How Does Machine Espresso Work?
Machine espresso utilizes precise pressure and mind-blowing filter technology to create the perfect cup of coffee. How exactly does it work?
Espresso is produced by pushing hot water under high pressure through finely ground coffee. The process is similar to making drip coffee, but the difference is in the pressure.
The Group Head
The group head is the portafilter that you insert when brewing espresso. It disperses water in the portafilter, and regulates the pressure of the extraction. There are a variety of types of group head each with its unique advantages and drawbacks. Some are designed to provide stability in temperature, while others are designed to handle pre-infusion. Others are made to control the lever. There are also some that contain a variety of features, like the E61 one, which is the most popular choice among baristas because of its ability to provide multiple benefits in one package.
As you can see in the photo above, the group head has several notches where you place your portafilter before twisting it with your hands to lock it in. A gasket made of rubber is positioned inside the notches to help create a seal when you insert your portafilter. The notches allow for precise placement of your portafilter. This is vital for an accurate extraction.
The group head not only lets you to place your portafilter easily, but it also maintains the same temperature. It does this by cycling hot water through the brew pan and Coffeee around the portafilter to ensure that it is always at the correct temperature for extraction. This is important, as just a few degrees could mean the difference between good and excellent espresso.
The Pump
In contrast to manual piston machines which rely on a lever that pressurize water, Rotary espresso machines rely on motorized pumps to deliver the nine atmospheric bars of pressure required for espresso extraction. This pressure is built up by pumping water through a heat exchanger and then through the ground coffee.
Pumps are typically less expensive than piston-driven machines, and they tend to last longer, however both types of machine can get damaged through overuse and lack of cleaning. Pumps are also more complicated mechanically, and can add to the price of even the simple models.
Some espresso machines employ steam pressure instead of a pump for brewing espresso. The drawback is that the boiler that produces steam also raises the temperature of water to boiling which can cause excessive extraction. They also have to constantly rebuild their pressure in between cups. This takes energy and time.
Many espresso machines use an rotary or a vibration pump. A vibration model uses a rotating disk to generate pressure, whereas a Rotary model pushes hot coffee through the ground at high speed. Both machines can make great espresso but rotary machines are more quiet, durable and less likely to fail.
The Boiler
The boiler is the component which heats the water to the optimal temperature to extract. The steam that is created gets to the portafilter which is the container that holds the espresso coffee grounds. It is then poured into the cup. The steam creates enough pressure to push the grounds of the coffee through. This results in a whipped-up the top of the espresso. This is one of the main characteristics of a great espresso.
There are three types of espresso makers, which differ in the kind of pump they use and the degree of heat that the coffee is. There are a variety of ways to control the brew and the size of the cup that can be produced by the machine.
The first espresso machines were steam types. They employed only one boiler to make both steam and brew however the pressure they were able to produce was not very high - two bars of atmospheric pressure, at most. The coffee tasted bitter and burned. This is why the Milanese producers Luigi Bezzerra and Desiderio Pavoni developed the modern espresso machine.
The most well-known espresso maker is a semi-automatic machine with an electric pump. When people think of espresso machines, they imagine these machines. If you have a semi-automatic machine you must grind the beans and then tamp them by hand. However, the pump is able to regulate the flow of water and Coffeee pressure. This is a great solution that combines human control with mechanized consistency.
The Filter
Espresso machines usually use a filter that separates the grounds of coffee from hot water. The filter is also an essential component of the machine's temperature control, since it stops overheating.
A filter also improves flavor as it allows for the beans to flower for a longer period of time. This lets the beans let their nuances out, and allows for a better extraction.
It is important to remember that even the finest filter can make a bad cup of coffee. The quality of the beans and the extraction process, are still crucial.
It's here that the magic takes place. This is the reason why espresso tastes so good. The grouphead, also called the brewhead, is where the portafilter (the device you put the coffee ground into) sits when you're making espresso.
Steam-driven espresso machines make use of hot water that is heated in an airtight container to produce steam. The steam then pushes hot water into the grounds of coffee at high pressure. They are less expensive and easier for the owner to maintain than pumps-driven models. They are however limited to create the ideal brewing conditions as they only operate with 1-1.5 bar of pressure. The ideal shot requires 9-10 bars.
In recent years, espresso machines powered by a compressed air pump have become increasingly popular. They utilize an air compressor to push hot water into the grounds and are more portable than steam-driven electric machines.
