What it means

A fine-needle tool used to break up clumps and even out coffee density in the basket before tamping. WDT stands for Weiss Distribution Technique. It is one of the easiest ways to improve puck consistency, especially on grinders that produce visible clumping — but overworking the basket slows workflow without fixing more basic recipe problems.

Where this leads

Each one pushes this into the cup, compares it, or helps you act on it.

Before the water hits

Distribution

Most accessories only matter if prep is already sound.

Level the coffee deliberately before tamping.

What the barista is doing

Puck Preparation

Refinements sit on top of routine.

Build a repeatable prep routine and protect it, especially when service speeds up.

Tools that help you see mistakes

Naked Portafilter

Use accessories to clarify what is happening, not mystify it.

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

Keep asking what actually changed in the cup.

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