How to Build a Professional Espresso Machine
For coffee shops and cafes seeking to attract customers with an interest in espresso and barista skills this is a great option. It's the official machine for World Barista Championships and it really shows.
The barista is able to refill the reservoir of water throughout their shift. The machine is equipped with hot water for tea and steam wands that cool-touch.
Water
A commercial espresso machine needs to produce a large quantity of espresso-based drinks in an efficient manner. They are typically made of stainless steel, which is durable and resistant against breaks and scratches. Espresso machines are also easier to maintain and clean.
Finally, a high-quality machine will have a separate shut off valve for the water line, to prevent the formation of limescale. This will ensure that any repairs will be isolated to the affected components of the machine and won't impact the rest of your operation.
When you select your water ensure that you test it and treat it appropriately to get the best results. Remineralize distilled water by adding some minerals. home espresso machine can diminish its erosive properties and improve its flavor, but it may also damage machines. This is because the remineralized water will cause the boiler sensor to think that the machine is fully stocked, but it's not. This can cause the machine to overheat and be damaged.
Grinder
The grinder is an essential component of a successful espresso maker. It grinds a raw bean and turns it into finely ground coffee that is then placed into the filter basket for an excellent extraction.
Professional commercial grade machines include grinders that can be programmed to work with different sizes of drink. This guarantees constant results every time. Super-automatic espresso machines take this one step further, automating and programmable the whole process from brewing to grinding to dispensing. These machines are often praised during Lab tests for their ease to use.
Semi-automatic or manual machines demand more work from the barista but often the results are worth it. This model won the Good Housekeeping Coffee Award in 2022 for its clever dosing system, which measures and distributes the right amount of coffee every time. It also has a low-pressure pre-infusion mechanism for smooth extraction and a milk frothing wand that did well in our tests for producing thick, rich steaming milk.
Temperature
The temperature is a crucial element in espresso. If the water isn't at an ideal temperature, it may cause a delay in extraction, and could cause bitter coffee.
Luckily, the best espresso machines come with tools that enable you to keep your water at the right temperature. One method for doing this is by using PIDs that monitor and adjusts the temperature of the water. Double boiler systems are another way to do this. This lets you use a single boiler to tea and steam and the other one to heat water to brew temperatures.
Carles says that these kinds of systems can make the difference for large-scale businesses as well as home baristas. They can make it easier for beginners to determine the ideal espresso shot because they can maintain an exact temperature and eliminate some of the factors that can affect the flavor profile. It's also easier for baristas who have more experience to make their espressos exactly how they would like.
Pressure
The amount of pressure an espresso machine uses is another factor that influences the quality of the coffee it makes. Many espresso drinkers have noticed that their drinks taste different depending on the amount of pressure that is used, even though all other elements remain the same.
The majority of commercial machines utilize 9 bars of pressure to make espresso. They also tend to be pump-driven instead of steam-driven. Although high-pressure machines are offered but they require a group head that is more sophisticated to handle the increased levels of pressure.
While you may find espresso machines that advertise 15 or even 18 bars of pressure, nine bars are generally considered the gold standard for creating consistently excellent brews. These machines with higher pressure are generally less expensive and are intended for home use.
In comparison, 9 bar of pressure is four times more than the pressure exerted by your car tire. The more pressure a professional espresso machine can apply to the coffee, the better it will be at extracting flavor from your favorite coffee beans. It is worth investing in top-quality machines that can produce the best results.
Barista Skills
A barista should be able to take orders and handle them quickly and precisely. This is particularly important when there is a lot of activity in the coffee shop. Being able to provide excellent customer service is also crucial for establishing customer relationships and increasing business for the shop. This includes acknowledging regular customers, working effectively to resolve issues, and being positive and helpful even in challenging circumstances.
Being able to multitask is a must for a barista, as they might be required to take orders and operate the cash counter and communicate orders to colleagues and take phone calls simultaneously. This skill allows them to keep orders moving quickly to the customer, and gives them a pleasant experience in the coffee shop.
It is crucial for baristas to be able to prepare various drinks using an espresso machine. This can be gained through reading up on the different kinds of coffee, testing them in person, and watching videos on the internet. Many baristas find it beneficial to attend classes provided by various organizations.
