How to Make Espresso Machine Coffee
Espresso machines can produce an amazing cup of coffee, however they require more care and setup than a typical coffee maker. You also need to grind and tamp the beans yourself.
The key to making espresso is pressure. The way an espresso machine operates is that heating vessels heat the water to the perfect temperature, and then pushes it out from the spouts into the grounds.
Temperature
Espresso is produced by forcing hot water through finely ground coffee. The temperature of the water is essential to the final shot. Low temperatures result in less extraction of the essential flavor compounds. The high temperatures can cause over extraction, which may result in a bitter or burnt taste.
The ideal temperature for espresso is between 195 and 205degF. This temperature can be achieved using a grouphead that is designed to maintain the same temperature and stability throughout the brewing process. The most sought-after type of group head is the E61, which provides an array of temperature stability as well as pre-infusion capabilities and lever control.
When making adjustments to the espresso machine for different roasts and brew ratios it is important to consider the effect of temperature on extraction yield and crema. The ideal temperature will vary on the specific roast and bean however the general rule is that lighter roasts and higher ratios of brews need higher temperatures than dark roasts and lower ratios of brew. In addition, a top quality thermocouple will be essential to maintaining a consistent temperature.
Pressure
In the process of brewing, espresso machine coffee is pushed through finely ground and tamped grounds. This triggers chemical reactions that extract flavors, oils, and other soluble components from the beans. The resultant drink is usually richer and more flavorful than regular coffee.
The ideal espresso machine's pressure is nine bars of pressure, which is equal to the atmospheric pressure at sea level. This is due to the fact that it's at this pressure that the coffee bean's soluble components are the easiest to extract.
However some espresso machines advertise 15 or even 20 bars of pressure. While these machines are able to reach these pressure levels, they may not be able to maintain that level of pressure throughout the extraction.
To put it in perspective To put it in perspective, one bar of pressure is equivalent to 32 pounds per square inch, or PSI, of the tire of a car. It's more than four times the amount of pressure professional cyclists use when filling their bicycle tires. The ability to control espresso machine pressure and create consistent espressos is the key to any serious home barista.
Water
The water that you use to make espresso is one of the most crucial aspects of a great cup of coffee. The right water can assist your beans in reaching their full potential. However, the wrong water could cause problems such as clogged pipes or even harm your expensive espresso machine.
To get the most espresso extraction it is recommended to choose the natural spring that has a high mineral content. This water will enhance the taste of your espresso without the chalky mineral traces found in tap water or bottled water. This is an excellent alternative to distillation or reverse osmosis water, that can be too pure and can cause issues with flavor.
It is not recommended espresso and filter coffee machine to use a water filtration system that removes excessive amounts of mineral content from your tap water. This could cause taste and extraction problems. One option is to purchase a water test kit which will give you your local average water hardness. This information can be used in determining the best filtration system for your espresso machine.
Beans
Most coffee drinkers tend to be involved in the entire process of making espresso. They are obsessed with a variety of variables, including temperature, pressure of water, beans, milk, viscosity and other factors. If one variable is off even slightly, the entire shot could taste bad.
The beans used are the most important aspect when it comes to espresso. It is often believed that only certain types of beans work well to be used in espresso. While certain beans are than others for specific purposes however, any roast can be used for espresso. The difference between espresso beans and regular coffee beans is that espresso beans are roasted for longer and tipycally over the second crack which gives them an appearance darker and makes them more soluble in water.
Medium or dark roast beans are ideal for espresso because they give the espresso a richness and a boldness. However, it is possible to make great espresso with light roasted beans, particularly when the beans are ground prior to grinding (for convenience in the espresso machine).
Milk
Espresso and milk are a classic combination. The combination of milk and espresso is the most popular. Not only does it increase energy however, it also balances the bitterness in the espresso. This is one of the best pairings for a meal!
When choosing an espresso machine capable of making latte, or a cappuccino as well be sure to think about how easy it is to use. Many of the best machines include a jug to drink hot or cold coffee and a steam wand. They also come with a portafilter for pulling the shot. Some models come with an inbuilt grinder, tamper and frother.
The steam wand needs to be cleaned prior to making use of it for the first time in a day (or after every cup of espresso) to clear out any condensed water. This process takes about 30 seconds and is crucial to keep your machine operating smoothly. Inability to purge could cause bitter taste or accumulation of bacteria which can alter the taste and smell of your drinks. It's simple to do and should be part of your regular maintenance routine.
