Product Description
The ARO PortaStack™ | Stir (WDT) Bundle is the puck prep system for espresso enthusiasts who want precise, hands-on control over distribution and a clean, organized workflow without adding a shaking step. Designed for consistency and efficiency, this bundle keeps puck preparation deliberate and repeatable from dosing through tamping while minimizing mess and variability.
This configuration skips the shaker and begins directly after dosing, using the ARO® Manual WDT v2 for the distribution step. Each tool works together as part of a single integrated system, with the Manual WDT v2 breaking up clumps and redistributing density to create a uniform puck before tamping. The result is a streamlined, distribution-first workflow built around magnetic organization, premium materials, and full manual control in a more cost-efficient configuration.
