Inconsistent shots start with uneven puck prep. The UFO Series WDT distribution tool solves that problem at the source, breaking apart clumps before they ever reach your tamp. If you have been chasing channeling fixes downstream, this is where the real correction happens. Why Your Espresso Puck Prep Needs WDT Grinders clump. Even high-end flat burr sets produce fines that stick together, creating dense pockets that water exploits as channels. A quick stir with a paperclip does not cut it. Nine precisely arranged 0.25mm stainless steel needles deliver 360-degree concentric distribution, separating every particle for a uniform bed density that extracts evenly from edge to center. Adjustable Needle Depth for Any Dose Not every dose fills the basket the same way. The rotating top-mounted needle system is fully reversible and detachable, letting you dial in penetration depth to match your dose weight and basket size. Whether you pull 18g in a standard basket or 20g in a deep competition basket, the needles reach exactly where they need to go. A silicone base grip sits flush against your portafilter rim, preventing rotation and protecting the basket surface from scratches. No wobble, no slipping, just smooth, controlled stirring every single time. Built for Daily Barista Workflow The one-piece integrated body keeps everything compact and easy to clean. Rinse the needles, wipe the base, and it is ready for the next round. Durable construction means this tool handles hundreds of shots without needle deflection or loosening.
