Machine espresso makes use of precise pressure and amazing filter technology to make the delicious coffee we enjoy. But how exactly does it work? <img src="https://cdn.freshstore.cloud/offer/images/778/2223/quest-36569-espresso-coffee-machine-with-milk-frother-1-2l-water-tank-and-drip-tray-steam-ready-and-temperature-indicator-for-ground-coffee-beans-15-bars-of-pressure-2223.jpg" style="max-width:400px;float:left;padding:10px 10px 10px 0px;border:0px;">To make an espresso hot water is forced under high pressure through finely ground coffee. The process is similar to making drip coffee. However the pressure is the major difference. The Group Head As the name suggests, the group head is the place you insert your portafilter when making espresso. It is responsible for dispersing water into the portafilter and then controlling the pressure of the resulting extraction. There are several different types of group head each with its own advantages and drawbacks. Some are designed for temperature stability while others are designed to handle pre-infusion. Others are built to control the lever. There are even some that include a mix of features, such as the E61, which is considered the most popular choice among baristas due to its capacity to offer multiple benefits in one package. As you can see in the image above the group head comes with several notches where you place your portafilter before twisting it by hand to lock it in. A gasket of rubber is situated inside the notches to help create a seal when you insert your portafilter. The notches on the head permit an exact placement of the portafilter, which is crucial to ensure an even extraction. Apart from allowing you easily place your portafilter in, the group head is responsible to ensure that the temperature remains even. This is achieved by cycling hot water around the portafilter, and through the brew-basket to ensure that the temperature is at the right level to extract the coffee. This is crucial, since just a few degrees could be the difference between a good and excellent espresso. The Pump In contrast to manual piston machines which rely on a lever to pressurize water, rotary espresso machines rely on motorized pumps to provide the nine atmospheric bars of pressure that are required for espresso extraction. This pressure is built up by pumping water through a heat exchanger and then through the ground coffee. Pumps tend to be less expensive than piston-driven machines and tend to last longer, but both types of machines can get damaged through overuse and lack of cleaning. They also add mechanical complexity which can result in an expensive price for even the most basic models. Some <a href="https://telegra.ph/Espresso-Maker-The-Good-The-Bad-And-The-Ugly-04-04">espresso machine sale</a> machines do away with the pump entirely and utilize steam pressure to make espresso. This can cause over-extraction because the boiler that makes steam also warms the water to boil. These machines also have to constantly rebuild their pressure between cups. This requires energy and time. Many espresso machines employ the rotary or vibration pump, with a vibrating model using a rotating disc to create pressure and an rotary model that pushes hot water through the grounds under high speed. Both machines can make great espresso, however rotary machines are quieter, more durable and less likely to break. The Boiler The boiler is used to heat the water to a temperature that is ideal for extraction. The steam that is produced reaches the portafilter that contains the ground espresso and is then pumped down into the cup. In this process, the steam creates pressure to push through the coffee grounds. This results in a layer of crema that is then poured over. This is the hallmark of a great espresso. There are three types of espresso makers (<a href="https://wyatt-burke.federatedjournals.com/17-reasons-you-shouldnt-avoid-small-espresso-machine/">Federatedjournals official website</a>), and they differ in the type of pump they use and the degree of heat that the coffee is. There are a variety of ways in which the brew can be controlled and the size of the cup the machine can make. The first espresso machines were steam types. The earliest espresso machines were steam types. This led to the coffee tasting burnt and bitter. This is why the Milanese producers Luigi Bezzerra and Desiderio Pavoni created the modern espresso machine. The most common espresso machine is a semiautomatic model with an electric pump. These are what people imagine when they think of an espresso machine. With a semi-automatic <a href="https://git.openprivacy.ca/cavegrill6">espresso coffee machine</a> machine, you have to grind the beans and tamp them by hand. The pump is able to regulate the flow of water and pressure. This is a fantastic compromise between human control and mechanized reliability. The Filter Espresso machines usually use filters that separate the grounds of coffee from hot water. The filter is also a crucial element of the temperature control system, because it stops the machine from overheating. A filter also helps with flavor, as it permits a longer flowering phase. This lets the beans release their flavor and allows for better extraction. However, it is important to remember that even a top filter can produce a bad cup of coffee, because the quality of the beans and extraction is crucial. This is where the magic happens, and it's what makes an espresso really taste great. The grouphead (also called the brewhead) is where you place the portafilter - the thingy that you put the grounds of your coffee into when making espresso. Steam-driven espresso machines use hot water heated in an airtight container to make steam. The steam then pushes hot water through the grounds of coffee at high pressure. These machines are cheaper and are 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-driven espresso machines have been gaining popularity. They use an air compressor to push hot water through the ground. They are also more mobile than steam-driven electric espresso machines.
