How to Build a Professional Espresso Machine

For coffee shops and cafes seeking to attract customers with an interest in barista and espresso, this is a great choice. It's the official machine used for World Barista Championships and it really shows.

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

Water

A commercial espresso machine is required to create a huge amount of espresso based drinks efficiently. This is why they are generally constructed from stainless steel, which is more robust and resistant to scratches and break. Stainless steel espresso machines also make it easier to keep clean and maintained.

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

When selecting your water make sure you test it and treat it properly to get the best results. For example, distilled water can be refining by adding a small amount of minerals back to it. This can reduce its erosive properties and improve the taste, but it may also damage machines. This is because the remineralized liquid will cause the boiler sensor to think that the machine is full, even though it's not. This could cause overheating and possibly damaging the machine.

Grinder

The grinder is a crucial element in an espresso machine that works. It takes a raw, unground bean and transforms it into finely ground coffee that can then be tamped into the filter basket for an excellent extraction.

Commercial-grade espresso machines usually include a built-in grinder that can be programmed to grind different sizes of drinks, ensuring consistent results each time. Super-automatic machines go a step further and automatize the entire process, from brewing to grinding and dispensing. These kinds of machines are able to score high scores in Lab tests due to their hands-free accessibility.

Manual or semi-automatic machines require more effort from the barista but often the results are worth the effort. This model won a 2022 Good Housekeeping Coffee Award for its clever dosing feature that weighs and dispensing the right amount of ground coffee each time. It also has the ability to use a low pressure pre-infusion to ensure an even extraction, and an milk frother that created rich, thick steamed-milk in our tests.

Temperature

When it comes to espresso temperature, it plays an important factor in the taste and quality of your coffee. If the temperature of your water is not at a suitable level, it could result in the extraction being impeded and even result in a bitter cup.

Fortunately, top-quality espresso machines include tools that allow you to ensure that your water is at the right temperature. One method of doing this is with PIDs, which monitors and adjusts the temperature of the water. Double boiler systems are a second method to do this. One boiler can be used to heat steam and water for tea, and use the second to heat water to the brewing temperature.

Carles explains how these systems can be beneficial for both large-scale businesses as well as baristas working from home. They can help novices create the perfect espresso drink because they can maintain an exact temperature and eliminate various variables that can alter the flavor quality. It helps experienced baristas to create their shots exactly as they would like them.

Pressure

The pressure an espresso maker makes use of is another element that contributes to the quality of the coffee it produces. Many espresso drinkers have observed that their drinks taste differently depending on the amount pressure they use, even if other factors remain constant.

Most commercial machines use 9 bars of pressure to make espresso. These machines are also more likely to be steam-driven instead of pumps driven. Although higher-pressure machines are also available but they require a group head that is more intricate to handle the increased levels of pressure.

While you may see some espresso machines that advertise 15 or even 18 bars of pressure, nine bars are generally considered the gold standard for creating consistently great brews. These machines with higher pressures are generally cheaper and intended to be used at home.

In comparison, 9 bar of pressure is four times greater than the pressure applied by your car tire. The greater pressure a professional espresso maker is able to apply, then the better at extracting flavor out of your favorite coffee beans. This is why it's worth investing in a premium machine that can give you the best results.

Barista Skills

A barista must be able to take orders and process them quickly and accurately. This is especially crucial when there is a lot of activity 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 acknowledging regular customers, working to resolve issues efficiently and remaining positive and friendly even in challenging situations.

A strong ability to multitask is a must for baristas, since they may be required to take orders, operate the cash register and then communicate orders to coworkers and take phone calls at the same time. This ability helps keep orders moving quickly to the customer, and coffeee shops will allow them to have a pleasant experience in the coffee shop.

It is crucial for a barista's knowledge in order to make different types of drinks using an espresso machine. You can find out about the different types of coffeee of espresso by reading up on their characteristics, tasting them in person, or watching online videos. Many baristas also prefer to attend classes on the topic, which are provided by a variety of organizations.
