How Does Machine Espresso Work?
Machine espresso utilizes precise pressure and incredible filter technology to produce the coffee we love. But how exactly does it work?
Espresso is created by forcing hot water under high pressure through finely ground coffee. The process is similar to that of making drip coffee. However it is the pressure that makes the main difference.
The Group Head
The group head is the portafilter that you insert when brewing espresso. It distributes water into the portafilter and regulates the pressure during the extraction. There are a variety of group heads each with their own advantages and drawbacks. Some are designed for the stability of temperature while some are specifically designed to handle pre-infusion. Others are made to control the lever. There are also some that have a combination of features, such as the E61, which is the standard choice for many baristas for its ability to provide multiple benefits in one package.
As you can see from the above photo the group head has a number of notches. It is possible to place your portafilter in these notches and then twist the head to lock it. There is also a rubber gasket which is located inside the notches, which helps create an airtight seal when you insert your portafilter into the machine. The notches on the head allow for an exact location of the portafilter which is vital to ensure an efficient extraction.
The group head is not just able to allow you to place your portafilter easily however it also keeps an even temperature. This is accomplished by cycling hot water around the portafilter, and through the brew basin, ensuring the temperature is always right for extraction. It is important to remember that even a small difference can make the difference between a great and a excellent espresso.
The Pump
The motorized pumps that are used in rotary espresso machines supply the nine atmospheric bar pressure needed to extract espresso. This is different from manual piston machines that use levers. This pressure is generated by pumping water through a heat-exchanger and then through the ground coffee.
Pumps are typically less expensive than piston-driven models, and they tend to last longer, although both types of machines can degrade with overuse and insufficient cleaning. Pumps are also more complicated mechanically, best espresso maker which can increase the cost of even simple models.
Certain espresso machines eliminate the pump completely and instead employ steam pressure to create espresso. This can lead to over-extraction as the boiler that makes steam also warms the water to boil. Additionally these machines typically have to rebuild their pressure between cups, which requires time and best espresso maker energy.
A large majority of espresso machines employ the rotary or vibration pump. A vibration model uses a rotating disk to generate pressure, whereas a rotating model pushes hot water through the ground at a fast speed. Both machines can produce excellent espresso but rotary machines are quieter, more durable and less likely to break down.
The Boiler
The boiler is used to heat the water to the right temperature for extraction. The resulting steam is then transferred to the portafilter which holds the ground espresso coffee and is then funneled down into the cup. The steam creates enough pressure to push the grounds of coffee through. This produces a layer of crema that is then poured over. This is a sign of a great espresso.
There are three types of espresso makers, which differ in the type of pump they use and how hot the best Espresso Maker is. There are many ways to control the amount of brew, as well as the size of the cup that can be produced by the machine.
The first espresso machines were steam types. The earliest espresso machines were steam types. The coffee tasted bitter and burned. The modern espresso machine was created by the Milanese producers Luigi Bezzerra & Desiderio Pavoni.
The most commonly used espresso maker is a semiautomatic machine with an electric pump. These are the things people think of when they think of an espresso machine. If you have a semi-automatic machine you have to grind the beans and then tamp them by hand. The pump provides regulated water flow and pressure. This is a perfect compromise between human control and mechanised consistency.
The Filter
Typically, espresso machines employ filters to separate the grounds of coffee when they pass through the hot water. The filter is also an essential part of the temperature control system, because it stops the machine from overheating.
A filter also helps with flavor since it allows for a longer flowering phase. This allows the beans to release their flavors, and improves extraction.
It is important to keep in mind that even the most efficient filter could result in a poor cup of coffee. The quality of the beans as well as the extraction, are still crucial.
It's here that the magic happens. This is what makes lavazza espresso machine taste so delicious. The grouphead, sometimes called the brewhead, is where the portafilter (the device you put the coffee grounds into) is placed when making espresso.
In an espresso machine that is driven by steam, hot water is heated in an airtight container to create steam, which then pushes the hot water through the grounds with high pressure. These kinds of machines are usually less expensive and easier to maintain than pump-driven models. They are however limited to create the ideal conditions for brewing as they only operate with 1-1.5 bar of pressure. The perfect shot requires 9-10 bars.
In recent times, espresso machines powered by a compressed air pump have become increasingly popular. They utilize an air compressor to push hot water through grounds, and are far more portable than steam-driven electric machines.
