How to Build a Professional Espresso Machine
For coffee shops and cafes that want to attract customers with passion for barista and espresso skills, this is a great choice. It's the official machine for the World Barista Championships, and it shows.
The barista can refill the water reservoir throughout their shift. The machine also features cool-touch steam wands and a hot water tap for tea.
Water
A commercial espresso machine needs to produce a high volume of espresso-based drinks efficiently. This is why they are usually constructed of stainless steel, which is more robust and resistant to scratches and break. Espresso machines are also easy to maintain and clean.
Lastly, a good quality machine will have a separate shut off valve for the water line, to prevent the build-up of limescale. This will ensure that any repairs are made to the affected parts of the machine and won't impact the remainder of your operation.
Check your water to ensure it's being treated correctly. For example, distilled water can be refining by adding a small amount of minerals back into it. This can diminish its negative erosive properties and enhance its taste, however it could also harm certain machines. This is because the remineralized water will cause the boiler sensor to believe that the machine is filled, when it is not. This can cause the machine to overheat, and eventually be damaged.
Grinder
The grinder is an essential component of a successful coffee maker. The grinder converts an unground, raw coffee bean into a finely -ground coffee which can be tamped correctly into the filter basket to ensure an excellent extraction.
Professional commercial machines come with grinders that are programmed for various sizes of drinks. This guarantees consistency in results each time. Super-automatic espresso machines take this one step further, by automating and programmable the entire process from brewing to grinding to dispensing. These kinds of machines usually get high marks in Lab tests due to their hands-off simplicity of use.
A semi-automatic or manual espresso machine requires more involvement by the barista, but the quality of the final result is often worth the effort. This model was awarded the Good Housekeeping Coffee Award in 2022 for its intelligent dosing system that measures and delivers the correct amount of coffee every time. It also features an infusion with low pressure for balanced extraction, and an milk frother that created dense, thick steamed milk during our tests.
Temperature
The temperature is a crucial factor in espresso. If the water isn't at its ideal temperature, it can hinder extraction and even lead to a bitter cup of coffee.
Fortunately, high-quality espresso machines include tools that allow you to keep your water at the right temperature. A PID monitors and regulates the temperature of water. Another option is using a double boiler system. This allows you to utilize one boiler for tea and steam and the other for heating water to the right temperature for brewing.
Carles states that these systems can make a difference for large-scale businesses and baristas working at home. They can make it simpler for newbies to make the perfect espresso drink because they can maintain an accurate temperature and avoid a lot of the factors that can alter the flavor profile. It helps experienced baristas to create their shots exactly the way they want them.
Pressure
The pressure an espresso machine utilizes can also impact the quality of the coffee it produces. Many espresso drinkers have noticed that their drinks taste differently based on the pressure they use, even if all other variables remain the same.
The majority of commercial machines utilize 9 bars of pressure in order to make espresso. These machines tend to be pump-driven rather than steam-driven. Although higher-pressure machines are also available however they require a group head that is more intricate to handle the increased levels of pressure.
While some espresso machines advertise 15 or 18 bars of pressure on their machines 9 bars are typically considered to be the standard for creating consistently great brews. These higher-pressure machines are typically smaller and designed to be used at home.
In comparison, 9 bars of pressure is 4 times more than the pressure that is exerted by your car tire. The greater pressure a professional espresso machine can exert more pressure, the better it'll be at capturing the taste of the coffee beans you love. It's worth investing in top-quality machines that will give you the best results.
Barista Skills
Baristas must be able to take orders from customers quickly and accurately. This is especially crucial in busy times at the coffee shop. Excellent customer service skills are essential for building relationships with customers as well as increasing sales for the coffee shop. This could include recognizing regular customers, working effectively to resolve issues, and remaining friendly and positive in the most difficult of situations.
The ability to multitask is often required for a barista, as they may be required to take orders and operate the cash counter and also communicate orders to their coworkers and answer phone calls at the same time. This skill helps keep orders moving quickly to the customer, and gives them an enjoyable time in the coffee shop.
It is essential for a barista to be aware of the various kinds of drinks that can be made by an espresso machine. You can learn about the different types of espresso by reading about them, trying them in person, and watching online videos. Many baristas also find it beneficial to attend classes on the matter, offered by various organizations.
