What does a WDT tool actually do?
It uses fine needles to break up clumps in your ground coffee so water flows evenly through the puck. The result is fewer sour or bitter shots caused by channeling.
Do I need a dosing funnel?
If you stir with a WDT tool or grind straight into the portafilter, yes. It keeps grounds in the basket and off your counter.
Why use a bottomless portafilter?
It lets you see the shot coming straight out of the basket. An even, centered stream means your prep is good. Spurts or thin spots show you where channeling is happening, so you know what to fix.
