How to Make Espresso Machine Coffee
Espresso machines can make a delicious cup, but they require more care and setup than a regular coffee maker. You'll also need to grind and tamp the beans by yourself.
Pressure is the key to making espresso. The way espresso machines work is that a heating vessel heats the water to the ideal temperature before forcing it out of the spouts and into the grounds.
Temperature
Espresso is made by forcing hot water under pressure through finely ground coffee beans. The temperature of the water is essential to the quality of the final shot. Insufficient temperatures can result in the less extraction of the essential flavor compounds. The high temperatures cause excessive extraction, which can cause burnt or bitter tastes.
The ideal temperature for espresso is between 195 and 205degF. This temperature can be achieved using a grouphead designed to maintain the same temperature and stability throughout the process of brewing. The E61 is the most well-known group head because it provides the ability to stabilize temperature, pre-infusion 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 as well as crema. The optimal temperature will depend on the specific bean and roast but the general rule is that lighter roasts and higher ratios of brew require higher temperatures than dark roasts and lower ratios of brew. A high-quality thermocouple is crucial to keep the same temperature.
Pressure
During the brewing process espresso machine coffee is pressure-pushed through finely ground and tamped grounds. This causes chemical reactions which draw out flavors, oils and other soluble ingredients. The resultant beverage is usually richer and more flavorful.
The ideal espresso machine pressure should be nine bars which is the equivalent of sea-level pressure. The soluble compounds present in the coffee bean are best extracted at this pressure.
Some espresso machines advertise up to 20 bars of pressure. These machines may be able reach these pressure levels however, they might not be able to maintain them throughout the extraction.
To put it into perspective, one bar of pressure is equivalent to the 32 pounds per square inch PSI of the tire of a car. This is more than four times the pressure that a professional cyclist applies to their bike tires. Any serious home barista has to be able to control the pressure of their espresso machine, and also produce consistent espressos.
Water
Water is the most important ingredient in a great cup of espresso. The correct water will allow your beans to reach their full potential. Using the wrong water can cause problems such as clogged pipes or even harm your expensive espresso machine.
The best option is natural spring water that is high in minerals for ideal espresso extraction. This water will elevate the flavor of your espresso without the chalky mineral traces that come from tap water or bottled water. This is a great alternative to distilled or reverse osmosis filtered water, that can be too pure and cause problems with flavor.
You should read more not make use of a water filtration system that removes excessive mineral content from your tap water. This can cause flavor and extraction problems. A great option is to buy an instrument for testing water, which will reveal your local average water hardness. This information can be used to determine the best filtration system for your espresso machine.
Beans
Many coffee enthusiasts become enthralled in the whole process of making espresso. They get obsessed about a range of factors, such as temperature, water pressure, and viscosity. If one variable is not working, even a little the whole shot could taste bad.
The most important thing to consider in the matter of espresso is the beans used. Many believe that only certain varieties are suitable for espresso. While some beans are better suited for certain purposes however, any roast can be used for espresso. The difference between espresso beans and regular coffee beans is that espresso beans are roasted more in tipycally, well past the second crack which gives them a darker appearance and makes them more soluble in water.
Medium or dark roast beans are ideal for espresso, since they impart the espresso with richness and boldness. However, it is also possible to make great espresso with light roasted beans, especially if the beans are pre-ground (for convenience in the espresso machine).
Milk
Espresso and milk is a classic combination. The combination of espresso and milk is an old-fashioned. Not only does it improve energy levels but it also helps balance the bitterness in the espresso. There aren't many culinary combinations better than this one!
If you choose to buy an espresso machine that is able to make cappuccino or latte, be sure to look at how easy it is to use. A majority of the top espresso machines come with a jug that can be used for hot or cold milk and steam wand. They also come with an espresso portafilter that can be used to make the shot. Certain models also come with an integrated grinder or tamper.
The steam wand must be cleaned prior to using it for the first time every day (or after every cup of espresso) to get rid of any water that has condensed. This process only takes 30 seconds, but it is essential to keep your machine running smoothly. If you don't cleanse the system, it could cause bitterness and/or a accumulation of bacteria that could alter the taste or smell of your beverage. It's easy to do and should be part of your routine maintenance.
