How Does Machine Espresso Work?
Machine retro espresso machine makes use of precise pressure and amazing filter technology to make the coffee we love. What exactly is it?
Espresso is created by forcing hot water under high pressure through finely-ground coffee. The process is similar to making drip coffee, but the difference is in the pressure.
The Group Head
The group head is the portafilter you place in the espresso maker when making it. It disperses the water into the portafilter and controls the pressure of the extraction. There are many different kinds of group heads, each with their particular advantages and disadvantages. Some are designed to provide stability in temperature, while others are specifically designed to handle pre-infusion. Some are designed to control the lever. There are some that have a combination of features, like the E61, which is the classic choice among many baristas due to its capacity to offer multiple perks in one package.
As you can see in the picture above, the group head has a number of notches. You place your portafilter in these notches, then turn the head around to secure it. There is also a gasket made from rubber in the notches and helps to create the seal when you insert your portafilter into the machine. The notches allow for the precise placement of the portafilter. This is crucial to ensure an accurate extraction.
The group head not only lets the portafilter to be inserted easily but also maintains an even temperature. This is done by cycling hot water around the portafilter and through the brew-basket, making sure that the temperature is at the right level to extract the coffee. It is important to note that even a few degree difference can make the difference between a good and a great espresso.
The Pump
In contrast to manual piston machines that use a lever to pressurize water, rotating espresso machines rely upon motorized pumps to supply the nine atmospheric bars of pressure needed for italian espresso machines extraction. The pressure builds up by drawing tap water from a reservoir, and pumping it through a heat exchanger prior being pumped through the ground coffee in the group head.
Pumps tend to be less expensive than piston-driven models, and they tend to last longer, although both types of machines could degrade with overuse and insufficient cleaning. They also add mechanical complexity, which can result in the cost of even the most basic models.
Certain espresso machines do away with the pump entirely and utilize steam pressure to make espresso. The disadvantage of this is that the same boiler that produces steam also raises the temperature of water to boiling, which can lead to excessive extraction. The machines also need to continuously rebuild their pressure between cups. This requires energy and time.
Many espresso machines make use of an rotary or vibrating pump, with a vibration model that uses a vibrating disc to create pressure, and the rotary model pushing hot water through the grounds at high speed. Both machines can make excellent espresso, but rotary machines are more stable, quieter and less likely to break.
The Boiler
The boiler makes the water warm to a temperature that is ideal for extraction. The steam produced will eventually reach the portafilter, which holds the best espresso machine under 500 grounds. It is then poured into the cup. During this process the steam causes enough pressure to push the grounds of coffee through. This creates a crema on the top of the espresso. This is one of the hallmarks of a good espresso.
There are three kinds of espresso makers. They differ in the kind of pump they use and how hot the espresso is. There are a variety of ways in which the brew could be controlled, as well as the size of the cup the machine can make.
The first espresso machines were steam types. They had one boiler to make both steam and brew but the pressure they could produce was not very high - two bars of atmospheric pressure at most. The coffee tasted bitter and burned. The modern espresso coffee maker machine was invented by the Milanese producers Luigi Bezzerra & Desiderio Pavoni.
The most commonly used espresso machine is a semiautomatic that has an electric pump. When people think of espresso maker barista machines, they envision these machines. Semi-automatic machines require you to grind and tamp the beans yourself The pump, however, regulates the flow of water and pressure. This is an excellent compromise between human control and mechanised reliability.
The Filter
Typically, compact espresso machine machines employ filters that separate the grounds of the coffee as they go through the hot water. The filter is also an essential part of the machine's temperature control, as it prevents overheating.
A filter also helps with flavor as it allows for a longer flowering phase. This allows the beans to release their flavor and improves extraction.
It is important to keep in mind that even the finest filter can make a bad cup of coffee. The quality of the beans, and the extraction process remain crucial.
It's here that the magic occurs. This is what makes espresso taste so good. The grouphead, often referred to as the brewhead, is where the portafilter (the device you put the ground coffee in) is located when you're making espresso.
Steam-driven espresso machines make use of hot water heated in an airtight container to create steam. The steam then pushes hot water into the grounds of the coffee under pressure. They are less expensive and are easier for the user 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, espresso machines powered by compressed air-pump are becoming increasingly popular. They make use of an air compressor to force hot water through the ground, and are more mobile than electric steam-driven espresso machines.
