Ten Espresso Machine Coffee Myths You Should Never Share On Twitter

How to Make Espresso Machine Coffee
Espresso machines can make delicious cups, however they require more care and setup than a regular coffee maker. You must also grind and tamp the beans yourself.
The key to making espresso is pressure. Here's how an espresso maker operates: a heater heats water to the ideal temperature and then forces it through the grounds and out the spouts.
Temperature
Espresso is made by forcing hot water, under pressure, through finely ground coffee beans. The temperature of the water is vital to the quality of the final shot. Insufficient temperatures cause under extraction of the essential flavor compounds. High temperatures cause over extraction, which can cause burnt or bitter tastes.
The ideal temperature range for espresso is 195-205degF. This temperature can be achieved by using a grouphead designed to ensure a constant temperature and stability throughout the brewing process. The E61 is the most well-known group head as it comes with temperature stability, pre-infusion capability and lever control.
When altering the espresso machine to accommodate different roasts and brew ratios it is important to consider the effect of temperature on extraction yield and crema. The optimal temperature will depend on the specific roast and bean, but the general rule is that lighter roasts and higher ratios of brews need higher temperatures than darker roasts and lower brew ratios. In addition, a high quality thermocouple will be essential to ensure a constant temperature.
Pressure
During the brewing procedure, espresso machine coffee is pushed under pressure through finely ground coffee grounds that have been put through a tamper. This causes chemical reactions that remove flavors, oils and other soluble ingredients. The resulting beverage is typically richer and more flavorful than regular coffee.
The ideal espresso machine pressure should be nine bars which is the equivalent of the atmospheric pressure at sea level. This is because it's at this level that the espresso bean's soluble compounds are most easily extracted.
Some espresso machines advertise up to 20 bar of pressure. While these machines may achieve these levels of pressure but they might not be able to maintain the same pressure throughout the extraction.
One bar of pressure is equal to 32 pounds per square inch (PSI) of a car's tire. It's also more than four times the amount of pressure that professional cyclists use when pumping up their bike tires. Any serious home barista needs to be able to regulate the pressure of their espresso machine to produce consistent espressos.
Water
Water is an essential ingredient in a good cup of espresso. The correct water will assist your beans in reaching their full potential. Using the wrong water can lead to problems such as clogged pipes or even damage to your expensive espresso machine.
The best choice is a natural spring water that is high in minerals to ensure optimum espresso extraction. This water will elevate the taste of your brew without the chalky mineral traces that are found from tap water or bottled water. This is an excellent alternative to distilled water or reverse osmosis, which can be too purified and cause flavor problems.
However, you should not use filters that remove excessive minerals from your tap water because this could cause problems with flavor and extraction. Buy a water testing kit to determine the average hardness of your water at the local level. This can be used to locate an filtration system that can provide the right water requirements for your espresso machine.
Beans
Most coffee drinkers tend to be very involved in the process of making espresso. They are obsessed with a variety of variables, such as temperature, pressure of water beans, milk viscosity and other aspects. If one of the variables is slightly off, the whole shot could taste bad.
The most important factor when it comes to espresso is the beans used. People generally believe that only certain kinds of beans work well for espresso. Although some beans are more suitable for specific purposes but any coffee bean can be used to make espresso. The difference between espresso beans and regular coffee beans is that espresso beans are roast for longer by tipycally extending past the second crack, which gives them a darker appearance and makes them more soluble in water.
The best espresso beans are generally medium roasted or dark roasted, which give the espresso shots their distinctive richness and vigor. However, it's possible to make great espresso using light-roasted beans, especially if the beans are preground (for convenience in an espresso machine).
Milk
Espresso and milk is a classic pairing. The combination of espresso and milk is an old-fashioned. Not only does it increase energy levels but it also balances the bitterness in the espresso. There are few culinary duos more perfect than this one!
If you decide to get an espresso machine that can also create cappuccino or read more latte make sure to consider how easy it is to use. The best espresso machines feature a jug that can be filled with hot or cold milk as well as a steam wand, and a portafilter for pulling the shot. Some models come with a built-in grinder, tamper, or frother.
The steam wand needs to be cleaned prior to making use of it for the first time throughout the day (or after each cup of espresso) to remove any condensed water. This process can take about 30 seconds and is crucial to ensure that your machine runs smoothly. Inability to purge could cause bitter taste or accumulation of bacteria which can alter the flavor and aroma of your beverages. It's easy to perform and should be part of your regular maintenance routine.
