Nucleus Bloom WDT Tool (Retractable Dual-Mode Needles)
The Nucleus Bloom WDT Tool enhances your brew prep with retractable dual-mode needles that break up clumps, lift chaff, and smooth the brew bed. Built for pour-over and precision filter brewing, it improves clarity and consistency from the very first stir.
Low-friction, anti-static needles resist clinging fines and chaff, while a twist-to-retract body keeps them protected for transport and storage. A built-in FlowTip indentation tool creates a central divot to guide even saturation and prevent channeling.
