Important Parts of an Espresso Machine A good espresso machine should provide a robust and richbodied shot of coffee with a full flavor and intense aroma This requires a high temperatures and pressure Pay pay attention to the crema This goldenbrown layer is what gives rich espressos their distinctive flavor and color There are four major kinds of espresso machines semiautomatic manual automated superautomatic and semiautomatic Water reservoir The water reservoir is the container that holds the cold filtered water that is fed to the espresso machine It is usually movable and comes with an lid that keeps the water free of dust It is a vital component of an espresso maker and must be kept clean to avoid the clogging To clean it you can add vinegar to the reservoir and let it run for several minutes The espresso machine makes use of water to pressurize coffee grounds to extract flavors such as oils and caffeine It also produces the foam called crema The first espresso machines were created by Achille Gaggia who used pistons that were attached to levers to create highpressure coffee Gaggias springpiston levers drove the water through the coffee and into the cup introducing new jargon for what people referred to as coffee cream crema The pump is an electric device that pushes the water through the heating element to bring it up to the ideal temperature for brewing of 195 degrees Fahrenheit The pump is usually situated on the bottom of the machine It is connected to a tube that goes through the heating elements The tube is also connected at either end to hotwater and coldwater tubes It also passes underneath the resistive heating elements which are covered with white grease to keep the plate warm Pump The pump is what makes espresso machines work with and there are various types For instance certain machines use a vibratory or vibe pump that makes use of an electromagnetic motor that moves between the sides of an electric coil generating 60 pushes per second The pump draws water into the portafilter and then out of the spouts Some pumps utilize an heating system known as the thermoblock or thermocoil to heat the water precisely at the temperature required for making These systems permit the control of temperature and pressure which is essential for a successful extraction Pumpdriven espresso machines may employ a piston spring or electric pump However they all require that water be pumped through the grounds of the coffee at a high pressure The higher the pressure the better the extraction The pump helps ensure that the coffee ground is evenly distributed which helps to create a great crema Other types of espresso machines include pistondriven or steamdriven Steam pressure is used to push water through the grounds of coffee in a steamdriven espresso machine This kind of machine is less expensive but doesnt produce the same amount of pressure required for extraction There are also pumpdriven espresso machines which are smaller and lighter but do not require a boiler They can be powered by hand pumps or a canister of compressed air such as CO2 or N2 Pumpdriven espresso makers use less pressure than espresso machines driven by pumps but they may be more suitable for some Steam wand The steam wand is a thin metal pipe that shoots hot pressurized Steam into your milk for foamy drinks like cappuccinos and Lattes The steam wand can also be used to warm cocoa tea or other hot drinks The wand has several holes that you can turn on and off to regulate the amount of steam released Certain machines come with a traditional wand while others have a Pannarello wand which is more userfriendly but doesnt create the same kind of foam needed for latte art If youre having trouble with the frothing of your milk it might have a problem with your espresso machines antivacuum valve This device is designed to prevent air from sucking into the steam wand during operation You can test it by taking the steam wand off and watching for a whirring sound If you hear a hissing sound it means that air is being drawn in It is recommended to raise the wand a little to make sure it is submerged You can also test the antivacuum using the wand and washing it in warm water using a soft bristled sponge or brush It is vital to clean the wand to avoid clogs that may cause problems with your frothing If you are unable fix it on your own call a professional or the manufacturer Control panel The control panel of an espresso machine allows the user to configure and alter settings These include coffee strength and volume of milk These settings are saved in memory and can be modified at any time The display also indicates the time when the machine has to be descaled and indicates whether the tank is full The majority of espresso machines have a hot water dispenser This is usually placed near or between the groups It can be used to make tea or heat cups when needed It is also useful to clean and rinse A lot of models have gauges for pressure on the front of the machine that indicate the current boiler pressure There is also a brew switch that controls the brew cycle and the number of shots This is important as the size of the espresso shot is determined by how long the grounds are in direct contact with the water If you wish the switch can be used to initiate the steaming process The control system on this espresso machine is a little dated but it still offers easytouse functionality It has a small LCD that feels more like an ordinary LED This makes it easy to navigate the menus however theres a bit of a learning curve for people who are new to espresso machines The machines temperature stability is impressive as well The machine can maintain a perfect temperature of 194deg to 208deg F during the entire brewing procedure This guarantees a perfect aroma extraction and a premium cup every time
