How to Make Espresso Machine Coffee An espresso maker can make delicious cups of coffee but it needs some additional setup and upkeep than a standard drip coffee maker It also requires you to grind and tamp your own beans The primary ingredient to make espresso is pressure Heres how an espresso machine works a heating vessel warms water to the perfect temperature before forcing it through the grounds and out the spouts Temperature Espresso is created by forcing hot water through finely ground coffee The temperature of the water is essential to the quality of the final shot Insufficient temperatures cause under extraction of essential flavor compounds High temperatures can cause over extraction which may cause bitter or burned taste The ideal temperature range for espresso is between 195 and 205 degF This temperature is reached by using a group head that is designed to ensure stability and a consistent temperature throughout the brewing cycle The most popular type of group head is the E61 that offers an array of temperature stability preinfusion capabilities and lever control When altering the espresso machine to accommodate different roasts and brew ratios it is crucial to take into consideration the effect of temperature on extraction yield and crema The ideal temperature will differ depending on the roast and beans However generally speaking it is believed that lighter roasts with higher brew rate require higher temperatures In addition a high quality thermocouple will be essential for maintaining a consistent temperature Pressure During the brewing process espresso machine coffee is pushed through finely ground and tamped grounds This triggers chemical reactions that extract flavors oils 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 components in the espresso bean are best extracted at this pressure Some espresso machines advertise up to 20 bar of pressure These machines might be able to attain these pressure levels but they may not maintain them throughout the extraction To put it in perspective For a better understanding one bar is equivalent to 32 pounds per square inch PSI of the tire of a car Its four times the pressure that a professional cyclist uses to pump up their bike tires Every serious home barista needs to be able to control the pressure of their espresso machine and make consistent espressos Water Water is the most important ingredient in a good cup of espresso The right water allows your beans to extract their maximum potential However the wrong kind of water can cause issues such as clogged pipes and damage to your expensive machine The best choice is a natural spring water that is rich in minerals to ensure optimum espresso extraction This water will enhance the taste of your espresso without chalky mineral traces that are found in tap water or bottled waters This is a great alternative to distilled water or reverse osmosis which could be too filtered and cause problems with flavor However you should never use filters that remove too many minerals from your tap water as this can also cause extraction and flavor issues The best option is to purchase a water test kit that will tell you the local average hardness espresso coffee machine can then be used to determine the right filtration system to provide the proper water requirements for your espresso machine Beans Many coffee enthusiasts get very involved with the whole process of making espresso They ponder a myriad of variables including temperature water pressure beans milk viscosity and other aspects If one of these variables is not working even a little the whole shot could taste bad The beans used are the most important factor when it comes to espresso Many people believe that only certain kinds of beans are suited to be used in espresso Although some beans are more appropriate for certain purposes any roasted coffee bean can be used to make espresso Espresso beans are roasted longer than regular coffee beans tipycally over the second crack This makes them appear darker and makes them more watersoluble Dark or medium roasted beans are ideal for espresso since they give the espresso a richness and a boldness Lightly roasted beans can be used to make great espresso especially when they are ground prior to use to make it easier to use an espresso maker Milk Espresso and milk are a classic combination The combination of milk and espresso is a classic It does not only increase energy levels but it also helps balance the bitterness in the espresso There are few culinary duos better than this one When choosing an espresso machine capable of making latte or the cappuccino as well you need to think about how easy it will be to use A majority of the top espresso machines come with a jug that can be used for hot or cold milk as well as steam wand They also have a portafilter to pull the shot Certain models have an integrated grinder tamper or frother The steam wand needs to be cleaned prior to using it for the first time in a day or after each cup of espresso to eliminate any condensed water This process is only 30 seconds but its vital to keep your machine running smoothly Failure to cleanse can cause bitter taste or accumulation of bacteria that may alter the flavor and aroma of your drinks Its simple to do and should form part of your regular maintenance schedule
