Yeah I’ve tried all manner of methods and I really can’t seem to see any improvement.

I’ve used a dosing cup/funnel for most grinders I’ve had even before the Philos so have a pretty established ‘tap the PF on the counter and tamp’ workflow but I thought I’d at least give WDT a good go given how many people seem to include it in their process.

@Adrianmsmith i think you’re right, the Philos grinds clump free so perhaps there’s just no benefit to WDT and is actually making it worse.

Try using the Spirograph WDT tool for consistency. Too many variables otherwise. The duration of WDT also matters. As mentioned above, not all grinders and beans benefit from WDT.

      I thought id heard it all, darent ask what you’ve been watching on YouTube 🤭😭

      I do agree not all grinders require wdt!!

          Adrianmsmith it’s from personal experience. It makes perfect sense that a Spirograph is the most consistent tool. I’m sure i am not the only person that finds them useful.

          The 3d printed ones are fairly cheap as well. In my experience it improves extraction both subjectively and objectively (in terms of EY) when grinds are clumpy as compared to using needles.

          I can see the grinders you use are high end. Not surprised that you don’t need to do anything else to improve extraction.

            Regarding YouTube videos, this is probably the most scientifically robust video I have watched 😊

              Yep, WDT tool is back in the cupboard for a few years until the next time I need to remember how pointless it is.

                I had the same issue with WDT when using a needle type and was barely hit more than miss but saw this come up and thought I’d give it a go and got to say 95% of the time I’ll get an even extraction.

                Emc2 Thx for the great video.

                Take aways:

                • Does matter
                • Affects the flow rates
                • Variability of extraction is higher without WDT.
