How to Build a Professional Espresso Machine

This is a great choice for cafes and coffee shops who want to attract customers who are enthralled by espresso and barista abilities. It's the official barista machine for World Barista Championships and it really does show.

The barista can refill the water reservoir throughout their shift. It also has cool-touch steam wands and a hot water tap for tea.

Water

A commercial espresso machine is required to create a huge amount of espresso based drinks efficiently. The machines are typically made of stainless steel, which is tough and resistant to breaks and scratches. These espresso machines are also easier to maintain and keep clean.

A good machine has a shut-off valve for the water line to avoid the formation of limescale. This will ensure that any repairs are made to the specific machine components and won't affect the rest of your operation.

Test your water and ensure it is being treated correctly. For instance, distilled water can be recycled by adding a small amount of minerals back to it. This can reduce its erosive properties and improve its taste, however it may also damage machines. This is because the remineralized fluid will cause the boiler sensor to think that the machine is full, even though it's not. This can cause the machine to overheat, and eventually be damaged.

Grinder

The grinder is a crucial element for an espresso machine that works. The grinder transforms the raw, unground coffee bean into a finely -ground coffee which can be tamped correctly into the filter basket for an excellent extraction.

Professional commercial machines come with a grinder that can be programmed to work with different sizes of drink. This ensures the same results every time. Super-automatic espresso machines go one step further, automating and programmable the entire process from brewing to grinding to dispensing. These machines are often praised in Lab tests for their ease to use.

A manual or semi-automatic espresso machine requires more involvement by the barista, but the quality of the end result is often worth the effort. This model was awarded the 2022 Good Housekeeping coffee espresso machine Award for its clever dosing feature which weighs and delivers the right amount of ground coffee each time. It also has a low pressure pre-infusion for an even extraction, and an milk frother that created dense, thick steamed milk during our tests.

Temperature

Temperature is a key element in espresso. If the water isn't at an optimal temperature, it can hinder extraction and even cause a bitter cup of coffee.

Fortunately, high-quality espresso machines have tools that allow you to ensure that your water is at the correct temperature. A PID monitors and regulates temperature of water. Double boiler systems are a second method to do this. One boiler can be used to heat steam and water for tea, and use the other for heating water to brewing temperature.

Carles says that these kinds of systems can make the difference for large businesses as well as home baristas. They can make it easier for beginners to get the perfect espresso because they maintain an exact temperature and eliminate some of the variables that can throw off the flavor profile. It helps experienced baristas to create their shots exactly as they want them.

Pressure

The pressure that an espresso machine employs is another factor that affects the quality of the coffee it makes. Many espresso drinkers have noticed that their drinks have a distinct taste different based on the amount of pressure they use, even if all other elements remain the same.

The majority of commercial machines utilize 9 bars of pressure to brew espresso. These machines are also likely to be pump-driven, not steam-driven. While higher-pressure machines exist they generally require a more sophisticated group head design that can handle the higher pressure levels.

While some espresso machines advertise 15 or 18 bars of pressure in their machines nine bars are usually considered to be the standard for creating consistently great brews. The higher-pressure machines tend to be more affordable and designed for home use.

To put 9 bar of pressure in perspective, it's more than four times the amount of pressure that's exerted by the air in your car tire. The more pressure an experienced espresso home machine machine can exert, the better it will be at capturing the taste of the coffee beans you love. This is why it's worth investing in a high-end machine that will deliver the best results.

Barista Skills

A barista needs to be able take and process orders quickly and accurately. This is especially important in busy times at the coffee shop. A good understanding of customer service is essential to build relationships with customers and increasing sales for the shop. This includes acknowledging regular customers, working to resolve problems efficiently, and remaining positive and welcoming even in stressful situations.

Baristas typically need to be capable of multitasking, as they are required to take orders and operate a cash register, communicate orders with coworkers and handle phone calls at the same time. This ability helps keep orders moving quickly to the customer and gives them an enjoyable experience in the coffee shop.

It is crucial for a barista's education to be able to prepare different drinks with an espresso machine. This can be gained through reading up on the different kinds of coffee, testing the drinks in person and watching videos on the internet. Many baristas find it helpful to take classes offered by various organizations.
