How Does Machine Espresso Work?
Machine espresso employs precise pressure and amazing filter technology to make the delicious coffee espresso machine we enjoy. What exactly does it work?
Espresso is made by pushing hot water at high pressure through finely ground coffee. The process is similar to making drip coffee. However it is the pressure that makes the main difference.
The Group Head
The group head is the portafilter that you insert when brewing espresso. It distributes water into the portafilter, and regulates the pressure of the extraction. There are several different types of group heads, each with their particular advantages and drawbacks. Some are focused on temperature stability, some on pre-infusion features, and others are designed to control the lever. Some include a combination such as 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 features many notches in which you can place your portafilter before twisting it manually to secure it. A gasket made of rubber is positioned within the notches to create a seal when you insert your portafilter. The notches on the head allow for an exact placement of the portafilter, which is crucial to ensure an even extraction.
The group head is not just able to allow the portafilter to be inserted easily, but it also maintains an even temperature. This is done by cycling hot water around the portafilter and through the brew-basket, making sure that the temperature is at the right level to extract the coffee. This is important, as even a small difference in temperature can be the difference between a 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 that provide the nine atmospheric bars of pressure needed for espresso extraction. The pressure is built by pumping water through a heat exchanger and then through the ground coffee.
Pumps are generally less expensive than piston-driven machines, and tend to last longer. However, both types of machines could get damaged through overuse and lack of cleaning. Pumps are also more complicated mechanically, and can add to prices of even most basic models.
Some espresso machines use steam pressure instead of a pump to make espresso and filter coffee machine. This can cause over-extraction because the boiler that makes steam also causes the water bean to cup espresso machines boil. Additionally the machines often have to restore their pressure between cups, which requires time and energy.
A large majority of espresso machines employ an rotary or a vibration pump. A vibration model uses a vibrating disk to generate pressure, while a rotary model pushes hot water through the best ground coffee for espresso machine at a high speed. Both machines can make excellent espresso, however rotary machines are quieter, more durable and less likely to break down.
The Boiler
The boiler is the one that heats the water to the ideal temperature for extraction. The resultant steam then reaches the portafilter, which contains the ground espresso and is then pumped down into the cup. During this process the steam creates enough pressure to push the grounds of the coffee through. This creates a foam on the top of the espresso. This is the hallmark of a good espresso.
There are three kinds of espresso makers, which differ in the type of pump they use and the degree of heat that the espresso is. There are various ways to control the brew as well as the size of the cup that can be produced by the machine.
The first espresso machines were steam-type. The earliest espresso machines were steam types. This led to the coffee tasting bitter and burnt. This is why the Milanese makers Luigi Bezzerra and Desiderio Pavoni created the modern espresso machine.
The most common espresso machine is a semiautomatic model with an electric pump. These are the images people have when they imagine an espresso machine with grinder machine. With a semi-automatic espresso machine, you have to grind the beans and tamp them by hand. The pump is able to regulate the flow of water and pressure. This is a great compromise between the human touch and the mechanised quality.
The Filter
Espresso machines usually use filters that separate the grounds of the coffee from the hot water. The filter is also a vital element of the machine's temperature control, as it prevents overheating.
It also helps with flavor, since a filter allows for a more prolonged bloom phase. This allows the beans to release their flavors, and allows for a better extraction.
However it is crucial to remember that even a high-quality filter could result in a bad cup of coffee, since the quality of the beans and extraction are important.
This is where the magic happens, it's the thing that makes an espresso really taste great. The grouphead, sometimes referred to as the brew head, is where the portafilter (the thingy you put the coffee ground into) is placed when you're making espresso.
In a 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 types of machines are usually less expensive and simpler to maintain than pump-driven models. However, they are limited in their ability to create the ideal conditions for brewing since they are only operating at 1-1.5 bars of pressure. While the perfect shot requires 9-10 bars.
In recent years, compressed-air-pump-driven espresso maker barista machines have been gaining popularity. They use an air compressor to push hot water through grounds and are significantly more portable than electric steam-driven machines.
