How to Build a Professional Espresso Machine

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

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

Water

A commercial espresso machine must be able to make a huge amount of espresso-based drinks with efficiency. This is why they are built with stainless steel which is more durable and resistant to scratches and break. These espresso machines are simpler to maintain and clean.

A high-quality machine must include an independent shut-off valve for the water pipe to prevent limescale accumulation. This will ensure that any repairs are confined to the specific machine components and won't affect the rest of your operation.

When you select your water, make sure to test it and treat it properly to ensure the best results. For instance, distilled water can be remineralized by adding a small amount of minerals back to it. It can improve the taste of the water and eliminate its erosive qualities, but could also cause damage to certain machines. The remineralized wate will make the boiler sensor think 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 the success of an espresso machine. It is a process that takes a raw, unground bean and transforms it into finely ground coffee that is then tamped into the filter basket to produce an excellent extraction.

Professional-grade commercial machines include a grinder that can be programmed to accommodate different sizes of drinks. This guarantees consistency in results each time. Super-automatic espresso machine coffee machines go one step further, implementing automation and programmable the entire process from brewing to grinding to dispensing. These machines are often praised during Lab tests for being easy to use.

Manual or semi-automatic machines require more work from the barista, but the results are worth it. This model was awarded an 2022 Good Housekeeping Coffee Award for its dosing technology that weighs and distributes the right amount of ground coffee each time. It also includes a low-pressure pre-infusion mechanism for well-balanced extraction as well as a milk frothing wand that did well in our tests for producing rich, thick steamed milk.

Temperature

When it is time to make espresso, temperature plays a major role in the taste and quality of your coffee. If the temperature of your water is not at a suitable level, it can result in the extraction being impeded and could result in an unpleasant cup.

Fortunately, high-quality espresso machines come with tools that will allow you to keep your water at the correct temperature. One method of doing this is to use PIDs, which monitors and adjusts the temperature of the water. Double boiler systems are a different way to achieve this. One boiler can be used to heat water and steam for tea, and use the other to heat the water to brewing temperature.

Carles explains how these systems can make a difference for both large-scale businesses as well as baristas at home. They can make it easier for newbies to determine the ideal espresso drink because they are able to maintain an exact temperature and eliminate some of the factors that can affect the flavor profile. It can also make it easier for experienced baristas to get their shots exactly how they want them.

Pressure

The amount of pressure an espresso machine uses is another factor that contributes to the quality of the coffee it produces. Many espresso drinkers notice that their beverages taste different based on the amount of pressure they use, even if all other factors remain constant.

Most commercial machines use 9 bars of pressure to brew espresso. These machines are also more likely to be steam-driven rather than pumps-driven. While higher-pressure machines exist they generally require a more intricate group head design that can 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 consistently great brews. The higher-pressure machines tend to be cheaper and designed for use at home.

To put 9 bar of pressure in perspective, it's over four times the amount of pressure that's imposed by the air inside your car tire. The more pressure that a professional espresso maker is able to apply, then the better it is at separating flavor from your favorite coffee beans. It is worth investing in top-quality machines that produce the highest quality results.

Barista Skills

A barista should be able take orders and handle them quickly and precisely. This is especially crucial during busy times at the coffee shop. Excellent customer service skills are crucial for establishing relationships with customers and boosting sales for the coffee shop. This can include acknowledging regular customers, working to resolve issues efficiently and remaining optimistic and amiable in tough situations.

Being able to multitask is often necessary for durable baristas as they may have to take orders and operate the cash register, communicate orders to coworkers and handle phone calls at the same time. This skill allows the customer to enjoy a pleasant coffee shop experience by ensuring that orders are served quickly.

It is crucial that a barista's skills are developed to be able make various types of coffee using an espresso machine. You can learn about the different types of espresso by reading about their characteristics, tasting the drinks in person and by watching online videos. Many baristas also find it beneficial to attend classes on the topic, which are provided by several organizations.
