How Does Machine Espresso Work?
Machine espresso employs precise pressure and incredible filter technology to produce the delicious coffee we enjoy. How exactly does it work?
Espresso is made by pushing hot water under high pressure through finely ground coffee. The process is similar to making drip coffee however the main difference lies in the pressure.
The Head of the Group
The group head is the portafilter that you insert when brewing espresso. It is responsible for dispersing the water into the portafilter, and controlling the pressure of the extraction. There are many different kinds of group heads each with its own advantages and drawbacks. Some are designed for temperature stability while others are designed to handle pre-infusion. Others are built to control the lever. There are also some that contain a variety of features, such as the E61, which is considered the most popular choice among baristas for its ability to provide multiple benefits in one package.
As you can see in the photo above, the group head is equipped with several notches. The portafilter is placed in these notches and then turn the head around to secure it. A gasket made of rubber is placed in the notches to make a seal when you insert your portafilter. The notches on the head allow for a precise position of the portafilter which is crucial for an efficient extraction.
The group head is not just able to allow you to place your portafilter easily however it also keeps the same temperature. It does this by cycling hot water through the brew pan and around the portafilter, making sure that it's always at the correct temperature for extraction. It is important to remember that even a small differences can make the distinction between a good and a great espresso machines home.
The Pump
The motorized pumps that are used in commercial espresso machine machines rotary provide nine atmospheric bars of pressure required to extract espresso. This is different from manual piston machines that use a lever. This pressure builds up by removing tap water from a reservoir, and pumping it through a heat exchanger prior to being pushed through the ground coffee inside the group head.
Pumps are generally more affordable and last longer than piston-driven machines. However, both types of machines can degrade because of excessive use and insufficient cleaning. Pumps are also more complex mechanically, and can add to prices of even simpler models.
Certain espresso machines utilize steam pressure instead of a pump to brew decent espresso machine. This can cause over-extraction because the boiler that makes steam also warms the water to boil. Additionally, these machines frequently have to restore their pressure between cups, which requires time and energy.
Many espresso machines make use of an rotary or vibrating pump, which is a vibration model using a rotating disc that generates the pressure and the rotary model pushing hot water through the grounds at high speed. Both machines can make great espresso, however rotary machines are quieter, more durable and less likely to break down.
The Boiler
The Dual boiler espresso Machine is the component which heats the water to the optimal temperature to extract. The resultant steam then reaches the portafilter that contains the ground espresso and is then pumped down into the cup. The steam generates enough pressure to push the coffee grounds through. This results in a layer of crema that is then poured over. This is the hallmark of a good espresso.
There are three different types of espresso machines, each with different pumps and brew temperature. There are also different ways in which the brew can be controlled and the size of the cup the maker can create.
The first espresso machines were steam-type. The first espresso machines were steam types. This led to the coffee tasting burnt and bitter. This is why Milanese manufacturers Luigi Bezzerra and Desiderio Pavoni developed the modern espresso machine.
The most well-known espresso machine is a semiautomatic with an electric pump. When people think of espresso machines, they imagine these machines. With 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 a perfect compromise between human control and mechanised consistency.
The Filter
Espresso machines usually use filters that separate the grounds of coffee from hot water. The filter is also an essential component of the machine's temperature control, since it helps to prevent overheating.
It also helps with flavor, as a filter allows for a more prolonged bloom time. This helps the beans to release their nuances and gives an opportunity to improve extraction.
It is important to keep in mind that even the finest filter can make a bad cup of coffee. The quality of the beans and the extraction process, are still very important.
This is where the magic happens. It's what makes an espresso really taste good. The grouphead (also called the brewhead) is where you place the portafilter, the device that you put the coffee grounds in, when making espresso.
Steam-driven espresso maker for home machines use hot water that is heated inside an airtight container to create steam. The steam then pushes hot water through coffee grounds under high pressure. These machines are cheaper and easier for the owner to maintain than pumps-driven models. However, they are limited in their ability to provide the ideal brewing conditions, since they are only operating at 1-1.5 bars of pressure, while the perfect shot requires 9-10 bars.
In recent times, espresso machines powered by compressed air-pump have become increasingly popular. They use an air-compressor to force hot water through the ground. They are also more mobile than steam-driven electric barista espresso coffee machine machines.
