The pressure of your machine is crucial because it allows water to pass through the coffee grounds at the correct speed and intensity. If the pressure is too low the flavors and oils that are dissolved will not be extracted properly. On the other contrary, if pressure is too high the water will be forced through the coffee grounds too fast and you'll end with a weak, over-extracted cup of espresso.

Temperature
The temperature is one of the most important factors in brewing an excellent espresso shot. If the water is too hot, it could cause the coffee grounds to burn and result in an over-extracted bitter brew. The ideal temperature for extraction is 200 degrees Fahrenheit.

Using a high quality filtered water is vital to your machine's long term health and the taste of the coffee it makes.
