How Does Machine Espresso Work?
Machine espresso employs precise pressure and incredible filter technology to produce the coffee we love. What exactly does it work?
In order to make espresso hot water is pushed under 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
As the name implies, the group head is where you place your portafilter while brewing espresso. It disperses the water into the portafilter, and regulates the pressure of the extraction. There are a variety of group heads each with distinct advantages and disadvantages. Some focus on temperature stability, others on pre-infusion capabilities, while others are designed to control the lever. There are even some that have a combination of features, such as the E61, which is considered to be the most popular among baristas due to its capacity to provide multiple benefits in a single package.
As you can see in the above photo the group head comes with numerous notches that you can put your portafilter, then twist it by hand to secure it. A rubber gasket is located in the notches to make a seal when you insert your portafilter. The notches on the head permit an exact placement of the portafilter, which is necessary for an efficient extraction.
In addition to allowing you to easily connect your portafilter, the group head is responsible for maintaining an even temperature. This is accomplished by cycling hot water around the portafilter and through the brew-basket, making sure that the temperature is constant to extract the coffee and espresso maker. It is crucial to keep in mind that even a few degree difference can make the difference between a decent and a excellent espresso.
The Pump
The motorized pumps in rotary espresso machines supply the nine atmospheric bars of pressure required for discount espresso machines extraction. This differs from manual piston machines that rely on a lever. This pressure builds up by drawing tap water from a reservoir and pumping it through a heat exchanger before being pumped through the ground coffee in the group head.
Pumps are typically cheaper and last longer than piston-driven machines. However, both kinds of machines can deteriorate due to excessive use and poor cleaning. They also create mechanical complexity, which can result in costly prices for even the simplest models.
Some espresso machines employ steam pressure instead of a pump for brewing espresso. The drawback of this is that the same boiler that produces steam also increases the temperature of the water to the point of boiling, which can lead to excessive extraction. In addition these machines typically have to rebuild their pressure between cups, which takes time and energy.
Many espresso machines use a rotary or vibration pump. A vibration model uses the vibrating disk to create pressure, whereas a circular model pushes hot liquid through the ground at a rapid speed. Both machines can produce excellent espresso, however rotary machines are more stable, quieter and less likely to break down.
The Boiler
The boiler is the part that heats the water to the ideal temperature for extraction. The resultant steam then reaches the portafilter that contains the ground espresso coffee and is then pumped down into the cup. The steam causes enough pressure to push the grounds of coffee through. This results in a layer of crema on top. This is one of the hallmarks of a great espresso.
There are three types of espresso makers, which differ in the type of pump they employ and the degree of heat that the brew is. There are various ways that the brew can be controlled and the size of the cup that the machine is capable of making.
The first espresso machines were steam types. They used a single boiler to make both steam and brew however the pressure they were able to produce was very low - just two bars of atmospheric pressure, at most. This resulted in the coffee tasting bitter and burnt. The modern espresso machine uk machine was created by the Milanese makers Luigi Bezzerra & Desiderio Pavoni.
The most well-known espresso machine is a semiautomatic one with an electric pump. These are the images people have when they think of an espresso maker. Semi-automatic machines require you to grind and tamp the beans yourself, but the pump regulates the flow of water and pressure. This is a great solution that combines human control with mechanized consistency.
The Filter
Espresso machines usually use a filter that separates the grounds of the coffee from hot water. The filter is also a vital part of the temperature control system as it prevents the machine from overheating.
Filters also aid in flavor as it allows for the beans to flower for a longer period of time. This allows the beans to release their flavors and provides an opportunity to improve 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 is still crucial.
This is where the magic happens. It's what makes espresso taste good. The grouphead, sometimes called the brew head, is where the portafilter (the thingy you put the coffee ground into) is placed when making espresso.
In a steam-driven professional espresso maker machine hot water is heated in an airtight tank to create steam. Steam then pushes the hot water through the grounds at high end espresso machine pressure. They are less expensive and easier for the user to maintain than pumps-driven models. They are however limited in their ability for creating the ideal conditions for brewing since they only 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 become more popular. They use an air compressor to push hot water through the grounds and are much more portable than electric steam-driven machines.
