The pressure of the espresso machine is crucial because it allows water to flow through the grounds of your coffee with the right speed and in the right amount. If the pressure is too low the flavors and oils that are dissolved won't be extracted properly. On the other however, if the pressure is too high, the water will be forced through the coffee grounds too fast and you'll end up with a weak and over-extracted cup of espresso.
You can regulate the pressure of your espresso maker by changing the screw that is attached to the espresso pump.

For the cheaper home machines that utilize an oscillating pump, changing the pressure isn't possible without using DIY hacks. Companies like Cafflano, however, are developing technology that is based on Pascal's Principle in order to maintain the pressure inside the portafilter throughout the brewing process.
Temperature
Temperature is among the most crucial factors in the perfect espresso shot. The water that is too hot can scorch the coffee grounds, resulting in a bitter coffee.
