How to Build a Professional Espresso Machine
This is a fantastic option for coffee shops and cafes that wish to attract customers who are enthusiastic about espresso and barista skills. It's the official machine used for World Barista Championships and it truly shows.
The barista is able to refill the reservoir with water throughout their shift. The machine comes with a hot water tap for tea and cool-touch steam wands.
Water
A commercial espresso machine is required to make a large amount of espresso based drinks efficiently. That's why they are usually constructed of stainless steel, which is more robust and resistant to scratches and breaks. Espresso machines made of stainless steel make it easier to clean and maintain.
A high-quality machine should have a separate shut-off valve for the water pipe in order to prevent the build-up of limescale. This will ensure any repairs are limited to affected components of the machine and not affect the operation of the rest.
Check your water and make sure it is being treated correctly. You can remineralize distilled water by adding a few minerals. It can enhance the taste of the water and eliminate its erosive qualities, but could also cause damage to 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 could cause the machine to overheat and be damaged.
Grinder
The grinder is a key element in an espresso machine that is successful. It takes a raw, unground bean and transforms it into finely ground coffee that can then be placed into the filter basket to create an excellent extraction.
Commercial-grade professional espresso machines usually come with a built-in grinder that can be programmed to grind various drink sizes, ensuring the same results every time. Super-automatic espresso machines go one step further, automating and programming the entire process from brewing to dispensing. These kinds of machines are able to score high scores in Lab tests for their hands-off ease of use.
A semi-automatic or manual espresso machine requires more involvement from the barista, however the quality of the end product is often worth it. This model was awarded the 2022 Good Housekeeping Coffee Award for its dosing technology which weighs and delivers the correct amount of ground coffee every time. It also features an low-pressure pre-infusion system for an even extraction, and a milk frother that made rich, thick steamed-milk during our tests.
Temperature
Temperature is an important element in espresso. If the temperature of the water is not at a suitable degree, it can cause extraction to be impeded and even result in bitter cups.
Espresso machines of the highest quality come with tools to help website you maintain the proper temperature of your water. A PID monitors and regulates the temperature of the water. Double boiler systems are another way to do this. One boiler can be used to heat steam and water for tea, while using the other to heat water to the brewing temperature.
Carles explains how these systems can be beneficial for both large businesses and home-based baristas. They make it easier for beginners to dial in the perfect espresso because they can maintain an exact temperature and eliminate some of the variables that can throw off 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 uses is another factor that affects the quality of the coffee it produces. Many espresso drinkers notice that their coffees taste different depending on the pressure that is used, even though all other variables remain the same.
Most commercial machines use 9 bars of pressure in order to make espresso. These machines are also more likely to be steam-driven rather than pumps-driven. Although higher-pressure machines are available but they usually require a more complicated group head design to handle the increased pressure levels.
While some espresso machines advertise 15 or 18 bars of pressure on their machines, nine bars are generally considered to be the standard when it comes to making consistently excellent brews. These higher-pressure machines tend to be cheaper and are designed for home use.
To put 9 bars of pressure in perspective, it's four times the amount that's imposed by the air inside your car tire. The greater the pressure a professional espresso maker can apply, the more effective it is at extracting flavor out of the coffee beans you love. It's worth investing in top-quality machines that will give you the best results.
Barista Skills
A barista should be able take and process orders quickly and precisely. This is particularly important during busy times in the coffee shop. A good customer service skill is essential for building relationships with customers as well as increasing the sales of the coffee shop. This could include recognizing regular customers, working efficiently to resolve problems and staying positive and friendly even when faced with difficult situations.
Baristas are often capable of multitasking, as they are required to take orders and operate a cash register as well as communicate orders to coworkers and respond to phone calls at the same time. This skill allows the customer to enjoy a pleasant experience in the cafe by ensuring that orders are delivered quickly.
It is essential for a barista's knowledge in order to make different drinks with an espresso machine. You can find out about the various kinds of espresso by reading up on their characteristics, tasting them in person and watching online videos. Baristas often consider it beneficial to attend classes on the subject, which are offered by many organizations.
