How to Make Espresso Machine Coffee
Espresso machines can make a delicious cup, but they require more care and setup than a typical coffee maker. It also requires you to grind and tamp your own beans.
The most important ingredient in making espresso is pressure. Here's how an espresso maker operates: a heating vessel heats water to the ideal temperature, and then pushes it through the grounds and out the spouts.
Temperature
Espresso is produced by forcing hot water, under pressure, through finely ground coffee beans. The temperature of the water is essential to the final shot. Low temperatures result in less extraction of essential flavor compounds. High temperatures can cause over extraction and can lead to burnt or bitter tastes.
The ideal temperature for espresso is between 195 and 205degF. This temperature is reached by using a group head designed to maintain the same temperature and stability throughout the brewing process. The most well-known type of group head is the E61, which provides the stability of temperature with pre-infusion and lever control.
When altering the espresso machine for different roasts and brew ratios, it is important to consider the effect of temperature on extraction yield as well as crema. The ideal temperature will depend on the specific bean and roast however the general rule is that lighter roasts and higher ratios of brew require higher temperatures than dark roasts and lower brew ratios. In addition, a high quality thermocouple will be essential in ensuring a consistent temperature.
Pressure
During the brewing process espresso machine coffee is pressure-pushed through finely ground and tamped coffee grounds. This creates chemical reactions that extract flavors oils, flavors and other soluble ingredients from the beans. The beverage produced is usually richer and more flavorful.
The ideal espresso machine pressure is nine bars of pressure, which is equal to the atmospheric pressure at sea level. The soluble compounds found in the coffee bean are best extracted at this pressure.
Some espresso machines boast up to 20 bars of pressure. These machines may be able achieve these pressure levels, however, they might not be able to maintain them throughout the extraction.

It's more than four times the pressure a professional cyclist uses when pumping up their bike tires. Any serious home barista has to be able to regulate the pressure of their espresso machine and produce consistent espressos.
Water
The water that you use to make espresso is among the most crucial elements of a good cup of coffee. The right water will help your beans extract their full potential. However, the wrong water can cause issues like clogged pipes, or even harm your expensive espresso machine.
For the best extraction of espresso it is recommended to choose a natural spring with high mineral content. This water will elevate the flavor of your coffee without the chalky mineral traces that come from tap water or bottled water. This is an excellent alternative to distillation or reverse osmosis filtered water, that can be too pure and cause problems with flavor.
However, you should never use water filters that remove excessive minerals from your tap water, since this can cause problems with flavor and extraction. The best option is to purchase a water test kit which will reveal your local average water hardness. This can then be used to find the best filtration system to provide the right water specifications for your espresso machine.
Beans
The majority of coffee enthusiasts get very involved with the whole process of making espresso. They are obsessed with a range of variables, including temperature, water pressure, beans, milk, viscosity and other factors. If one of the variables is not functioning properly the whole shot may taste bad.
The beans used are the most important thing when it comes down to espresso. Many people believe that only certain types of beans work well to be used in espresso. While some beans are better designed for specific uses but any bean that is roasted can be used to make espresso. Espresso beans are roasted for longer than regular coffee beans, which is over the second crack. This gives them a darker appearance and makes them more water-soluble.
Dark or medium roasted beans are best for espresso as they give espresso shots a richness and boldness. However, it's possible to make great espresso with light roasted beans, especially if the beans are ground prior to grinding (for convenience in the espresso machine).
Milk
Espresso and milk is a traditional combination. The coffee doesn't just boost energy levels, but the steamed milk helps balance the bitterness of espresso and provides a delicious creamy flavor. There aren't many culinary combinations more perfect than this!
If you decide to get an espresso machine that is able to make cappuccino or latte make sure you consider how easy it is to use. Many of the best machines come with a jug for hot or cold milk, as well as steam wand. They also come with an in-built portafilter to take the shot. Some models also have an integrated grinder along with a tamper, frother and tamper.
The steam wand needs to be cleaned prior to using it for the first time every day (or after each cup of espresso) to remove any water that has condensed. The process takes only 30 seconds, but it is crucial to ensure that your machine is running smoothly. Inability to purge could cause bitter taste or accumulation of bacteria that can affect the flavor and smell of your beverages. It's easy to perform and should be part of your regular maintenance routine.
