- A plain cylindrical container (e.g.Acaia, Rhino, or the one that comes with the Niche Zero) that you flip onto your portafilter basket to transfer the grounds. To distribute/break up clumps, you could stir the interior with a whisk/WDT tool and/or give a shake if you cover the opening.
- The Lyn Weber Blind Tumbler & Shaker that has a central "plug" that you can stir to distribute grounds, and lifting the plug turns the receptacle into a chute that dispenses coffee from the bottom into your portafilter.
I have a Baratza Sette that I grind directly into my basket (18g ridgeless VST), but even though clumping is fairly minimal, I'm still getting some channeling (not using any kind of WDT in the basket). Just wondering if the grind-into-a-cup-and-distributing method would further reduce any chance of channeling, and whether a $20 Rhino dosing cup is just as effective as the $40 Acaia or $80 Lyn Weber!
