How Does Machine Espresso Work?
Machine espresso makes use of precise pressure and mind-blowing filter technology to make the perfect cup of coffee. What exactly is it that makes it work?
Espresso is made by forcing hot water under pressure through finely ground coffee. The process is similar to making drip coffee. However, the pressure is the major difference.
The Group Head
The group head is the portafilter you place in the espresso maker when making it. It disperses water into the portafilter, and then controls the pressure of the extraction. There are a variety of types of group heads, each with their unique advantages and disadvantages. Some are specifically designed for stability in temperature, while others are designed to handle pre-infusion. Others are built to control the lever. Some come with a combination of both, such as the E61. This is a popular choice among baristas as it provides a variety of advantages in a single package.
As you can see in the image above The group head features several notches to put your portafilter, then twist it manually to secure it. A rubber gasket is located in the notches to create a seal when you insert your portafilter. The notches on the head permit an exact position of the portafilter which is essential for an even extraction.
The group head not only allows the portafilter to be inserted easily however it also keeps the temperature at a constant level. It does this by circulating hot water through the brew basket and around the portafilter, making sure that it's always at the correct temperature for extraction. It is important to remember that even a few degree differences can make the distinction between a decent and a excellent espresso.
The Pump
In contrast to piston machines that are manually operated, which rely on a lever to pressurize water, the rotary espresso machines use motorized pumps to supply the nine atmospheric bars of pressure that are required to extract espresso. The pressure is created by pumping water through a heat-exchanger and then through the ground coffee.
Pumps are typically less expensive and last for longer than piston-driven machines. However, both kinds of machines can deteriorate due to overuse and poor cleaning. They also add mechanical complexity which can result in an expensive price for even the most basic models.
Certain espresso machines can eliminate the pump entirely and employ steam pressure to create espresso. The disadvantage of this is that the same boiler that produces steam also raises the temperature of the water until it reaches boiling and can result in over-extraction. The machines also need to constantly rebuild their pressure between cups. This requires energy and time.
Many espresso machines make use of a rotary or vibration pump. A vibration model employs a vibrating disk to generate pressure, while the Rotary model pushes hot coffee through the ground at a high speed. Both machines can make excellent espresso however rotary machines tend to be more quiet, durable and less likely to fail.
The Boiler
The boiler makes the water warm to the ideal temperature to extract. The resulting steam reaches the portafilter, which contains ground espresso machines home beans and is then funneled down into the cup. During this process, the steam creates pressure to push through the grounds of the coffee. This creates a crema on top of the espresso. This is a hallmark of a great espresso coffee maker.
There are three types of espresso makers, and they differ in the type of pump they use and how hot the coffee is. There are different ways that the brew may be controlled and the dimensions of the cup the machine can produce.
The first espresso machines were steam-types. They utilized a single boiler to make both steam and brew, but the pressure they could produce was not very high - two bars of atmospheric pressure maximum. This resulted in the coffee tasting burnt and bitter. This is the reason why Milanese manufacturers Luigi Bezzerra and Desiderio Pavoni developed the modern espresso home machine machine.
The most popular espresso maker is a semi-automatic machine with an electric pump. When people think of espresso machines, they imagine these machines. With a semi-automatic machine, you must grind the beans and tamp them by hand, but the pump regulates the flow of water and pressure. This is an excellent compromise between human touch and mechanized accuracy.
The Filter
Typically, espresso machines use filters that separate the coffee grounds as they pass through the hot water. The filter is also an important part of the temperature control system, as it prevents the machine from overheating.
It also aids in flavor, as a filter allows for a longer bloom time. This helps the beans release their nuances and gives an opportunity for a better extraction.
It is important to keep in mind that even the finest filter can result in a bad cup of coffee. The quality of the beans, and the extraction process, are still crucial.
This is where the magic happens, and it's what makes an espresso really taste great. The grouphead, sometimes referred to as the brew head, is the place where the portafilter (the thingy you put the coffee grounds into) sits when you're making espresso.
Steam-driven espresso machines make use of hot water that is heated inside an airtight container to create steam. The steam then pushes hot water into the coffee grounds under high pressure. These types of machines are usually less expensive and simpler to maintain than pumps-driven models. However, they are not as efficient in their ability to produce the perfect conditions for brewing, since they operate at 1-1.5 bars of pressure. However, the perfect shot requires 9-10 bars.
In recent years, compressed air-driven espresso machines have been gaining popularity. They use an air compressor to push hot water across the ground. They are also more mobile than steam-driven electric espresso coffee makers machines.
