Description
Channeling ruins great shots before extraction even starts
Clumped grounds and dry pockets in the puck cause water to carve channels instead of flowing evenly through the coffee bed. A WDT comb breaks up those clumps in seconds, giving every shot a fair, even pull.
Precision prep, without the fuss
The Weiss Distribution Technique is standard practice at competition level and in serious home setups across India. This WDT comb puts that consistency within easy reach — no bent paperclips, no improvised tools.
