How to Build a Professional Espresso Machine For coffee shops and cafes seeking to attract customers with passion for espresso and barista abilities, this is a great choice. It's the official machine used for World Barista Championships and it truly shows. The barista can refill the reservoir of water throughout their shift. The machine also features cool-touch steam wands and hot water taps for tea. Water A commercial espresso machine needs to make a large amount of espresso based drinks in an efficient manner. The machines are typically made of stainless steel, which is tough and resistant to cracks and scratches. Stainless steel espresso machines also make it easier to maintain and clean. A good quality machine should include a separate shut-off valve for the water pipe to avoid the build-up of limescale. This will ensure that any repairs will be isolated to the affected machine components and won't impact the rest of your operation. When selecting the water you want to drink be sure to test it and treat it appropriately to get the best results. You can remineralize the water you distill by adding a few minerals. It can enhance the taste and reduce its erosive characteristics, but can also harm certain machines. The remineralized wate will make the boiler sensor think the machine is full, even though it isn't. This could cause the machine to overheat, and eventually be damaged. Grinder The grinder is an essential element in an espresso machine that works. It takes a raw, unground bean and transforms it into a finely ground coffee that can be properly put into the filter basket to create an excellent extraction. Commercial-grade espresso machines usually come with a built-in grinder that can be programmed to grind different sizes of drinks, providing the same results every time. Super-automatic espresso machines go one step further, by automating and programmable the entire process from brewing to dispensing. These kinds of machines usually get high marks in Lab tests due to their hands-off accessibility. Semi-automatic or manual machines demand more work from the barista but often the results are worth the effort. This model was awarded an award called the Good Housekeeping Coffee Award in 2022 for its intelligent dosing system that measures and dispensing the correct amount of coffee every time. It also has a low-pressure pre-infusion system for an even extraction, as well as the milk frothing tool that was a success in our test for producing thick, rich steamed milk. Temperature The temperature is a crucial factor in espresso. If the water isn't at an ideal temperature, it may slow the extraction process and result in a bitter cup of coffee. High-quality espresso machines come with tools to help you maintain the right temperature of your water. One method to achieve this is with a PID, which monitors and adjusts the temperature of the water. The other way is by using a double boiler system. machines espresso allows you to utilize one boiler for steam and tea while the second one heats water to brewing temperatures. Carles mentions that these types of systems can make a big difference for large corporations and baristas working at home. They can make it much easier for newbies to determine the ideal espresso shot since they can keep an exact temperature and eliminate a lot of the variables that can alter the flavor profile. It is also easier for baristas who have more experience to dial in their shots just the way they prefer. 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 different depending on the pressure used, despite the fact that all other factors are constant. In general, most commercial-grade machines use nine bars of pressure to make espresso. These machines also tend to be driven by pumps rather than steam-driven. Although there are machines with higher pressures they generally require a more intricate group head design that can manage the higher pressure levels. While some espresso machines advertise 15 or 18 bars of pressure on their machines nine bars are usually considered to be the gold standard when it comes to making consistently great espressos. These higher-pressure machines are typically less expensive and designed for use at home. To put 9 bars of pressure into perspective, it's four times the amount that's exerted by the air inside your car tire. The greater the pressure an espresso maker with professional quality can apply, then the better it will be in bringing out the flavor of the coffee beans you love. Therefore, it's worth investing in a high-quality machine that can deliver the best results. Barista Skills A barista should be able to take and process orders quickly and precisely. This is particularly important during busy times in the coffee shop. Being able to provide excellent customer service is also crucial for establishing customer relationships and increasing sales for the shop. This includes recognizing regular customers, working to resolve issues efficiently and remaining optimistic and welcoming even in stressful situations. Baristas often need to be skilled at multitasking, since they must take orders and operate a cash counter as well as communicate orders to coworkers and handle phone calls all at once. This ability allows customers to enjoy a pleasant coffee shop experience by ensuring that orders are served promptly. It is helpful for a barista to know the various types of drinks that can be prepared with an espresso machine. This can be gained through studying the various types of coffee, attempting them out in person, or watching videos on the internet. Many baristas find it beneficial to attend classes offered by various organizations.
