How to Make Espresso Machine Coffee Espresso machines can create a delicious cup but they require more maintenance and setup than a regular coffee maker It also requires you to grind and tap your own beans The primary ingredient to make espresso is pressure The way espresso machines work is that an heating vessel heats water to the ideal temperature before forcing it out from the spouts into the grounds Temperature Espresso is created by forcing hot water through finely ground coffee The temperature of water is vital to the final shot Low temperatures result in less extraction of the essential flavor compounds Temperatures that are too high can result in excessive extraction which could result in a bitter or burnt taste The ideal temperature for espresso is between 195 and 205 degrees Fahrenheit This temperature can be achieved by using a grouphead that is designed to maintain the same temperature and stability throughout the process of brewing The E61 is the most wellknown group head as it comes with the ability to stabilize temperature preinfusion 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 vary depending on the roast and the bean However generally speaking it is believed that lighter roasts with higher brew rate require higher temperatures A reliable thermocouple is crucial to keep the temperature at a constant level Pressure During the brewing procedure espresso machine coffee is pushed under pressure through finely ground coffee grounds that have been removed This triggers chemical reactions which extract flavors oils flavors and other soluble components from the beans The resultant drink is usually more flavorful and richer than regular coffee The ideal espresso machine pressure should be nine bars which is the equivalent of the pressure of the ocean at sea level This is because it is at this pressure that the soluble compounds of espresso are the easiest to extract Some espresso machines boast up to 20 bars of pressure Although these machines can reach these levels of pressure however they may not be able to maintain the pressure during the extraction One bar of pressure is equal to 32 pounds per square inch PSI of a cars tire Its nearly four times the pressure a professional cyclist uses to pump up their bicycle tires Every serious home barista needs to be able to control the pressure of their espresso machine and produce consistent espressos Water The water that you use in your espresso maker is among the most important aspects of a great cup coffee The right water will assist your beans in reaching their full potential Using the wrong water can lead to problems like clogged pipes or even damage your expensive espresso machine For the best espresso extraction make sure you choose an organic spring with a high mineral content This water will enhance the flavor of your espresso without the chalky mineral traces you get from tap water or bottled water This is a great alternative to distilled or reverse osmosis filtered water which is often too pure and can cause issues with flavor However you should not use an water filter that removes too many minerals from your tap water because this can lead to problems with flavor and extraction The best option is to buy a water test kit which will provide you with the average hardness of your water in your area This can be used to identify the best filtration system to provide the right water specifications for your espresso machine Beans Many coffee enthusiasts get very involved with the whole process of making espresso They are obsessed with a variety of factors such as temperature water pressure and viscosity If one of the variables is slightly off the whole shot could taste bad The most important aspect when it comes to espresso is the beans used Many people believe that certain kinds are suitable for espresso While certain beans are appropriate for certain purposes but any coffee bean can be used to make espresso Espresso beans are roasted longer than regular coffee beans which is over the second crack This gives them a darker appearance and makes them more watersoluble Medium or darkroasted beans are the best for espresso as they impart the espresso with richness and boldness However it is possible to make great espresso using light roast beans especially when these beans are preground for convenience in the espresso machine Milk Espresso and milk are a classic combination Not only does the coffee boost energy levels but the steaming milk helps to offset the bitterness of the espresso and provides a delicious creaminess There are few culinary duos more perfect than this When you are choosing an espresso machine capable of making latte or a cappuccino it is important to consider the ease to use Many of the best espresso machines feature the jug which can be filled with cold or hot milk along with a steam wand as well as a portafilter that allows you to take the shot Some models also come with a builtin grinder as well as a tamper and a frother The steam wand should be purged before making use of it for the first time every day or after each cup of espresso to get rid of any condensed water This process will take only 30 seconds but it is vital to keep your machine running smoothly If you dont flush the system it could cause bitterness andor a buildup of bacteria which can alter the flavor or aroma of your beverage Its easy to do and should be part of your routine maintenance
