How to Build a Professional Espresso Machine

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

The barista can refill the water reservoir during their shift. The machine also comes with steam wands with cool-touch technology and a hot water tap for tea.

Water

A commercial espresso machine has to create a huge amount of espresso-based drinks efficiently. That's why these machines are usually constructed of stainless steel, which is more robust and resistant to scratches and break. Stainless steel espresso machines also make it easier to maintain and clean.

A high-quality machine should have an additional shut-off valve that is connected to the water pipe to avoid limescale build-up. This will ensure any repairs are limited to affected components of the machine and will not impact the rest your operation.

Check your water to ensure it's being treated correctly. You can remineralize the water you distill by adding some minerals. This can diminish its anti-erosive properties as well as improve its flavor, but it could also harm certain machines. This is because the remineralized water can cause the boiler sensor to think that the machine is full, even though it's not. This can lead to excessive heat and damage to the machine.

Grinder

The grinder is an essential element of the success of an espresso machine. The grinder transforms the raw, unground coffee bean into a finely -ground coffee which can be tamped correctly into the filter basket to ensure the best extraction.

Professional commercial machines come with grinders that can be programmed for different drink sizes. This ensures consistency in results each time. Super-automatic espresso machines go one step further by automating and programmable the entire process from brewing to dispensing. These types of machines typically get high marks in Lab tests due to their hands-off accessibility.

Manual or commercial Espresso Machine semi-automatic machines require more work from the barista but often the results are worth the effort. This model won an 2022 Good Housekeeping Coffee Award for its smart dosing feature that weighs and distributes the correct amount of ground coffee every time. It also comes with a low pressure pre-infusion system to ensure smooth extraction and a milk frothing wand that performed well in our tests for producing thick, rich steaming milk.

Temperature

When it comes to espresso temperature, it plays a significant impact on the flavor and quality of your coffee. If the temperature of your water is not at a suitable level, it could cause extraction to be impeded and even result in a bitter cup.

Luckily, the best espresso machines have tools that allow you to keep your water at the correct temperature. One method to achieve this is by utilizing PIDs, which monitors and adjusts the temperature of the water. Another method is using a double boiler system. One boiler can be used to heat steam and water for tea, while using the second boiler to heat water to brewing temperature.

Carles explains how these systems can make a difference for both large businesses and baristas who work from home. They can assist novices create the perfect espresso drink because they can keep a precise temperature and avoid several variables that can affect the flavor quality. It is also easier for baristas with more experience to dial in their espressos exactly how they want.

Pressure

The amount of pressure an espresso machine uses is another aspect 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 that is used, even though other factors remain constant.

In general, most commercial-grade machines utilize nine bars of pressure to create 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 sophisticated to handle the increased levels of pressure.

While some espresso machines advertise 15 or 18 bars of pressure on their machines Nine bars are generally considered to be the standard for making consistently excellent brews. These machines with higher pressures are generally more affordable and are 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 greater pressure a professional espresso machine is able to apply more pressure, the better it'll be at extracting flavor from your favorite coffee and espresso maker beans. It is worth investing in top-quality machines that can give the highest quality results.

Barista Skills

A barista must be able to handle orders quickly and accurately. This is especially crucial when there is a lot of activity in the coffee shop. A good understanding of customer service is also essential for building customer relationships and increasing sales for the shop. This includes recognizing frequent customers, working effectively to resolve issues, and remaining friendly and positive in challenging circumstances.

A strong ability to multitask is a must for baristas, since they may be required to take orders and operate the cash register and then communicate orders to coworkers and answer phone calls at one time. This ability allows customers to enjoy an enjoyable coffee shop experience by ensuring that orders are delivered quickly.

It is helpful for baristas to have knowledge of the various styles of drinks that can be prepared using an espresso machine. This can be learned by reading up on the different types of coffee, attempting them out in person, or watching videos on the internet. Many baristas find it beneficial to take classes on the topic, which are offered by a variety of organizations.
