How to Build a Professional Espresso Machine

This is a great option for coffee shops and cafes that want to attract customers who are enthusiastic about espresso and barista skills. It's the official machine for the World Barista Championships, and it shows.

It has a water reservoir to ensure that the barista only needs to refill it once during their shift. The machine has a tea hot water tap and cool-touch steam wands.

Water

A commercial espresso machine is required to create a huge amount of espresso-based drinks in an efficient manner. The machines are typically made of stainless steel, which is strong and resistant against scratches and breaks. These espresso machines are easier to maintain and clean.

A good machine will have a separate shut-off valve for the water line to avoid the formation of limescale. This will ensure that any repairs will be isolated to the affected parts of the machine and won't affect the rest of your operation.

When you select your water ensure that you test it and treat it properly to ensure the best results. For instance distilled water may be restored by adding a tiny amount of minerals back to it. This can negate it's erosive properties and improve its flavor, but it could also cause damage to certain machines. This is because the remineralized fluid will cause the boiler sensor to believe that the machine is fully stocked, but it's not. This can cause excessive heat and damage to the machine.

Grinder

The grinder is an essential element of an espresso machine that works. The grinder converts the raw, unground coffee bean into a finely ground coffee that can be properly tamped into the filter basket for an outstanding extraction.

Commercial-grade professional espresso maker espresso machines typically include a built-in grinder that can be programmed to grind different sizes of drinks, ensuring the same results every time. Super-automatic machines go further and automatize the entire process from brewing, to grinding and dispensing. These machines are often praised by Lab tests for their ease to use.

A semi-automatic or manual espresso capsule machine machine requires more involvement from the barista, however the quality of the final product is often worth it. This model won a Good Housekeeping Coffee Award in 2022 for its intelligent dosing system that measures and distributes the right amount of coffee each time. It also features a low pressure pre-infusion for well-balanced extraction, as well as a milk frother that made rich, thick steamed-milk in our tests.

Temperature

Temperature is a major factor in espresso. If the water isn't at an optimal temperature, it can affect extraction and can result in an unpleasant cup of coffee.

Fortunately, espresso machines of high-end quality have tools that allow you to ensure that your water is at the correct temperature. A PID monitors and regulates the temperature of the water. Double boiler systems are a different way to accomplish this. One boiler can be used to heat water and steam for tea, while using another to heat water to brewing temperature.

Carles explains how these systems can make a difference for large corporations as well as home-based baristas. They can make it simpler for beginners to get the perfect espresso coffee machine with milk frother because they are able to maintain an accurate temperature and avoid some of the variables that can throw off the flavor profile. It helps experienced baristas to get their shots exactly the way they would like them.

Pressure

The pressure that an espresso machine utilizes can affect the quality of coffee it makes. Many espresso drinkers notice that their beverages taste different depending on the amount of pressure employed, even when all other factors remain constant.

In general, commercial-grade machines utilize nine bars of pressure to brew espresso. These machines are also likely to be driven by pumps rather than steam-driven. Although there are machines with higher pressures they generally require a more complicated group head design that can manage the higher pressure levels.

While some espresso machines advertise 15 or 18 bars of pressure on their machines nine bars are usually considered to be the gold standard for making consistently great espressos. These machines that are higher pressure are generally more affordable and are designed to be used at home.

In comparison, 9 bar of pressure is four times higher than the pressure applied by your car tire. The more pressure a professional espresso machine can apply, the better it will be at capturing the flavor of your favorite coffee beans. It is worth investing in top-quality machines that produce the highest quality results.

Barista Skills

A barista must be able to take and process orders quickly and accurately. This is particularly crucial during busy times in the coffee shop. A good understanding of customer service is also crucial for establishing customer relationships and increasing business for the shop. This can include recognizing regular customers, working efficiently to resolve issues, and staying positive and friendly even in challenging circumstances.

Being able 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 take phone calls simultaneously. This ability allows orders to be moving quickly to the customer and ensures that customers have a pleasant experience in the coffee shop.

It is helpful for a barista to be knowledgeable about the various kinds of drinks that can be prepared with an espresso coffee maker machine. You can get acquainted with the different types of espresso by reading up on them, trying them in person, or watching online videos. Many baristas also find it beneficial to attend classes on the topic, which are offered by a variety of organizations.
