How to Build a Professional Espresso Machine

For coffee shops and cafes seeking to attract customers with a love of barista and espresso skills, this is a great choice. It's the official machine used for World Barista Championships, and it shows.

It comes with a water reservoir which means that the barista needs to refill it once during their shift. The machine also features cool-touch steam wands and a hot water tap for tea.

Water

A commercial espresso machine has to make a large amount of espresso based drinks in an efficient manner. This is why these machines are usually constructed of stainless steel, which is more durable and resistant to scratches and breaks. These espresso machines are also easy to maintain and clean.

Lastly, a good quality machine will have a separate shut-off valve for the water line in order to prevent limescale build up. This will ensure that any repairs are made to the affected machine components and won't impact the rest of your operation.

When selecting the water you want to drink ensure that you test it and treat it correctly to ensure the best espresso machine results. Remineralize distilled water by adding a few minerals. This can negate it's negative erosive properties and enhance its taste, however it could also harm certain machines. The remineralized wate can make the boiler sensor believe that the machine is full, even though it isn't. This can cause the machine to overheat, and eventually be damaged.

Grinder

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

Commercial-grade professional machines include grinders that can be programmed for different drink sizes. This ensures constant 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.

Semi-automatic or manual machines require more work from the barista but often the results are worth it. This model won an 2022 Good Housekeeping Coffee Award for its smart dosing feature that weighs and dispensing the right amount of ground coffee each time. It also includes a low-pressure pre-infusion system to ensure an even extraction, as well as the milk frothing wand, which did well in our tests for producing thick, rich steamed milk.

Temperature

When it comes to espresso, temperature plays a major impact on the flavor and quality of your shots. If the water temperature is not at the right level, it may cause extraction to be impeded and may even result in bitter cups.

Luckily, the best espresso machines include tools that allow you to keep your water at the right temperature. One method to achieve this is to use an PID, which monitors and adjusts the temperature of the water. Double boiler systems are a second method to accomplish this. One boiler can be used to heat water and steam for tea, and use another for heating water to brewing temperature.

Carles explains that these systems can make a difference for large companies as well as baristas at home. They can help novices dial in the perfect espresso drink because they are able to maintain an exact temperature and eliminate many variables that can affect the flavor profile. It helps baristas with experience to get their espressos exactly how they would like them.

Pressure

The pressure that the espresso machine makes use of can affect the quality of coffee it produces. Many espresso drinkers notice that their coffees taste different based on the pressure employed, even when all other factors remain constant.

In general, commercial grade machines use nine bars of pressure to make espresso. These machines are also more likely to be steam-driven instead of pumps-driven. Although higher-pressure machines are available but they require a group head that is more complicated to handle the increased levels of pressure.

While some espresso machines advertise 15 or 18 bars of pressure in their machines Nine bars are generally considered to be the gold standard when it comes to creating consistently great brews. These machines that are higher pressure are generally cheaper and intended to be used 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 the coffee beans you love. Therefore, it's worth investing in a premium machine that will deliver the most effective results.

Barista Skills

A barista needs to be able take orders and process them quickly and precisely. This is particularly crucial in busy times at the coffee shop. Excellent customer service skills are also important for building relationships with customers and boosting sales for the coffee shop. This includes acknowledging regular customers, working efficiently to resolve problems and remaining positive and friend even in challenging circumstances.

Being able to multitask is often necessary for a barista as they might be required to take orders and operate the cash counter and then communicate orders to coworkers and answer phone calls at the same time. This ability allows orders to be moving quickly to the customer, and will allow them to have an enjoyable experience at the coffee shop.

It is important for a barista to know the various kinds of drinks that can be prepared with an espresso coffee machine machine. This can be accomplished by studying the various types of coffee, attempting them out in person, or watching videos online. Many baristas find it helpful to take classes offered by various organizations.
