How to Build a Professional Espresso Machine

For coffee shops and cafes that want to attract customers with a passion for barista and espresso, this is a great choice. It's the official machine for World Barista Championships, and it shows.

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

Water

A commercial italian espresso machine machine must be able of producing a large volume of espresso-based drinks with efficiency. This is why these machines are typically built from stainless steel which is more durable and resistant to breaks and scratches. Espresso machines made of stainless steel make it easier to clean and maintain.

A good quality machine should have a separate shut-off valve for the water pipe to avoid limescale accumulation. This will ensure that any repairs are only limited to the affected parts of the machine, and will not impact the rest your operation.

When selecting your water make sure 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 into it. This can reduce its anti-erosive properties as well as improve the taste, but it may also damage machines. This is because the remineralized liquid will cause the boiler sensor to think that the machine is fully stocked, but it is not. This could cause the machine to overheat and be damaged.

Grinder

The grinder is an essential component of a successful espresso maker. The grinder transforms the raw, unground coffee bean into a finely -ground coffee that can be tamped properly into the filter basket to ensure an excellent extraction.

Professional espresso machines of commercial grade typically have a built-in grinding unit that can be programmed to grind for various drink sizes, ensuring consistent results each time. Super-automatic espresso machines go one step further, by automating and programmable the whole process from brewing to dispensing. These kinds of machines typically get high marks in Lab tests due to their hands-off user-friendliness.

Semi-automatic or manual machines require more work from the barista, but the results are worth it. This model earned an 2022 Good Housekeeping Coffee Award for its dosing technology that weighs and dispenses the correct amount of ground coffee every time. It also includes a low-pressure pre-infusion system to ensure an even extraction, as well as an ice cream wand that did well in our tests for producing rich, thick steaming milk.

Temperature

When it comes to espresso temperature, it plays an important role in the taste and quality of your coffee. If the water temperature is not at a suitable degree, it can result in the extraction being impeded and may even result in a bitter cup.

Fortunately, espresso machines of high-end quality come with tools that enable you to ensure that your water is at the correct temperature. A PID monitors and regulates the temperature of water. The other way is by using a double boiler. You can use one dual boiler espresso machine to heat water and steam for tea, while using the other to heat water to brewing temperature.

Carles points out that these systems can make a big difference for large corporations and home baristas alike. They can assist novices to dial in the perfect espresso shot since they are able to maintain an exact temperature and eliminate numerous variables that could affect the flavor quality. It is also much easier for baristas with more experience to dial in their shots just the way they prefer.

Pressure

The pressure an espresso machine is using can also impact the quality of coffee it makes. Many espresso drinkers have noticed that their drinks taste differently depending on the amount pressure used, even if all other factors are constant.

In general, commercial-grade machines use nine bars of pressure to make espresso. These machines also tend to be pump-driven, not steam-driven. While higher-pressure machines are readily available, they require a group head that is more complex to handle the higher levels of pressure.

While you may see espresso machines advertising 15 or even 18 bars of pressure, nine bars are generally considered to be the gold standard for making consistently excellent brews. These higher-pressure machines are typically smaller and designed to be used at home.

In comparison, 9 bar of pressure is four times greater than the pressure exerted by your car tire. The more pressure a professional espresso maker (their explanation) can apply, then the better it is at extracting flavor out of your favorite coffee beans. This is why it's worth investing in a high-end machine that can give you the highest quality results.

Barista Skills

A barista must be able to take and process customer orders quickly and efficiently. This is particularly important in busy times at the coffee shop. Good customer service skills are crucial for establishing relationships with customers and increasing the sales of the coffee shop. This includes recognizing frequent customers, working efficiently to resolve issues, and staying positive and friendly even in the most difficult of situations.

Being able to multitask is a must for a barista, as they may have to take orders and operate the cash counter and communicate orders to colleagues and answer phone calls at one time. This skill allows them to keep orders moving quickly to the customer and gives them an enjoyable experience at the coffee shop.

It is vital for a barista's education to be able make different types of drinks using an espresso machine. This can be gained through researching the different types of coffee, trying them out in person and watching videos on the internet. Many baristas prefer to attend classes on the topic, which are provided by various organizations.
