Important Parts of an Espresso Machine
A top espresso machine should provide a robust and rich-bodied shot of coffee, with a full-bodied aroma and a strong flavor. This requires high levels of temperature and pressure.
You must also be aware of the crema, a golden brown layer that gives the espresso its distinctive color and taste. There are four major types of espresso machines: manual, semi-automatic automatic, super-automatic and semi-automatic.
Water reservoir
The reservoir of water is the container in which you store the cold, filtered water that is supplied to the espresso maker. It is usually removable, and has a lid to keep the water free of dust and dirt. It is an important part of the espresso machine and must be kept clean to avoid blocking. Pour vinegar into the reservoir to cleanse it. Let it run for several minutes.
The espresso machine makes use of water to pressurize coffee grounds to extract flavors oils, caffeine and flavors. It also produces the foam known as crema. Achille Gaggia designed the first espresso machines, which employed pistons and levers for high-pressure coffee. Gaggia's spring-piston levers drove the water through the coffee and into the cup, introducing new terms for what consumers called "coffee cream" (crema).
The pump uses electricity to push water through the heating element to heat it up to the ideal temperature for brewing of 195 degrees Fahrenheit. The pump is usually situated at the bottom of the machine. It is connected to a tube which runs through the heating elements. The tube is also connected on both ends to the cold-water tube and the hot-water tube. It also goes under the resistive heating element, that is covered with white grease, which helps keep the plate warm.
Pump
The pump is what makes an espresso machines work and there are many types. Some machines employ a vibration pump, also known as a vibe pump, which uses an electromagnetic motor that moves between the sides of the form of a coil at 60 pushes per second. The pump then forces water through the portafilter, and out of the spouts. Some pumps utilize an energy source known as thermoblock, also known as thermocoil, to warm the water precisely to the temperature desired for brewing. These systems allow for the control of temperature and pressure, both of which are important for a quality extraction.
Pump-driven espresso machines could be equipped with a spring, piston design, or an electric pump, however they all require water to flow through the coffee grounds under high pressure. The higher the pressure, the more delicious the extraction. The pump ensures that the coffee is evenly distributed and helps to make good crema.
Espresso machines that are piston-driven or steam-driven are also available. Steam pressure is used to force water through the grounds of the coffee in a steam-driven espresso machine. This kind of espresso machine is less expensive but doesn't produce as much pressure for the extraction. There are also air-pump-driven machines, which are lighter and smaller, but do not require a boiler and can be powered by hand pumps or a canister of compressed air (such as N2 or CO2). Air-pump espresso makers yield less espresso when compared to pumps-driven machines, however they may be more convenient for certain people.
Steam Wand
The steam wand is a thin pipe made of metal that comes out of the espresso machine and releases steam hot and pressurized into your milk to make foamy drinks such as cappuccinos and lattes. The wand can be used to heat cocoa, tea or any other hot drinks. The wand has a variety of holes that you can turn on and off to regulate the amount of steam released. Certain machines come with the traditional wand while others come with a Pannarello that is simpler to use but does not produce foam suitable for latte art.
If you're having issues making your milk frothy, it could be because your espresso machine has a problem with its anti-vacuum device. This valve is designed in order to prevent air from being absorbed by the steam wand when it is in operation. You can test it by lower the steam wand and watching for a whirring sound. If you hear a hissing sound it means that air is being drawn into. It is recommended to raise the wand a little to allow it to sink completely.
You can also test the anti-vacuum by taking off the wand, then washing it in warm water using a soft bristled brush or sponge. Cleaning the wand is vital to avoid clogs which could affect your frothing. If you're unable to fix the issue on your own, you can always call an expert technician or the manufacturer for assistance.
Control panel
The control panel enables users to modify and configure settings. These include coffee strength as well as volume of milk. These settings are saved in memory and can be changed at any time. The display will indicate when the machine must be descaled, and if the water reservoir is full.
Most espresso machines come with hot water dispensers. This is usually found next to more info or between the groups. This can be used for coffee or to heat cups if needed. It can also be used for cleaning and rinsing. Many models have pressure gauges on the front of the machine that indicate the current pressure in the boiler.
There is also a brew switch which controls the brew cycle and the number of shots. This is crucial as the size of the espresso shot is determined by the length of time the grounds are in direct contact with the water. If you wish the switch could be used to initiate the steaming process.
The control system on this espresso machine is a little dated, but it still is user-friendly. It has a narrow LCD which feels more like an ordinary LED. It is easy to navigate through the menus. However there is a slight learning curve for those who are new to espresso machine use. The machine's ability to keep a constant temperature is impressive. It keeps a perfect water temperature between 194deg - 208deg F throughout the entire brewing process. This ensures a perfect extraction of aroma and a premium cup every time.
