  „Portafilter Sneeze: on pump and piston espresso machines that do not feature a pressure release system, removing the portafilter too soon after brewing a shot can result in the instant release of pressure in the brewhead, causing extremely hot and wet coffee grinds to spray and cause potential injury. When you complete the brewing of an espresso shot, some of the 135 PSI of pressure remains in the portafilter, and normally takes 30 seconds to a minute or longer to bleed off, allowing safe removal of the portafilter.“
