Closest alternatives
WDT tools, like Normcore's, use a cluster of fine stainless-steel needles to stir and de-clump ground coffee in the portafilter — the Weiss Distribution Technique named for John Weiss, who popularised it. By breaking up clumps before tamping, WDT markedly reduces channeling and improves shot consistency, and it became one of the most recommended low-cost upgrades in home espresso.
Pros
- Reduces channeling
- Improves espresso consistency
- Inexpensive upgrade
Cons
- Adds a prep step
- Marginal for non-espresso
