What it means

The downward force used when compressing coffee in the basket. Common espresso folklore cites exact force numbers, but repeatability and levelness usually matter far more than raw strength. Obsessing over tamp pressure easily distracts from the bigger drivers of puck quality — grind, dose, and distribution.

Distribution

Puck problems usually start with density and levelness.

Level the coffee deliberately before tamping.

Tools that help you see mistakes

Naked Portafilter

Make weak paths visible instead of theoretical.

Use a bottomless portafilter when dialing in or training, even if you return to a spouted one for service.

What people mean when they say "extraction"

Espresso Extraction

Puck prep only matters because it changes extraction.

Separate extraction from strength in your thinking. One asks how much was dissolved, the other how concentrated the drink feels.

The numbers that define the shot

Dose

A stable puck starts with a stable dose.

Use a scale for every dose when dialing in. Precision here saves time everywhere else.
