Any higher or lower level of pressure results in imperfect extraction, typically producing espresso that is too strong or too weak. Grind Size: The Heart of Espresso If your shot gushes out, the grind is too coarse. If it drips too slowly, the grind is too fine. A 25-30 second extraction time for a 25-30ml single shot is the target.The 10-second rule for espresso is a general guideline that suggests a well-brewed espresso shot should take around 10 seconds to start dripping from the portafilter.
