How Does Machine Espresso Work?
The machine espresso uses precise pressure and filtering system that is awe-inspiring to create the coffee you enjoy. What exactly does it work?
To make espresso hot water is pushed under pressure through finely ground coffee. The process is similar to making drip coffee however the main difference lies in the pressure.
The Group Head
As the name implies the group head is where you put your portafilter in when brewing espresso. It disperses water into the portafilter, and then regulates the pressure of extraction. There are various kinds of group heads each with its particular advantages and disadvantages. Some are designed to provide stability of temperature while others are specifically designed to handle pre-infusion. Others are built to control the lever. There are even some that contain a variety of features, like the E61, which is the classic choice among many baristas because of its ability to offer multiple benefits in a single package.
As you can see from the photo above the group head is fitted with a variety of notches. You can place your portafilter in these notches and then twist the head to secure it. There is also a gasket made from rubber which is located inside the notches and helps create a seal when you insert your portafilter into the machine. The notches allow for the precise placement of the portafilter. This is crucial for an accurate extraction.
The group head not only lets the portafilter to be inserted easily however it also keeps the same temperature. This is accomplished by cycling hot water around the portafilter, and through the brew-basket, making sure the temperature is always right to extract the coffee. This is important, as even a few degrees can be the difference between a excellent and great espresso.
The Pump
In contrast to manual piston machines that use a lever to pressurize water, rotary espresso machines rely on motorized pumps to supply the nine atmospheric bars of pressure that are required for espresso extraction. The pressure builds by drawing tap water from a reservoir, and pumping it through a heat exchanger before being pushed through the ground coffee in the group head.
Pumps tend to be less expensive than piston-driven machines, and they tend to last longer. However, both types of machines can become damaged due to excessive use and poor cleaning. Pumps are also more complex mechanically, which could increase the cost of even simplest models.
Certain espresso machines remove the pump completely and make use of steam pressure to make espresso. This can result in over-extraction because the boiler that makes steam also heats the water until it comes to a boil. In addition these machines are often required to restore their pressure between cups, which takes time and energy.
A majority of espresso machines use a vibration or rotary pump, with a vibrating model using a vibrating disc to create pressure, and an rotary model that pushes hot water through the grounds at high speed. Both machines produce great espresso, but rotary machines are quieter, more durable and less likely to fail.
The Boiler
The boiler is the component that heats water to the optimal temperature for extraction. The resulting steam reaches the portafilter that contains the ground espresso coffee and gets funnelled down into the cup. During this process, steam creates pressure and pushes through the coffee grounds. This results in a layer crema that is then poured over. This is a sign of a good espresso.
There are three kinds of espresso makers, Click That Link,. They differ in the type of pump they use and the degree of heat that the espresso is. There are various ways that the brew may be controlled and the dimensions of the cup the machine can produce.
The earliest espresso machines were steam types. The first espresso machines were steam-type machines. The coffee tasted bitter and burned. The modern espresso machine was developed by the Milanese manufacturers 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 think of these machines. Semi-automatic machines require you to grind and tamp the beans yourself however the pump controls the flow of water and pressure. This is an excellent compromise between human control and mechanized accuracy.
The Filter
Espresso machines usually have filters that separate the grounds of coffee from hot water. The filter is also an important part of the temperature control system, since it helps prevent the machine from overheating.
A filter also improves flavor because it allows for a longer flowering phase. This allows the beans to release their flavors and provides the chance for better extraction.
However it is crucial to remember that even a top filter could result in a bad cup of coffee as the quality of the beans and extraction are vital.
It's in this area that the magic happens. This is what makes best home espresso machine taste so delicious. The grouphead (also called the brewhead) is where you place the portafilter, the thingy which you put the coffee grounds into, when making espresso.
Steam-driven espresso machines use hot water heated in an airtight container to make steam. The steam then moves hot water through the grounds of coffee under high pressure. These kinds of machines tend to be cheaper and easier to maintain than pumps-driven models. They are however limited to create the perfect conditions for brewing since they only operate with 1-1.5 bar of pressure. The ideal shot requires 9-10 bars.
In recent years, compressed-air-pump-driven espresso machines have been gaining popularity. They make use of an air compressor to force hot water through the ground and are more mobile than steam-driven electric espresso machines.
