How to Build a Professional Espresso Machine

This is a great choice for coffee shops and cafes which want to draw customers who are enthusiastic about espresso and barista skills. It's the official machine of the World Barista Championships and it really shows.

The barista can refill the water reservoir during their shift. The machine has a tea hot water tap and cool-touch steam wands.

Water

A commercial espresso machine has to produce a high volume of espresso based drinks efficiently. They are typically made of stainless steel, which is tough and resistant to breakages and scratches. These espresso machines are easier to maintain and keep clean.

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

When choosing your water, make sure to test it and treat it correctly to ensure the best home espresso machine results. For example, distilled water can be restored by adding a tiny amount of minerals back to it. It can improve the taste and negate its erosive characteristics, but could also cause damage to certain machines. The remineralized wate can make the boiler sensor believe that the machine is full even though it's not. This could cause overheating and even damage to the machine.

Grinder

The grinder is a key element in an espresso machine that works. It grinds a raw bean and turns it into finely ground coffee that can be properly placed into the filter basket to produce an excellent extraction.

Professional commercial machines come with grinders that are programmed to work with different sizes of drink. This ensures consistent results every time. Super-automatic retro espresso machine machines take this one step further by automating and programmable the whole process from brewing to dispensing. These machines are often praised by Lab tests for being easy to use.

A manual or semi-automatic espresso machine requires more involvement from the barista but the quality of the final result is often worth it. This model won the Good Housekeeping Coffee Award in 2022 for its intelligent dosing system that measures and dispenses the right amount of coffee each time. It also comes with an infusion with low pressure for balanced extraction, and a milk frother that made dense, thick steamed milk during our tests.

Temperature

The temperature is a crucial factor in espresso. If the water isn't in its ideal temperature, it can hinder extraction and even lead to the coffee being bitter.

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 temperature of the water. Another option is using a double boiler system. You can use one boiler to heat steam and water for tea, while using the second for heating water to brewing temperature.

Carles explains how these systems can make a difference for large corporations as well as home-based baristas. They make it easier for newbies to dial in the perfect espresso drink because they maintain an exact temperature and eliminate a lot of the variables that can throw off the flavor profile. It can also make it easier for experienced baristas to make their shots exactly as they would like them.

Pressure

The pressure that the espresso machine makes use of can affect the quality of the coffee it makes. Many espresso drinkers notice that their beverages taste different based on the pressure that is used, even though all other factors remain the same.

The majority of commercial machines utilize 9 bars of pressure in order to make espresso. They also tend to be pump-driven, not steam-driven. While higher-pressure machines exist, they often require a more sophisticated group head design that can handle the increased pressure levels.

While you may find espresso machines espresso that advertise 15 or even 18 bars of pressure, nine bars are generally considered the gold standard for consistently excellent espressos. These higher-pressure machines are typically more affordable and are designed for home use.

To put 9 bars of pressure in perspective, it's over four times the amount that's exerted by the air inside your car tire. The greater pressure a professional espresso maker can apply, the better at separating flavor from your favorite coffee beans. It's worthwhile to invest in high-end machines that can give the best home espresso machine results.

This ability allows customers to enjoy an enjoyable coffee shop experience by ensuring that orders are served quickly.

It is vital for a barista's knowledge in order to make various types of coffee using an espresso machine. You can find out about the various kinds of espresso by studying them, experimenting with them in person, or watching online videos.
