How Does Machine Espresso Work?
Machine espresso uses precision pressure and incredible filter technology to produce the perfect cup of coffee. What exactly is it?
To make espresso hot water is forced under high pressure through finely ground coffee. The process is similar to making drip coffee, but the key difference is in the pressure.
The Group Head
As the name implies, the group head is where you put your portafilter in when making espresso. It disperses the water into the portafilter, and regulates the pressure of the extraction. There are a variety of types of group head, each with their distinct advantages and disadvantages. Some are designed for the stability of temperature while some are built bean to cup espresso machine handle pre-infusion. Others are made to control the lever. There are also some that come with a range of features, like the E61 one, which is to be the most popular among baristas for its ability to offer multiple perks in a single package.
As you can see from the picture above the group head has a number of notches. It is possible to place your portafilter inside these notches, and then twist the head to secure it. There is also a gasket made from rubber that resides inside the notches to help create an airtight seal when you insert your portafilter into the machine. The notches permit the precise placement of the portafilter. This is vital for an accurate extraction.
The group head is not just able to allow you to place your portafilter easily however it also keeps the same temperature. It does this by circulating hot water through the brew container and around the portafilter, ensuring that it is always at the right temperature to extract. This is crucial, since just a few degrees could make the difference between a good and excellent espresso.
The Pump
The motorized pumps in espresso machines rotary provide nine atmospheric bar pressure needed for espresso extraction. This differs from manually operated piston machines that employ levers. The pressure is created by drawing tap water from a reservoir, and pumping it through a heat exchanger prior to being pushed through the ground coffee inside the group head.
Pumps are typically less expensive than piston-driven models, and they tend to last longer, however both types of machines may get damaged through overuse and lack of cleaning. Pumps are also more complex mechanically, and can add to prices of even simpler models.
Certain espresso machines utilize steam pressure instead of a pump to make espresso. This can lead to over-extraction as the dual boiler espresso machine that produces steam also warms the water to boil. Additionally these machines are often required to restore their pressure between cups, which takes time and energy.
Many espresso machines make use of the rotary or vibration pump. A vibration model utilizes the vibrating disk to create pressure, whereas the rotary model pushes hot water through the ground at a fast speed. Both types of machines can make a great espresso, but rotary machines are quieter and more durable than vibration pumps.
The Boiler
The boiler is the one that heats the water to the ideal temperature to extract. The steam created gets to the portafilter which is a container for espresso grounds. It is then funneled into the cup. During this process the steam generates enough pressure to push the grounds of the coffee through. This results in a layer crema on top. This is the hallmark of a great espresso.
There are three kinds of espresso coffee maker makers. They differ in the type of pump they use and how hot the espresso is. There are many ways to control the amount of brew, as well as the size of cup that can be made by the machine.
The first espresso machines were steam type. They employed only one boiler to make both steam and brew however the pressure they were able to produce was not very high - two bars of atmospheric pressure at the most. The coffee tasted bitter and burnt. This is why Milanese producers Luigi Bezzerra and Desiderio Pavoni invented the modern espresso machine.
The most commonly used espresso maker is a semi-automatic one with an electric pump. These are the images people have when they think of an espresso machine. Semi-automatic machines require you to grind and tamp the beans yourself, but the pump regulates the water flow and pressure. This is an excellent compromise between human touch and mechanized consistency.
The Filter
Espresso machines usually use a filter that separates the coffee grounds from the hot water. The filter is also a vital part of the temperature control system, as it keeps the machine from overheating.
It also aids in flavor, as it lets you enjoy a longer bloom time. This allows the beans to release their nuances, and allows for better extraction.
However, it is important to remember that even a top filter can make a terrible cup of coffee, since the quality of the beans and extraction is essential.
It's in this area that the magic takes place. This is the reason why espresso tastes so good. The grouphead (also called the brewhead) is where you place the portafilter, which is the thingy used to place the coffee grounds in, when making espresso maker for home.
Steam-driven espresso machines make use of hot water heated in an airtight vessel to create steam. The steam then pushes hot water into the grounds of coffee under high pressure. These kinds of machines are generally cheaper and easier to maintain than pumps-driven models. They are however limited in their ability to create the ideal brewing conditions as they only 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 the ground. They are also more mobile than electric steam-driven espresso machines.
