and won't affect the rest of your operation.

Check your water to ensure it is treated properly. For instance distillate water can be refining by adding a small amount of minerals back to it. It can enhance the taste and negate its erosive characteristics, but could also cause damage to certain machines. The remineralized wate can make the boiler sensor think that the machine is full however it's not. This could cause the machine to overheat, and eventually be damaged.

Grinder

The grinder is an essential element of a successful pro espresso machine maker. It is used to take a raw, unground bean to cup espresso machines and transforms it into finely ground coffee that can be properly placed into the filter basket to produce an excellent extraction.

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

Manual or semi-automatic machines require more effort from the barista but often the results are worth it. This model was awarded an award known as the Good Housekeeping Coffee Award in 2022 due to its sophisticated dosing mechanism that measures and delivers the correct amount of coffee each time. It also has an low-pressure pre-infusion system for an even extraction, and an milk frother that created rich, thick steamed-milk during our tests.

Temperature

Temperature is a major aspect in espresso. If the water isn't operating at an ideal temperature, it may slow the extraction process and result in the coffee being bitter.

High-quality espresso machines come with tools that help you maintain the right temperature of your water. One method to achieve this is by using a PID, which monitors and adjusts the temperature of the water. Double boiler systems are another method to do this. This allows you to use one boiler for steam and tea while the second one heats water to brewing temperatures.

Carles mentions that these systems can make a big difference for large corporations as well as home baristas. They can make it much easier for newbies to determine the ideal espresso since they can keep an exact temperature and eliminate all the variables that can alter the flavor profile. It's also much easier for baristas with more experience to make their espressos exactly how they want.

Pressure

The pressure an espresso machine uses is another aspect that contributes to the quality of the coffee it makes. Many cafe espresso machine drinkers have observed that their drinks taste differently depending on the amount pressure that is used, even though all other factors are constant.

The majority of commercial machines utilize 9 bars of pressure to brew espresso. These machines are also likely to be driven by pumps rather than steam-driven. Although high-pressure machines are offered but they require a group head that is more complicated to handle the higher levels of pressure.

Although you might see espresso machines advertising 15 or even 18 bars of pressure, nine bars are generally regarded as the most reliable standard for producing consistently great brews. These machines with higher pressures are generally less expensive and are intended for use at home.

To put 9 bar of pressure into perspective, it's over four times the amount of pressure that's imposed by the air in your car tire. The more pressure an experienced espresso machine can apply more pressure, the better it'll be at extracting flavor from your favorite coffee beans. It's worthwhile to invest in high-end machines that will give you the most effective results.

Barista Skills

A barista needs to be able take orders and handle them quickly and precisely. This is especially crucial during busy times in the coffee shop. A good understanding of customer service is essential to build relationships with customers and increasing sales for the shop. This could include recognizing regular customers, working to resolve issues efficiently and remaining positive and welcoming even in stressful situations.

Baristas frequently need to be adept at multitasking as they have to take orders, operate a cash register, communicate orders with coworkers and handle phone calls at the same time. This ability helps keep orders moving quickly to the customer and ensures that customers have an enjoyable experience in the coffee shop.

It is important for a barista's education to be able to make different types of drinks using an espresso machine. This can be learned by studying the various kinds of coffees, trying them in person, and watching videos on the internet. Many baristas also consider it beneficial to attend classes on the topic, which are provided by several organizations.
