Important Parts of an Espresso Machine A highquality espresso machine will give a rich and strong shot of coffee with a full aroma and a strong flavor espresso machines uk requires high temperature and pressure It is also important to be aware of the crema a goldenbrown layer that gives a rich espresso its characteristic color and taste There are four types of espresso machines semiautomatic manual automated superautomatic and semiautomatic Water reservoir The water reservoir is a container which holds cold purified water that is then fed into the espresso machine It is usually removable and has a lid that helps keep the water fresh and free of dust It is a crucial component of an espresso maker and must be kept clean to avoid the clogging To clean it pour vinegar into the reservoir and let it run for some time The espresso machine makes use of water to pressurize coffee grounds and extract flavors oils caffeine and flavors It also produces crema the foam Achille Gaggia created the first espresso machines which utilized pistons and levers to create highpressure making Gaggias spring piston levers pushed water through the coffee into the cup This was the introduction of a new jargon coffee crème crema The pump is an electric device that pushes the water through the heating element to heat it up to the ideal temperature for brewing of 195 degrees Fahrenheit The pump is usually found on the bottom of the machine It is connected to a tube that is pushed upwards through the heating elements The tube is connected to both the coldwater and hotwater tubes It also passes underneath the heating elements that resist heat which are coated with white grease to keep the plate warm Pump The pump is the thing that makes espresso machine work and there are many types For example some machines utilize vibratory or vibe pumps which is an electromagnetic machine that moves between the sides of the coil to generate 60 pushes per second The pump pumps water into the portafilter and then out of the spouts Other pumps utilize the thermoblock or thermocoil heating system which will precisely heat the water to the temperature that is desired for the brewing These systems also allow for control of pressure and water temperature which is crucial for a highquality extraction Pumpdriven espresso machines can employ a piston spring or electric pump However they all require that water be circulated through the grounds of coffee at a high pressure The higher the pressure more flavorful the extraction The pump makes sure that the coffee is evenly distributed and helps to create a good crema Other types of espresso machines include pistondriven or steamdriven In a steam driven machine the water is forced through the coffee using steam pressure This type of machine is cheaper however it doesnt provide the same amount of pressure required for extraction There are also airdriven espresso machines which are smaller lighter and do not require steam boilers They can be powered with a hand pump or a canister with compressed air such N2 or CO2 Airpump espresso machines produce less espresso when compared to pumpsdriven machines however they may be more suitable for certain people Steam wand The steam wand is a thin metal pipe that is inserted from the espresso machine and releases steam that is hot and pressurized into your milk to make foamy drinks such as cappuccinos lattes You can also make hot liquid for cocoa or tea The wand typically has a few holes on its tip which you can turn off and on to regulate how much steam is released Some machines use an oldfashioned wand while others have a Pannarello wand which is simpler to operate however it doesnt create the same kind of foam that is required for Latte art If youre having trouble frothing your milk you might have a problem with your espresso machines antivacuum valve This device is designed to prevent air from getting into the steam wand when it is in use You can test this by lowering the wand and listening for a hissing sound If you hear a sound that is hissing this indicates that air is being drawn in You must raise the wand to allow it to sink completely You can also test the antivacuum valve by taking off the wand then cleaning it with warm water along with a softbristled toothbrush or sponge Cleaning the wand is vital to prevent clogs that could affect your frothing If you are unable to fix it yourself call a professional or the manufacturer Control panel The control panel permits the user to change and configure settings The settings include the strength of the coffee and the quantity of milk These settings are saved in memory and can be modified at any time The display also shows that the machine requires to be descaled as well as the amount of water in the tank full Most espresso machines come with a hot water dispenser This is usually placed next to or between the groups This can be used for hot tea or to heat cups in the event of need It can also be used to clean and rinse Many models have pressure gauges which show the current pressure of the boiler A brew switch is also available that controls the brew process as well in the quantity of shots This is crucial since the size of the espresso shot is determined by how long the grounds are in direct contact with the water The switch can be used to also start the steaming process if desired The control system on this espresso machine is somewhat outdated however it does provide easy to use features It has a small LCD which feels more like an ordinary LED This makes it simple to navigate through the menus although there is a bit of a learning curve for users that arent used to espresso machines The stability of the temperature is also impressive It ensures a perfect water temperature of 194deg 208deg F throughout the entire making process This provides perfect aroma extraction and ensures an even highquality consistent cup every time
