How to Build a Professional Espresso Machine
For coffee shops and cafes looking 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 does show.
It comes with a water reservoir to ensure that the barista only needs to refill it throughout their shift. The machine also comes with steam wands that are cool-touch and a hot water tap for tea.
Water
A commercial decent espresso machine machine needs to make a large amount of espresso based drinks in an efficient manner. This is why they are built with stainless steel which is more durable and resistant to scratches and break. These espresso machines are also easier to maintain and keep clean.
A good quality machine should have a separate shut-off valve to the water pipe to avoid limescale build-up. This will ensure any repairs are only limited to the affected parts of the machine, and will not affect the rest of your operation.
When selecting your water ensure that you test it and treat it properly to get the best coffee espresso machine results. For instance distillate water can be remineralized by adding a small amount of minerals back to it. This can diminish its negative erosive properties and enhance the taste, but it could also cause damage to certain machines. The remineralized wate will make the boiler sensor think the machine is full and it isn’t. This can cause the machine to overheat and cause damaged.
Grinder
The grinder is an essential element of an espresso machine that works. It is a process that takes a raw, unground bean and transforms it into a finely ground coffee that is then put into the filter basket, resulting in an excellent extraction.
Commercial-grade espresso machines usually come with a built-in grinder that can be programmed to grind for various sizes of drinks, which ensures consistent results each time. Super-automatic machines go one step further and automatize the entire process from brewing to grinding and dispensing. These machines are often praised in Lab tests for being easy to use.
A semi-automatic or manual espresso machine requires more involvement by the barista, but the quality of the end result is usually worth it. This model was awarded a Good Housekeeping Coffee Award in 2022 due to its sophisticated dosing mechanism that measures and dispensing the correct amount of coffee each time. It also features an infusion with low pressure for balanced extraction, and the milk frother produced rich, thick steamed-milk during our tests.
Temperature
The temperature is a crucial aspect in retro espresso machine. If the temperature of your water is not at its ideal degree, it can result in the extraction being impeded and can even lead to bitter coffee.
Espresso machines of the highest quality come with tools that help you maintain the proper temperature of your water. One method of doing this is by utilizing PIDs, which monitors and adjusts the temperature of the water. Double boiler systems are another way to accomplish this. This allows you to use a single boiler to steam and tea and the other one to heat water to the right temperature for brewing.
Carles explains that these systems can make a difference for both large businesses and baristas at home. They can make it much easier for newbies to determine the ideal shot of espresso because they can maintain an exact temperature and eliminate a lot of the factors that can affect the flavor profile. It is also easier for baristas who have more experience to get their espressos just how they would like.
Pressure
The pressure an espresso maker makes use of is another element that affects the quality of the coffee it makes. Many espresso drinkers have observed that their drinks taste different based on the amount of pressure used, despite the fact that other factors remain constant.
In general, commercial-grade machines use nine bars of pressure to brew espresso. They also tend to be pump-driven rather than steam-driven. While higher-pressure machines are readily available however, they require a group head that is more complicated to handle the higher levels of pressure.
While you may see some espresso machines advertising 15 or even 18 bars of pressure, nine bars is generally considered the gold standard for creating consistently excellent brews. These machines that are higher pressure are generally cheaper and intended for use at home.
To put 9 bar of pressure in perspective, it’s nearly four times the pressure which is emitted by the air in your car tire. The greater the pressure a professional espresso maker is able to apply, then the better in bringing out the flavor of the coffee beans you love. For this reason, it’s worth investing in a high-end machine that can deliver the best possible results.
Barista Skills
Baristas must be able to accept and process customer orders quickly and espressomachines accurately. This is particularly crucial in busy times in the coffee shop. A good understanding of customer service is also essential for building relationships with customers and generating more business for the shop. This could include recognizing regular customers, working to resolve issues efficiently and remaining optimistic and welcoming even in stressful situations.
Baristas are often adept at multitasking as they are required to take orders as well as operate a cash register and share orders with colleagues and handle phone calls all at once. This skill allows them to keep orders moving quickly to the customer, and gives them an enjoyable time in the coffee shop.
It is vital for baristas in order to make different drinks with an espresso machine. This can be mastered by reading about the various kinds of coffees, trying the drinks in person and watching videos online. Many baristas find it helpful to attend classes provided by various organizations.
