How to Build a Professional Espresso Machine This is an excellent choice for cafes and coffee shops that want to attract customers who are enthusiastic about espresso and barista skills. It's the official machine of the World Barista Championships and it truly shows. The barista can refill the reservoir of water throughout their shift. The machine has hot water for tea and steam wands that cool-touch. Water A commercial espresso machine should be able to make an enormous amount of espresso-based drinks efficiently. That's why these machines are built with stainless steel which is more durable and resistant to breakage and scratches. Espresso machines made of stainless steel make it easier to clean and maintain. A high-quality machine must have an independent shut-off valve for the water pipe to avoid the build-up of limescale. This will ensure any repairs are limited to affected parts of the machine and not impact the rest your operation. When selecting the water you want to drink make sure you test it and treat it properly to ensure the best results. For example the distilled water can be remineralized by adding a small amount of minerals back to it. It can improve the taste and reduce its erosive properties, however it can also damage certain machines. The remineralized water will make the boiler sensor think that the machine is full however it's not. This can lead to excessive heat and damage to the machine. Grinder The grinder is a crucial element of the success of an espresso machine. The grinder turns the unground, raw coffee bean into a finely-ground coffee which can be tamped correctly into the filter basket to ensure an excellent extraction. Commercial-grade professional machines include grinders that can be programmed to accommodate different sizes of drinks. This ensures consistent results every time. Super-automatic espresso machines take this one step further, implementing automation and programming the entire process from brewing to grinding to dispensing. These kinds of machines tend to earn high marks in Lab tests due to their hands-free simplicity of use. A manual or semi-automatic espresso machine requires more involvement from the barista, but the quality of the final result is usually worth it. This model won a 2022 Good Housekeeping Coffee Award for its dosing technology that weighs and dispenses the correct amount of ground coffee each time. It also comes with a low-pressure pre-infusion mechanism for smooth extraction and the milk frothing wand, which did well in our tests for producing rich, thick steaming milk. Temperature When it is time to make espresso temperature, it plays an important factor in the taste and quality of your coffee. If the water temperature is not at the right degree, it can cause extraction to be hindered and may even result in an unpleasant cup. Fortunately, top-quality espresso machines come with tools that enable you to keep your water at the correct temperature. A PID monitors and regulates temperature of water. The other way is by utilizing a double boiler system. One boiler can be used to heat steam and water for tea, and use another for heating water to brewing temperature. Carles states that these systems can make a difference for large companies as well as home baristas. They can make it simpler for beginners to determine the ideal espresso shot because they maintain an exact temperature and eliminate some of the variables that can throw off the flavor profile. It is also much easier for baristas with more experience to get their shots just the way they prefer. Pressure The pressure that an espresso machine uses can affect the quality of coffee it makes. Many espresso drinkers notice that their drinks taste different based on the amount of pressure that is used, even though all other factors remain the same. In general, commercial-grade machines utilize nine bars of pressure to make espresso. These machines are also more likely to be steam-driven rather than pumps driven. Although high-pressure machines are offered but they require a group head that is more sophisticated to handle the increased levels of pressure. While you may see espresso machines that advertise 15 or even 18 bars of pressure, nine bars is generally regarded as the gold standard for creating consistently excellent brews. These higher-pressure machines are typically more affordable and are designed to be used at home. To put 9 bar of pressure into perspective, it's four times the amount that is exerted by the air inside your car tire. The greater the pressure that a professional espresso machine can put on more pressure, the better it'll be at extracting flavor from the coffee beans you love. 9 bar espresso machine is why it's worth investing in a premium machine that can give you the highest quality results. Barista Skills A barista should be able to handle orders quickly and accurately. This is particularly important in busy times in the coffee shop. A good understanding of customer service is also essential for building relationships with customers and increasing sales for the shop. This can include recognizing regular customers, working efficiently to resolve problems and remaining friendly and positive in the most difficult of situations. Baristas often need to be able to multitask, as they have to take orders, operate a cash register, communicate orders with coworkers, and answer telephone calls all at once. This skill allows the customer to enjoy a pleasant experience in the cafe by ensuring that orders are served quickly. It is crucial for a barista's knowledge to be able to make various types of coffee using an espresso machine. This can be learned by reading about the various types of coffee, attempting them out in person, or watching videos online. Many baristas find it helpful to attend classes offered by various organizations.
