Clumpy grounds are one of the biggest causes of channeling. A few seconds of stirring with a WDT (Weiss Distribution Technique) tool breaks up those clumps and spreads the coffee evenly across the basket, so water flows through the whole puck instead of finding the weak spots.

Why it helps
- Fine stainless steel needles break up clumps without compacting the bed
- More even extraction: less sourness, less bitterness, fewer sprayers
- Cap doubles as a stand, so the needles stay clean and protected on your counter
How to use
Dose into your basket (a dosing funnel keeps it tidy), stir in small circles from the bottom up for 10–15 seconds, tap to settle, then tamp.
