WHY IT MATTERS
Why distribution matters
Fewer clumps
Fine needles break up clumps that create uneven density in the basket.
Less channeling
An even coffee bed stops water from finding weak spots, which cause sour or bitter shots.
Repeatable results
The rotary motion covers the basket in a consistent pattern, shot after shot.

FAQ
Frequently asked questions
What is WDT?
WDT stands for Weiss Distribution Technique: stirring ground coffee with fine needles to break up clumps and even out the coffee bed before tamping.
Do I still need to tamp?
Yes. The WDT tool distributes the coffee; you still tamp afterwards to compress the puck.
Can I use it with a distributor?
Yes. Many baristas use a WDT tool first, then a distributor to level the surface before tamping.
