The pressure of your machine is vital because it allows the water to flow through coffee grounds at the correct speed and intensity. If the pressure is too low, the oils and flavors won't be extracted properly. If the pressure is too low, the dissolved oils and flavors won't be extracted properly.
The pressure of your espresso machine can be controlled by adjusting the screw that is located on the espresso pump. Commercial machines and some of the top-end home appliances have rotary pumps that are adjustable. For home machines that are less expensive that have a vibrating motor, it is impossible to alter the pressure with DIY hacks. Companies such as Cafflano, however, are developing technology which uses Pascal's Principle in order to maintain pressure within the portafilter throughout the making process.
Temperature
Temperature is among the most crucial factors in a great espresso shot. A hot water can burn the grounds of coffee, which can result in bitter brew. The optimal temperature for extraction is 200 degrees Fahrenheit. This lets the water to extract all desired coffee flavors without burning the grounds or over-extracting.
