How Does Machine Espresso Work?
Machine espresso utilizes precise pressure and mind-blowing filter technology to create the delicious coffee we enjoy. What exactly is it that makes it work?
espresso maker for home is produced by pushing hot water under high pressure through finely-ground coffee. The process is similar to making drip coffee. However, the pressure is the primary difference.
The Head of the Group
As the name suggests the group head is where you insert your portafilter when brewing espresso. It is responsible for dispersing water into the portafilter and then controlling the pressure that results from the extraction. There are many different types of group heads, each with its own advantages and drawbacks. Some focus on temperature stability, others on pre-infusion options, and others are designed to control the lever. Some are a combination, like the E61. This is a popular choice among baristas since it provides multiple benefits in a single package.
As you can see in the image above, the group head is equipped with several notches. You place your portafilter into these notches and twist the head to secure it. There is also a gasket of rubber that resides inside the notches, which helps create an airtight seal after inserting your portafilter into the machine. The notches allow for precise placement of your portafilter. This is essential for an accurate extraction.
The group head not only lets you to place your portafilter easily however it also keeps the temperature at a constant level. It does this by cycling hot water through the brew basket and around the portafilter, making sure that it is always at the right temperature to extract. This is important, as even a few degrees can be the difference between a good and great espresso coffee machines.
The Pump
In contrast to piston machines that are manually operated, that use a lever to pressurize water, rotating espresso machines rely upon motorized pumps to provide the nine atmospheric bars of pressure that are required to extract espresso. The pressure is built by pumping water through a heat exchanger and then through the ground coffee.
Pumps are generally less expensive and last for longer than piston-driven machines. However, both kinds of machines can degrade due to excessive use and insufficient cleaning. Pumps are also more complex mechanically, which could increase the cost of even the most basic models.
Certain cafe espresso machine machines utilize steam pressure instead of a pump for brewing espresso. The disadvantage of this is that the same boiler that produces steam also raises the temperature of the water until it reaches boiling, which can lead to over-extraction. They also have to constantly rebuild their pressure between cups. This takes energy and time.
Many espresso machines make use of an rotary or a vibration pump. A vibration model utilizes the vibrating disk to create pressure, while a circular model pushes hot liquid through the ground at high speed. Both machines can produce excellent espresso, but rotary machines are quieter, more durable and less likely to break.
The Boiler
The boiler is the component that heats water to the optimal temperature for extraction. The steam that is created is then directed to the portafilter, which contains the espresso coffee grounds. The steam is then channeled into the cup. The steam causes enough pressure to push the grounds of the coffee through. This results in a whipped-up top of the espresso. This is one of the main characteristics of a great espresso.
There are three kinds of espresso makers. They differ in the type of pump they use and how hot the coffee is. There are a variety of ways that the brew can be controlled, as well as the size of the cup the machine can make.
The earliest espresso machines were steam-based. The earliest espresso machines were steam-type machines. The coffee tasted bitter and burnt. This is why the Milanese producers Luigi Bezzerra and Desiderio Pavoni developed the modern espresso machine.
The most popular espresso maker is a semi-automatic device that has an electric pump. When people think of espresso machines, they think of these machines. If you have a semi-automatic machine you have to grind the beans and tamp them yourself but the pump provides regulated water flow and pressure. This is an excellent combination of human control and mechanised accuracy.
The Filter
Espresso machines typically have filters that separate the grounds of the coffee from the hot water. The filter is also a vital element of the temperature control system, since it helps prevent the machine from overheating.
A filter also helps with flavor since it allows for a longer flowering period. This allows beans to release their nuances and gives an opportunity for a better extraction.
It is important to remember that even the best espresso maker filter can result in a bad cup of coffee. The quality of the beans as well as the extraction, are still crucial.
This is where the magic happens, it's the thing that makes espresso taste great. The grouphead, sometimes called the brew head, is where the portafilter (the container you place the coffee grounds into) sits when you're making espresso.
Steam-driven espresso machines make use of hot water heated in an airtight container to create steam. The steam then pushes hot water into the grounds of coffee under high pressure. These kinds of machines are usually cheaper and easier to maintain than pump-driven models. They are however limited in their ability to create the ideal conditions for brewing, as they operate with 1-1.5 bar of pressure. The ideal shot requires 9-10 bars.
In recent years, compressed air-driven espresso machines have become more popular. They utilize an air compressor to push hot water into the grounds, and are far more portable than electric steam-driven machines.
