When brewing pour-over, many people deliberately pursue a coffee bed with uniform depth and a neat shape; likewise, many coffee enthusiasts with an obsession for details also make it their goal to knock out a whole, unbroken puck when extracting espresso.

Just like the coffee bed, whether the puck is intact cannot directly determine whether the cup of coffee tastes good or not. However, the state of the knocked-out puck can indeed reveal from the side whether the extraction was ideal. The reason is that every action of tamping the coffee grounds affects whether the puck can ultimately fall out intact, and these actions are precisely the core steps that determine coffee quality.
