How to Build a Professional Espresso Machine For cafes and coffee shops that want to attract customers with a passion for espresso and barista skills This is a great option. It's the official barista machine for World Barista Championships and it really does show. The barista can refill the reservoir of water throughout their shift. The machine comes with hot water for tea and steam wands that cool-touch. Water A commercial espresso machine has to be able of producing an enormous amount of espresso-based drinks efficiently. That's why these machines are generally constructed from stainless steel which is more durable and resistant to scratches and break. Espresso machines made of stainless steel make it easier to keep clean and maintained. Lastly, a good quality machine will have a separate shut off valve for the water line in order to prevent limescale build up. This will ensure any repairs are only limited to the affected components of the machine and will not affect the rest of your operation. When you select your water ensure that you test it and treat it correctly to get the best results. For instance, distilled water can be refining by adding a small amount of minerals back into it. This can reduce its negative erosive properties and enhance the taste, but it could also cause damage to certain machines. The remineralized water will make the boiler sensor think the machine is full however it's not. This can cause the machine to overheat and cause damaged. Grinder The grinder is an essential part of a successful espresso maker. It grinds a raw bean and transforms it into a finely ground coffee that can be properly tamped into the filter basket, resulting in an excellent extraction. Commercial-grade professional machines include grinders that are 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 are able to score high marks in Lab tests due to their hands-free user-friendliness. A semi-automatic or manual espresso machine requires more involvement by the barista, but the quality of the final result is often worth it. This model won an award known as the Good Housekeeping Coffee Award in 2022 for its clever dosing system, which measures and dispenses the right amount of coffee every time. It also comes with the ability to use a low pressure pre-infusion to ensure balanced extraction, and the milk frother produced rich, thick steamed-milk in our tests. Temperature Temperature is an important factor in espresso. If the water isn't at its ideal temperature, it can hinder extraction and even result in the coffee being bitter. Espresso machines of the highest quality come with tools to help you maintain the proper temperature of your water. One method to achieve this is by using an PID, which monitors and adjusts the temperature of the water. The other way is by making use of a double boiler. This allows you to utilize one boiler for tea and steam and the other one to heat water to the right temperature for brewing. Carles states that these systems can be beneficial for large-scale businesses and baristas working at home. They make it easier for beginners to determine the ideal espresso shot because they are able to maintain an exact temperature and eliminate some of the factors that can alter the flavor profile. It's also much easier for baristas with more experience to get their espressos just how they prefer. Pressure The pressure that an espresso machine uses is another aspect that influences the quality of the coffee it produces. Many espresso drinkers have noticed that their drinks taste different based on the pressure they use, even if all other elements remain the same. In general, commercial-grade machines utilize nine bars of pressure to brew espresso. These machines are also likely to be pump-driven, not steam-driven. While there are higher-pressure machines however, they typically require a more intricate group head design to handle the increased pressure levels. While you may see espresso machines that advertise 15 or even 18 bars of pressure, nine bars are generally considered the most reliable standard for producing consistently excellent brews. These machines that are higher pressure are generally cheaper and intended for use at home. To put 9 bar of pressure in perspective, it's more than four times the amount which is emitted by the air in your car tire. The more pressure an experienced espresso machine can apply more pressure, the better it'll be at capturing the taste of the coffee beans you love. Therefore, it's worth investing in a high-quality machine that can deliver the highest quality results. Barista Skills A barista must be able to handle orders quickly and precisely.

This ability allows orders to be moving quickly to the customer, and gives them an enjoyable experience at the coffee shop. It is vital that a barista's skills are developed in order to make different types of drinks using an espresso machine. You can get acquainted with the various types of espresso by reading about the various types, trying them in person, or watching online videos. Many baristas also consider it beneficial to attend classes on the topic, which are provided by several organizations.
