The verdict
WDT, the Weiss Distribution Technique, means stirring the grounds in the basket with fine needles before you tamp. Normcore's listing describes the job plainly: break up clumps so the coffee sits evenly, which gives a more even extraction and less channeling. It matters most with a single-wall basket and a grinder that clumps. With a pressurized (dual-wall) basket it does much less, because Breville's own manuals say dual-wall baskets regulate the pressure and help the extraction regardless of grind, dose, tamp or freshness. This V3 has nine stainless steel needles in an aluminium and walnut handle, and comes with a stand.
