Why does coffee grind level cause espresso grinder jams?

A clogged espresso grinder that stops dispensing grounds is a common barista problem, especially during the morning shift. The cause is usually the coffee grind level set too fine for the current beans, along with retained grounds, moisture or worn burrs. Fixes include cleaning the chute and burrs, checking the dose, and adjusting the grind coarser before pulling another shot.

Dialing in espresso depends on more than skill. The condition of the beans, weather changes and equipment status all affect the result, and even experienced staff can waste more than half a bag of beans on a difficult day. Working methodically through grinder maintenance and small grind adjustments helps identify the fault and reduce repeat clogs at any barista level.
