How to Build a Professional Espresso Machine
This is an excellent choice for coffee shops and cafes that wish to attract customers who are enthusiastic about barista and espresso skills. It’s the official machine for World Barista Championships, and it shows.
The barista can refill the water reservoir throughout their shift. The machine also features steam wands with cool-touch technology and a hot water tap for tea.
Water
A commercial espresso machine must be able to make a large amount of espresso based drinks efficiently. This is why they are generally constructed from stainless steel, which is more robust and resistant to breaks and scratches. These espresso machines are simpler to maintain and clean.
A high-quality machine must have an additional shut-off valve that is connected to the water pipe in order to prevent the build-up of limescale. This will ensure that any repairs are made to the specific machine components and won’t impact the rest of your operation.
Test your water and ensure it is being treated correctly. For instance distilled water may be restored by adding a tiny amount of minerals back to it. This can negate it’s erosion properties and improve its taste, however it may also damage machines. This is because the remineralized fluid will cause the boiler sensor to think that the machine is filled, when it is not. This can lead to overheating and damage the machine.
Grinder
The grinder is a crucial component of a successful coffee maker. espresso coffee machines turns a raw, unground coffee bean into a finely-ground coffee which can be tamped correctly into the filter basket to ensure an efficient extraction.
Commercial-grade professional espresso machines usually come with a built-in grinder that can be programmed to grind various sizes of drinks, providing consistency in results every time. Super-automatic espresso machines go one step further, by automating and programmable the whole process from brewing to dispensing. These machines are often praised during Lab tests for being easy to use.
Semi-automatic or manual machines require more work from the barista but often the results are worth the effort. This model won a 2022 Good Housekeeping Coffee Award for its dosing technology that weighs and dispensing the correct amount of ground coffee every time. It also comes with a low pressure pre-infusion mechanism for well-balanced extraction as well as a milk frothing wand that was a success in our test for producing thick, rich steamed milk.
Temperature
When it is about espresso, temperature plays a major impact on the flavor and quality of your coffee. If the water isn’t at an ideal temperature, it may hinder extraction and even lead to a bitter cup of coffee.
Espresso machines that are of high-quality come with tools that help you maintain the proper temperature of your water. One method for doing this is with an PID, which monitors and adjusts the temperature of the water. Another method is making use of a double boiler. One boiler can be used to heat steam and water for tea, and use the other to heat water to brewing temperature.
Carles explains that these systems can make a difference for both large-scale businesses as well as baristas working from home. They can make it much easier for novices to determine the ideal espresso drink because they are able to maintain an exact temperature and eliminate a lot of the variables that can alter the flavor profile. It can also make it easier for experienced baristas to get their shots exactly as they want them.
Pressure
The pressure that an espresso machine utilizes can also impact the quality of the coffee it makes. Many espresso drinkers have noticed that their drinks taste differently based on the pressure that is used, even though other factors remain constant.
Most commercial machines use 9 bars of pressure to brew espresso. These machines are also more likely to be steam driven than pump-driven. Although higher-pressure machines are also available however, they require a group head that is more intricate 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. The higher-pressure machines tend to be more affordable and are designed for home use.
To put 9 bars of pressure in perspective, it’s nearly four times the pressure that is exerted by the air inside your car tire. The more pressure a professional espresso maker is able to apply, then the better it will be at separating flavor from your favorite coffee beans. It’s worth investing in a high-quality machine that will deliver the best results.
Barista Skills
Baristas must be able to take orders from customers quickly and accurately. This is especially crucial during busy periods at the coffee shop. A good customer service skill is crucial to build relationships with customers and increasing sales for the coffee shop. This includes recognizing regular customers, resolving issues efficiently and remaining positive and friendly even in challenging situations.
Baristas typically need to be able to multitask, as they must take orders and operate a cash register, communicate orders with coworkers and take phone calls all at once. This ability allows customers to enjoy a pleasant experience in the cafe by making sure that orders are delivered quickly.
It is vital that a barista’s skills are developed to be able to prepare various drinks using an espresso machine. You can learn about the different types of espresso by studying them, trying them in person and watching online videos. Many baristas find it helpful to attend classes offered by various organizations.
