How to Build a Professional Espresso Machine For coffee shops and cafes looking to attract customers who have a passion for espresso and barista abilities, this is a great option. It's the official barista machine for World Barista Championships and it truly shows. It comes with a water reservoir so that the barista only needs to refill it throughout their shift. The machine also has cool-touch steam wands and hot water taps for tea. Water A commercial espresso machine needs to be able of producing a large volume of espresso-based drinks in a timely manner. They are typically made of stainless steel, which is tough and resistant against cracks and scratches. Stainless steel espresso machines also make it easier to clean and maintain. A high-quality machine should have a separate shut-off valve for the water pipe, to prevent limescale build-up. This will ensure any repairs are only limited to the affected components of the machine and won't affect the operation of the rest. Test your water to ensure that it has been treated properly. For instance, distilled water can be recycled by adding a small amount of minerals back into it. It can improve the taste and negate its erosive qualities, but could also cause damage to certain machines. This is because the remineralized water will cause the boiler sensor to believe that the machine is full when it's not. This could cause excessive heat and damage to the machine. Grinder The grinder is a crucial component of a successful espresso maker. It takes a raw, unground bean and transforms it into finely ground coffee that is then placed into the filter basket for an excellent extraction. Professional-grade commercial machines include grinders that can be programmed for different drink sizes. This ensures the same results every time. Super-automatic espresso machines go one step further, by automating and programming the entire process from brewing to dispensing. These kinds of machines tend to earn high marks in Lab tests due to their hands-off accessibility. A semi-automatic or manual espresso machine requires more involvement from the barista, however the quality of the final result is often worth it. This model won an 2022 Good Housekeeping Coffee Award for its clever dosing feature which weighs and delivers the right amount of ground coffee every time. It also features an low-pressure pre-infusion system for balanced extraction, and the milk frother produced rich, thick steamed-milk in our tests. Temperature Temperature is a key aspect in espresso. If the water isn't at its optimal temperature, it could slow the extraction process and result in bitter coffee. Fortunately, high-quality espresso machines include tools that allow you to ensure that your water is at the correct temperature. A PID monitors and regulates temperature of the water. Double boiler systems are a second method to accomplish this. This lets you utilize one boiler for tea and steam and the other one to heat water to brew temperature. Carles explains how these systems can be beneficial for large corporations as well as baristas working from home. They can help novices dial in the perfect espresso shot since they maintain an exact temperature while avoiding various variables that can alter the flavor quality. It is also easier for baristas who have more experience to make their espressos just the way they want. Pressure The pressure an espresso machine uses is another factor that influences the quality of the coffee it makes. Many espresso drinkers notice that their beverages taste different depending on the amount of pressure used, even when all other variables remain the same. Most commercial machines use 9 bars of pressure to brew espresso. These machines are also more likely to be steam-driven instead of pump-driven. While there are higher-pressure machines they generally require a more complicated group head design to handle the higher pressure levels. While you may see espresso machines that advertise 15 or even 18 bars of pressure, nine bars is generally considered the gold standard for creating consistently great brews. These machines with higher pressure tend to be less expensive and are designed for home use. To put 9 bar of pressure into perspective, it's over four times the pressure that's exerted by the air inside your car tire. The greater pressure a professional espresso machine can put on to the coffee, the better it will be at capturing the taste of your favorite coffee beans. It's worth investing in a high-end machine that will deliver the most effective results. Barista Skills A barista needs to be able take orders and process them quickly and accurately. This is particularly crucial in busy times at the coffee shop.

The ability to multitask is often required for baristas as they may be required to take orders and operate the cash register and also communicate orders to their coworkers and answer phone calls at the same time. This skill allows the customer to enjoy a pleasant experience in the cafe by ensuring that orders are delivered quickly. It is important that a barista's skills are developed in order to make various types of coffee using an espresso machine. Learn about the various kinds of espresso by reading up on them, experimenting with the drinks in person and by watching online videos. Many baristas find it helpful to attend classes offered by various organizations.
