How Does Machine Espresso Work?
The machine espresso utilizes precision pressure, and filter technology that is mind-blowing to make the coffee you love. How exactly does it work?
uk espresso machine is produced by pushing hot water under pressure through finely-ground coffee. The process is similar to making drip coffee but the major difference is in the pressure.
The Group Head
As the name suggests the group head is the place you place your portafilter when brewing espresso. It is responsible for dispersing water into the portafilter, and controlling the pressure that results from the extraction. There are various kinds of group heads, each with their distinct advantages and disadvantages. Some focus on temperature stability, while others on pre-infusion capabilities, while others are designed to control the lever. Some have a combination, like the E61. This is a preferred choice for baristas because it offers multiple benefits in one package.
As you can see in the photo above the head of the group is fitted with several notches. It is possible to place your portafilter inside these notches, and then twist the head to secure it. A gasket made of rubber is positioned within the notches to make a seal when you insert your portafilter. The notches on the head permit a precise positioning of the portafilter which is crucial to ensure an even extraction.
The group head is not just able to allow you to insert your portafilter easily, but it also maintains the same temperature. This is done by cycling hot water around the portafilter, and through the brew-basket, ensuring that the temperature is constant for extraction. It is important to note that even a slight difference can make the difference between a good and great 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 supply the nine atmospheric bars of pressure required for barista espresso coffee machine extraction. The pressure is created by pumping water through a heat-exchanger and then through the ground coffee.
Pumps tend to be cheaper and last longer than piston-driven machines. However, both kinds of machines can deteriorate due to excessive use and inadequate cleaning. Pumps are also more complicated mechanically, which can increase the price of even the simplest models.
Some espresso machines can eliminate the pump entirely and use steam pressure to brew espresso. The downside is that the same boiler that produces steam also raises the temperature of the water until it reaches boiling, which can lead to excessive extraction. They also have to continuously rebuild their pressure between cups. This takes energy and time.
Many espresso machines use the rotary or vibration pump. A vibration model utilizes a rotating disk to generate pressure, whereas the Rotary model pushes hot coffee through the ground at a high speed. Both machines can make great espresso, however rotary machines are quieter, more durable and less likely to fail.
The Boiler
The boiler is the one that will heat the water to the perfect temperature for extraction. The steam produced reaches the portafilter, which holds the espresso grounds. It is then poured into the cup. During this process, the steam creates pressure to push through the grounds of the coffee. This results in a crema on the top of the espresso. This is a hallmark of a good professional espresso maker.
There are three distinct types of espresso machines, each having distinct pumps and the temperature of the brew. There are a variety of ways to control the strength of the brew and the size of cup that can be made by the machine.
The first espresso machines were steam-types. The earliest espresso machine black friday machines were steam types. This resulted in the coffee tasting burnt and bitter. This is why the Milanese makers Luigi Bezzerra and Desiderio Pavoni developed the modern espresso machine.
The most popular espresso machine is a semiautomatic that has an electric pump. These are the things people think of when they think of an espresso maker barista maker. Semi-automatic machines require you to grind and tamp the beans by yourself The pump, however, regulates the flow of water and pressure. This is an excellent compromise between human touch and the mechanized quality.
The Filter
Typically, espresso machines have filters to separate the grounds of coffee when they pass through the hot water. The filter is also a vital component of the machine's temp control, as it prevents overheating.
It also helps with flavor, since a filter lets you enjoy a longer bloom time. This lets the beans release their flavor and improves extraction.
However, it is important to keep in mind that even a good filter can result in a poor cup of coffee, because the quality of the beans and extraction is crucial.
This is where the magic happens. It's what makes espresso taste good. The grouphead, often referred to as the brew head, is the place where the portafilter (the thing you put the ground coffee into) is located when you're making espresso.
Steam-driven espresso machines use hot water that is heated inside an airtight vessel to create steam. The steam then pushes hot water through grounds of the coffee under pressure. These kinds of machines tend to be less expensive and easier to maintain than pump-driven models. They are however limited in their ability for creating the ideal conditions for brewing, as they operate with 1-1.5 bar of pressure. The perfect shot requires 9-10 bars.
In recent years, compressed air pump-driven espresso machines have been gaining popularity. They utilize an air compressor to push hot water through grounds and are significantly more portable than steam-driven electric machines.
