대략적인 공연예산: How to Make Espresso Machine Coffee
Espresso machines can produce delicious cups, however they require more care and setup than a standard coffee maker. It also requires you to grind and tamp your own beans.
Pressure is the key to making espresso. The way an espresso machine operates is that the heating vessel heats the water to the right temperature, then forces it out from the spouts into the grounds.
Temperature
Espresso is produced by pushing hot water, under pressure, through finely ground coffee beans. The temperature of the water is vital to the final shot. Low temperatures lead to a absence of flavor compounds. High temperatures can cause excessive extraction, which could cause bitter or burnt taste.
The ideal temperature range for espresso is 195-205degF. This temperature can be achieved by using an espresso group head that has been designed to maintain the stability of temperature and maintain a constant temperature throughout the brewing process. The most popular type of group head is the E61 that offers a combination of temperature stability as well as pre-infusion capabilities and lever control.
When adjusting the espresso machine for different roasts and brew ratios it is important to consider the effect of temperature on the extraction yield and crema. The ideal temperature will depend on the specific bean and roast however the general rule is that lighter roasts and higher brew ratios require higher temperatures than darker roasts and lower ratios of brew. A good thermocouple is crucial to keep the same temperature.
Pressure
When brewing espresso machine coffee is pushed under pressure through finely ground coffee grounds that have been tamped. This triggers chemical reactions that extract flavors, oils and other soluble ingredients from the beans. The resulting drink is usually richer and more flavorful than regular coffee.
The ideal espresso machine pressure should be nine bars that's equivalent to the pressure of the ocean at sea level. This is due to the fact that it's at this pressure the espresso bean's soluble compounds are most easily extracted.
However certain buy espresso makers machines advertise as high as 20 or 15 bars of pressure. They may be able to 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 32 pounds per square inch, or PSI, of the tire of a car. It's four times the pressure professional cyclists use when pumping up their bicycle tires. Every serious home barista needs to be able to control the pressure of their espresso machine and make consistent espressos.
Water
The water you use in your espresso maker is one of the most important aspects of a great cup of coffee. The correct water will allow your beans to extract their full potential. However the wrong type of water could cause issues such as clogged pipes and damage to your expensive machine.
For the best espresso maker extraction of espresso, Coffeee you should choose an untreated natural spring with a high mineral content. This water will enhance the flavor of your coffee without the chalky mineral trace that comes from tap or bottled water. This is an excellent alternative to reverse osmosis. It can be too filtered and cause problems with flavor.
But, you shouldn't use an water filter that removes excessive minerals from your tap water, because this could cause extraction and flavor issues. Get a water test kit to determine the average hardness of your water at the local level. This can then be used to determine the right filtration system to give you the correct water specs for your espresso machine.
Beans
Most coffee drinkers tend to be extremely involved in the process of making espresso. They obsess over a variety of factors, such as temperature, pressure in the water and viscosity. If one variable is even slighty off, the entire shot may taste bad.
The beans used are the most important thing when it comes down to espresso. It is often believed that only certain kinds of beans are suited for espresso. While certain beans are 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 for longer by tipycally extending past the second crack, which gives them their darker appearance and makes them more soluble in water.
Medium or dark roasted beans are the best for espresso because they give the espresso a richness and boldness. Light roasted beans can also be used to make excellent espresso, particularly when they are ground to make it easier to use an espresso maker.
Milk
Espresso and milk are a timeless combination. The combination of espresso and milk is an old-fashioned. It does not only improve energy levels but it also helps balance the bitterness in the espresso. There are few culinary duos more perfect than this!
When choosing an espresso machine capable of making latte, or the cappuccino as well it is important to consider how easy it is to use. Many of the best espresso machines feature the jug which can be filled with hot or cold milk, a steam wand and portafilters for pulling the shot. Some models also have a built-in grinder, tamper and frother.
The steam wand must be purged before using it for the first time each day (or after every cup of espresso) to clear out any water that has condensed. The process takes only 30 seconds, yet it is essential to keep your machine running smoothly. Failure to purge can result in bitter taste or a build-up of bacteria that could alter the taste and smell of your drinks. It's easy to perform and should be part of your regular maintenance routine.
