How to Build a Professional Espresso Machine For coffee shops and cafes looking to attract customers with a passion for espresso and barista skills This is a great option. It's the official machine used for World Barista Championships and it truly shows. It has a water reservoir which means that the barista needs to refill it once during their shift. The machine comes with hot water for tea and cool-touch steam wands. Water A commercial espresso machine needs to be able to make large quantities of espresso-based drinks in a timely manner. They are typically made of stainless steel, which is durable and resistant to breaks and scratches. These espresso machines are simpler to maintain and clean. A high-quality machine should have an independent shut-off valve for the water pipe in order to prevent the accumulation of limescale. This will ensure that any repairs are isolated to the affected parts of the machine and won't impact the rest of your operation. When choosing your water ensure that you test it thoroughly and treat it in a way to ensure the best results. Remineralize distilled water by adding a few minerals. This could reduce its erosion properties and improve its flavor, but it may also damage machines. The remineralized water will make the boiler sensor think the machine is full, even though it isn't. This could cause the machine to overheat and become damaged. Grinder The grinder is an essential component of a successful espresso maker. The grinder converts an unground, raw coffee bean into finely-ground coffee which can be tamped correctly into the filter basket for an outstanding extraction. Professional espresso machines of commercial grade typically include a built-in grinder that can be programmed to grind different sizes of drinks, which ensures the same results every time. Super-automatic espresso machines go one step further, automating and programming the entire process from brewing to dispensing. These machines are often praised by Lab tests for being easy to use. A manual or semi-automatic espresso machine requires more involvement by the barista, but the quality of the end result is usually worth it. This model won the 2022 Good Housekeeping Coffee Award for its clever dosing feature that weighs and dispenses the correct amount of ground coffee every time. It also features the ability to use a low pressure pre-infusion to ensure an even extraction, and a milk frother that produced rich, thick steamed-milk in our tests. Temperature When it comes to espresso temperature, it plays an important role in the taste and quality of your shots. If the water isn't at its optimal temperature, it could affect extraction and can cause the coffee being bitter. High-end espresso machines have tools that can help you keep the correct temperature of your water. A PID monitors and regulates temperature of the water. The other way is by using a double boiler system. This allows you to make use of one boiler for steam and tea, while the other heats water to brew temperature. Carles explains how these systems can make a difference for large corporations as well as baristas at home. They can make it easier for beginners to dial in the perfect espresso drink because they can maintain an accurate temperature and avoid a lot of the variables that can throw off the flavor profile. It also makes it easier for experienced baristas to get their shots exactly the way they would like them. Pressure The pressure that an espresso machine is using also affects the quality of the coffee it produces. Many espresso drinkers have noticed that their coffee tastes different depending on the pressure that is used, even though all other variables remain the same. In general, most commercial-grade machines utilize nine bars of pressure to create espresso. These machines tend to be pump-driven instead of steam-driven. Although higher-pressure machines are available however, they require a group head that is more complex to handle the increased levels of pressure. 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 machines that are higher pressure tend to be less expensive and designed for home use. To put 9 bar of pressure into perspective, it's nearly four times the pressure that's exerted by the air in your car tire. The greater the pressure that a professional espresso machine is able to apply more pressure, the better it'll be at capturing the taste of your favorite coffee beans. It's worth investing in high-quality machines that will give you the best results. Barista Skills A barista must be able to accept and process orders of customers quickly and efficiently. This is particularly important when there is a lot of activity at the coffee shop. Good customer service skills is essential to build customer relationships and increasing sales for the shop. espresso coffee machine includes acknowledging regular customers, resolving problems efficiently, and remaining positive and amiable in tough situations. Being able to multitask is often necessary for a barista as they might be required to take orders and operate the cash register, communicate orders to coworkers and respond to phone calls at one time. This skill allows the customer to enjoy an enjoyable experience at the coffee shop by making sure that orders are delivered promptly. It is helpful for baristas to have knowledge of the various kinds of drinks that can be prepared with an espresso machine. This can be mastered by reading up on the different kinds of coffees, trying them out in person, or watching videos online. Many baristas find it helpful to attend classes run by various organizations.
