Helps create a flatter and more even-looking coffee bed before tamping.

After dosing or WDT preparation and immediately before the tamper.

WDT works through the coffee; a distributor works across the surface.

Compresses the prepared grounds into a stable, level bed for espresso extraction.

Once distribution is complete and just before the portafilter goes into the machine.

Distribution arranges the coffee; tamping finishes the puck.

Helps keep loose grounds inside the basket while grinding, dosing or using a WDT tool.

During the early preparation stage, before the coffee bed is tamped.

It gives the basket temporary taller walls while you work.

Creates a physical layer between the coffee puck and the machine's shower screen.

After tamping and before locking the portafilter into the espresso machine.

It is the final layer placed above the coffee before brewing begins.

Lets you observe the underside of the basket without bending down toward the machine.

While the espresso shot is actively flowing.

Preparation tools change the puck; a shot mirror simply helps you watch what happens next.
