If you’re tired of spending more than an hour just to get your perfect espresso, then maybe it’s time for a new machine. This article will explain how hot an espresso machine needs to be.
How hot does an espresso machine need to be?
An espresso machine needs to be heated to around 190 degrees Fahrenheit to extract the flavor and caffeine from the coffee beans properly.
The coffee could become bitter and over-extracted if it is not at this temperature.
Who invented espresso?
Espresso machines were invented in the 1800s by a man named Luigi Bezzera. He patented his machine in 1884, and it became popular throughout Europe.
The espresso machine was first used in America in 1917 and quickly became popular there as well.
How to make an espresso
Espresso brewing is mixing hot water with finely ground coffee beans to create a strong yet smooth beverage. Espresso machines need to be at the correct temperature to produce optimal results.
Too low of a temperature and the coffee will not extract properly, while too high of a temperature can cause bitterness or over-extraction.
To ensure that your espresso machine is operating at the correct temperature, follow these simple guidelines:
Espresso machines should be placed on level surfaces with adequate ventilation.
Ensure your espresso machine’s boiler is clean and free of debris or oils.
Before starting your espresso machine, ensure the water reservoir is filled to the top of the tank with fresh cold water.
Preheat your espresso machine’s boiler before using it for the first time. Pour enough water into the boiler to cover the grounds (approximately 1-2 ounces per cup).
Turn on your espresso machine and wait until steam begins coming out of its exhaust port (about 10 seconds).
Quickly pour about 1/4 cup of boiling water into the machine, keeping the steam pressure as high as possible without creating any noise (the higher the steam pressure, the more flavor will be extracted from your coffee beans).
Immediately close off all air vents and place a filter holder on top of each group head. Place freshly ground coffee beans into each group head.
When you have finished brewing, discard any unground coffee beans left in the filter holders and replace them with new ones.
After brewing, turn off the espresso machine and wait for the steam to dissipate before pouring your coffee.
Now that you know how hot the espresso machine needs to be to make quality espresso, it’s time to learn how to adjust the temperature.
Sometimes, we forget that our machines are adjustable and can be adjusted based on what type of coffee we’re brewing. All you need to do is look for a dial behind the portafilter or at the front of your machine and turn it accordingly.
Remember that too much heat will result in burnt espresso beans, while too little heat will result in under-extracted coffee.
Make sure to experiment with different temperatures until you find what works best for you!
