How to Build a Professional Espresso Machine For coffee shops and cafes that want to attract customers with a passion for espresso and barista abilities, This is a great option. It's the official barista machine for World Barista Championships and it really shows. The barista can refill the water reservoir during their shift. The machine comes with a hot water tap for tea and steam wands with cool-touch. Water A commercial espresso machine has to be able to create a huge amount of espresso-based drinks in a timely manner. This is why these machines are typically built from stainless steel which is more durable and resistant to breakage and scratches. Stainless steel espresso machines also make it easier to maintain and clean. A high-quality machine should include a separate shut-off valve to the water pipe, to prevent the build-up of limescale. This will ensure that any repairs are made to the affected components of the machine and won't impact the rest of your operation. Check your water and make sure it is treated properly. For example, distilled water can be recycled by adding a small amount of minerals back into it. This can reduce its erosive properties and improve its taste, but it could also cause damage to certain machines. The remineralized water will make the boiler sensor think that the machine is full even though it's not. This could cause the machine to overheat, and eventually be damaged. Grinder The grinder is a key component of an espresso machine that is successful. It takes a raw, unground bean and turns it into a finely ground coffee that can be properly placed into the filter basket, resulting in an excellent extraction. Professional commercial machines come with grinders that can be programmed to accommodate different sizes of drinks. This guarantees consistency in results each time. Super-automatic espresso machines go one step further, by automating and programming the entire process from brewing to grinding to dispensing. These kinds of machines usually get high scores in Lab tests for their hands-off ease of use. A manual or semi-automatic espresso machine requires more involvement by the barista, but the quality of the final result is often worth it. This model won a 2022 Good Housekeeping Coffee Award for its dosing technology that weighs and dispensing the right amount of ground coffee each time. It also comes with a low-pressure pre-infusion system that allows for smooth extraction and the milk frothing tool that performed well in our tests for producing rich, thick steaming milk. Temperature The temperature is a crucial factor in espresso. If the temperature of the water isn't at a good level, it could cause extraction to be hindered and can even lead to bitter cups. High-quality espresso machines come with tools that can help you keep the correct temperature of your water. One method of doing this is with an PID, which monitors and adjusts the temperature of the water. Double boiler systems are a second method to achieve this. You can use one boiler to heat steam and water for tea, and use the second boiler to heat water to the brewing temperature. Carles explains that these systems can be beneficial for both large-scale businesses as well as baristas who work from home. They make it easier for novices to dial in the perfect shot of espresso because they are able to maintain an accurate temperature and avoid a lot of the variables that can throw off the flavor profile. It can also make it easier for experienced baristas to create their shots exactly the way they want them. Pressure The pressure that an espresso machine uses also affects the quality of the coffee it produces. Many espresso drinkers have noticed that their drinks taste different depending on the pressure employed, even when all other variables remain the same. The majority of commercial machines utilize 9 bars of pressure to make espresso. They also tend to be driven by pumps rather than steam-driven. Although higher-pressure machines are available, they require a group head that is more intricate to handle the higher 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 gold standard when it comes to making consistently great espressos. These higher-pressure machines are typically less expensive and designed for home use. In comparison, 9 bars of pressure is four times higher than the pressure applied by your car tire. The greater the pressure that a professional espresso machine is able to apply and the more effective it will be at capturing the taste of your favorite coffee beans. It's worth investing in top-quality machines that can give the highest quality results. Barista Skills A barista needs to be able to take orders from customers quickly and efficiently. This is particularly crucial during busy times at the coffee shop. Being able to provide excellent customer service is also crucial for establishing relationships with customers and increasing sales for the shop. This can include acknowledging regular customers, working to resolve issues quickly and remaining positive and amiable in tough situations. Baristas often need to be capable of multitasking, as they are expected to take orders and operate a cash counter as well as communicate orders to coworkers, and answer telephone calls at the same time. This skill helps keep orders moving quickly to the customer, and will allow them to have a pleasant experience in the coffee shop. It is important for a barista to be knowledgeable about the various types of drinks that can be made with an espresso machine. This can be mastered by reading up on the different types of coffee, attempting them out in person, or watching videos on the internet. Baristas often find it beneficial to attend classes on the matter, offered by many organizations.
