How Does Machine Espresso Work?
Machine espresso utilizes precise pressure and mind-blowing filter technology to create the coffee we love. But how exactly does it work?
To make espresso hot water is forced 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 put in when making espresso. It is responsible for dispersing water into the portafilter before controlling the pressure of the extraction. There are many different kinds of group heads, each with their unique advantages and drawbacks. Some focus on temperature stability, some on pre-infusion capabilities, and still others are designed to control the lever. Some include a combination such as the E61. This is a very popular choice for baristas due to the fact that it has multiple benefits in a single package.
As you can see in the photo above, the group head has several notches to place your portafilter before twisting it by hand to secure it. A gasket made of rubber is placed inside the notches to help create a seal while you insert your portafilter. The notches permit precise placement of your portafilter. This is essential for an even extraction.
In addition to allowing you to easily insert your portafilter, the group head is responsible to ensure that the temperature remains even. It does this by circulating hot water through the brew pan and around the portafilter, ensuring that it is always at the correct temperature for extraction. It is important to remember that even a small difference can make the difference between a good and a excellent espresso.
The Pump
In contrast to piston machines that are manually operated, which rely on a lever that pressurize water, Rotary espresso machines rely on motorized pumps to provide the nine atmospheric bars of pressure that are required to extract espresso. This pressure is generated by pumping water through a heat-exchanger and then through the ground coffee.
Pumps tend to be cheaper than piston-driven machines, and they tend to last longer, however both types of machine can degrade with overuse and insufficient cleaning. They also add mechanical complexity which can result in the cost of even the most basic models.
Some buy espresso machines machines employ steam pressure instead of a pump for brewing espresso. The drawback is that the same boiler that produces steam also increases the temperature of water until it reaches boiling which can cause over-extraction. Additionally these machines typically have to rebuild their pressure between cups, which requires time and energy.
Many espresso machines make use of the rotary or vibration pump, with a vibration model using a vibrating disc to generate the pressure, and the rotary model pushing hot water through the grounds under high speed. Both machines can make great retro espresso maker, but rotary machines are more quiet, durable and less likely to break.
The Boiler
The boiler is the component which heats the water to the optimal temperature for extraction. The steam that is produced gets to the portafilter which is the container that holds the espresso coffee grounds. The steam is then channeled into the cup. The steam causes pressure to push through the coffee grounds. This creates a crema on the top of the espresso. This is one of the main characteristics of a great espresso.
There are three different types of retro espresso machine machines, each with different types of pumps and brew temperature. There are a variety of ways that the brew may be controlled and the size of the cup that the machine is capable of making.
The first espresso machines were steam-types. They had a single boiler to make both steam and brew, but the pressure they could produce was very low - just two bars of atmospheric pressure, at most. This resulted in the coffee tasting bitter and burnt. This is why the Milanese producers Luigi Bezzerra and Desiderio Pavoni invented the modern espresso machine.
The most common espresso machine is a semiautomatic model with an electric pump. These are the things people think of when they imagine an espresso makers machine. With a semi-automatic machine, you have to grind the beans and tamp them by hand. The pump controls the flow of water and pressure. This is a great compromise between the human touch and the mechanised accuracy.
The Filter
Typically, espresso machines use filters that separate the grounds of coffee when they pass through the hot water. The filter is also an essential component of the machine's temp control, as it helps prevent overheating.
Filters also aid in flavor since it allows for the beans to flower for a longer period of time. This helps the beans release their flavors and provides an opportunity for 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, are still very important.
This is where the magic happens, it's what makes an espresso really taste good. The grouphead (also known as the brewhead) is where you place the portafilter, the device that you put the coffee grounds in, when making espresso.
Steam-driven best home espresso machine machines use hot water that is heated inside an airtight container to produce steam. The steam then pushes hot water through the grounds of the coffee under pressure. These types of machines tend to be less expensive and simpler to maintain than pumps-driven models. However, they are limited in their ability to create 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 years, espresso machines driven by a compressed air pump have become increasingly popular. They utilize an air compressor to force hot water into the ground and are more mobile than electric steam-driven espresso machines.
