How to Build a Professional Espresso Machine
This is an excellent choice for coffee shops and cafes which want to draw customers who are enthralled by espresso and barista abilities. It's the official machine used for World Barista Championships, and it demonstrates.
It also has a reservoir for water so that the barista just needs to refill it throughout their shift. The machine comes with a hot water tap for tea and steam wands with cool-touch.
Water
A commercial espresso machine has to produce a large quantity of espresso-based drinks efficiently. The machines are typically made of stainless steel, which is durable and resistant to breaks and scratches. Espresso machines are also easier to maintain and clean.
A high-quality machine should have a separate shut-off valve for the water pipe to avoid the build-up of limescale. This will ensure that any repairs are isolated to the affected parts of the machine and won't impact the remainder of your operation.
When selecting your water, make sure to test it and treat it properly to ensure the best results. For instance, distilled water can be recycled by adding a small amount of minerals back to it. This can negate it's erosive properties and improve the taste, but it could also cause damage to certain machines. The remineralized water will make the boiler sensor think the machine is full and it isn't. This can lead to overheating and damage the machine.
Grinder
The grinder is an essential component of a successful espresso maker. The grinder turns an unground, raw coffee bean into a finely -ground coffee that can be properly tamped into the filter basket to ensure the best extraction.
Commercial-grade espresso machines usually have a built-in grinder which can be programmed to grind various drink sizes, ensuring that the results are consistent every time. Super-automatic machines go further and automate the entire process, from brewing to grinding and dispensing. These kinds of machines typically get high scores in Lab tests for their hands-off accessibility.
A manual or semi-automatic espresso machine requires more involvement from the barista, but the quality of the final result is usually worth it. This model was awarded the 2022 Good Housekeeping Coffee Award for its dosing technology that weighs and dispenses the right amount of ground coffee each time. It also has the ability to use a low pressure pre-infusion to ensure balanced extraction, and a milk frother that made rich, thick steamed-milk during our tests.
Temperature
When it is time to make espresso temperature, it plays an important role in the taste and quality of your shots. If the temperature of your water is not at a suitable level, it can cause extraction to be impeded and could result in an unpleasant cup.
Fortunately, espresso machines of high-end quality have tools that allow you to ensure that your water is at the correct temperature. One way to do this is with PIDs that monitor and adjusts the temperature of the water. Double boiler systems are a second method to accomplish this. small espresso machine can use one boiler to heat steam and water for tea, while using the second to heat water to brewing temperature.
Carles explains how these systems can be beneficial for both large-scale businesses as well as baristas who work from home. They can make it easier for newbies to make the perfect espresso because they are able to maintain an exact temperature and eliminate some of the factors that can alter the flavor profile. It is also simpler for baristas with more experience to dial in their espressos just the way they would like.
Pressure
The pressure that an espresso machine is using also affects the quality of coffee it produces. Many espresso drinkers have noticed that their drinks taste different based on the amount of pressure that is used, even though all other factors remain constant.
The majority of commercial machines utilize 9 bars of pressure in order to brew espresso. These machines are also likely to be pump-driven, not steam-driven. While higher-pressure machines exist but they usually require a more intricate group head design to manage the higher pressure levels.
While some espresso machines advertise 15 or 18 bars of pressure in their machines 9 bars are typically considered to be the gold standard when it comes to making consistently excellent espressos. These machines with higher pressure tend to be cheaper and designed for home use.
To put 9 bars of pressure into perspective, it's over four times the amount of pressure that's imposed by the air in your car tire. The greater the pressure that a professional espresso machine can put on and the more effective it will be at removing the flavor from your favorite coffee beans. It's worth investing in top-quality machines that produce the best results.
Barista Skills
A barista should be able to take orders from customers quickly and accurately. This is particularly crucial during busy periods at the coffee shop. A good understanding of customer service is essential to build customer relationships and increasing business for the shop. This includes acknowledging regular customers, working effectively to resolve problems and remaining friendly and positive in the most difficult of situations.
The ability to multitask is a must for baristas, since they may be required to take orders and operate the cash counter and then communicate orders to coworkers and handle phone calls at the same time. This ability helps keep orders moving quickly to the customer, and ensures that customers have an enjoyable time in the coffee shop.
It is crucial for a barista's knowledge to be able to prepare different types of drinks using an espresso machine. You can find out about the various types of espresso by studying about them, experimenting with the drinks in person and by watching online videos. Many baristas find it beneficial to attend classes provided by various organizations.
