How Does Machine Espresso Work?
Machine espresso makes use of precise pressure and incredible filter technology to produce the coffee espresso machines we love. How does it work exactly?
To make an espresso, hot water is forced under high pressure through finely ground coffee. The process is similar to that of making drip coffee. However the pressure is the major difference.
The Head of the Group
The group head is the portafilter that you place in the espresso maker when making it. It is responsible for dispersing the water into the portafilter and controlling the pressure of the resulting extraction. There are several different types of group head, each with their unique advantages and drawbacks. Some are designed for stability of temperature while others are specifically designed to handle pre-infusion. Some are designed to control the lever. Some come with a range of features, like the E61, which is considered the most popular choice among baristas because of its ability to offer multiple perks in a single package.
As you can see from the picture above, the group head is fitted with several notches. It is possible to place your portafilter inside these notches, and then twist the head to secure it. There is also a gasket of rubber in the notches, which helps create an airtight seal when you insert your portafilter into the machine. The notches allow for precise placement of the portafilter. This is vital for a consistent extraction.
Apart from allowing you easily connect your portafilter, the group head is also responsible to ensure that the temperature remains even. This is accomplished by cycling hot water around the portafilter, and through the brew-basket to ensure that the temperature is at the right level for extraction. This is important, as just a few degrees could make the difference between a good and great espresso.
The Pump
In contrast to manual piston machines which rely on a lever to pressurize water, rotary espresso machines rely on motorized pumps to provide the nine atmospheric bars of pressure needed to extract espresso. This pressure is built up by pumping water through a heat-exchanger and then through the ground coffee.
Pumps tend to be 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. They also make mechanically complex, which can result in a high price tag on even the most basic models.
Some espresso machines employ steam pressure instead of a pump to brew home espresso machine. The drawback is that the boiler that produces steam also increases the temperature of the water to boiling, which can lead to excessive extraction. Additionally, these machines frequently have to rebuild their pressure between cups, which requires time and energy.
A majority of espresso machine with milk frother machines use a vibration or rotary pump, which is a vibration model using a vibrating disc to create pressure, and rotating models that push hot water through the grounds at high speed. Both models can make excellent espresso, but Rotary machines are quieter and more durable than vibration pumps.
The Boiler
The boiler is the component that heats water to an ideal temperature to extract. The resulting steam reaches the portafilter containing ground espresso beans and is then pumped into the cup. During this process, the steam creates pressure and pushes through the coffee grounds. This creates a foam on top of the espresso. This is a hallmark of a good best budget espresso machine.
There are three kinds of espresso machines, each having different pumps and the temperature of the brew. There are various ways to control the amount of brew, as well as the size of the cup that can be produced by the machine.
The first espresso machines were steam-types. They utilized only one boiler to make both brew and steam, but the pressure they could produce was very low - just two bars of atmospheric pressure, at most. The coffee tasted bitter and burned. The modern travel espresso maker machine was invented by the Milanese makers Luigi Bezzerra & Desiderio Pavoni.
The most common espresso maker is a semi-automatic device that has an electric pump. When people think of espresso machines, they envision these machines. With a semi-automatic espresso machine, you need to grind the beans and then tamp them by hand. However, the pump provides regulated water flow and pressure. This is a great compromise between the human touch and mechanized accuracy.
The Filter
Espresso machines typically use a filter that separates the grounds of the coffee from hot water. The filter is also a vital element of the machine's temperature control, since it stops overheating.
A filter can also help with flavor as it allows for the beans to flower for a longer period of time. This allows the beans to release their flavors, and allows for better extraction.
However, it is important to remember that even a high-quality filter can result in a poor cup of coffee, since the quality of the beans and extraction is still crucial.
This is where the magic happens, and it's what makes espresso taste good. The grouphead (also known as the brewhead) is where you place the portafilter, the device used to place the coffee grounds into, when making espresso.
In the steam-driven espresso machine hot water is heated in an airtight tank to create steam, which then pushes the hot water through the grounds at a high pressure. These machines are less expensive and are easier for the user to maintain than pumps-driven models. They are however limited in their ability to create the perfect conditions for brewing, as they operate with 1-1.5 bar of pressure. The ideal shot requires 9-10 bars.
In recent years, espresso machines powered by compressed air-pump have become increasingly popular. They use an air compressor to push hot water through grounds and are much more portable than steam-driven electric machines.
