How Do Espresso Machines Work?

Have you ever asked yourself where the name “espresso” used for some types of coffee comes from? It is an Italian word meaning express. As the word suggests it refers to the quick way of preparing coffee after it has been ordered.

During last couple of years the technology of making espresso machines has advanced greatly enabling you to provide some of numerous models offered for your own place. Before that things were much different, as you had to go to a coffee bar in order to drink an espresso. Now, you can do the entire job in the comfort of your own home making as much coffee as you like.

But, how to make a choice of the espresso machine that will best suit your needs? Well, it would be best to do some kind of test before you buy it. However, most of the shops won’t allow you to do that and then you can ask sales people to explain you how the machines work and what they can do.  Besides, you can just look at the window shops and the boxes.

An espresso machine works by compressing water down a pipe at “9 bars” of pressure at a temperature of 90 degrees or 195 Fahrenheit. Then the oil is let into the cup out of the coffee grinds making you nice and delicious coffee.

The time needed to get a double shot of good coffee is about 20-25 seconds. Nevertheless, the machine may be a little bit quicker or slower depending on coffee grinds and how coarse they are. There are some models on which you can change the pressure which will also change the time it takes to make the double shots of coffee. Also, some of the espresso machines have a milk wand enabling you to make coffee such as flat whites and lattes.

A few different kinds of espresso machines are available in the market such as the piston driven espresso machine, pump driven and steam espresso machines.
