    Unfortunately WBC is rather slow on aligning the competition rules with new research. Under current WBC Rules and Regulations barista will be disqualified if anything other than ground coffee and water is placed in the portafilters.

    Similar to losing points on no (or broken) crema..

    Also competitors are allowed to use their own tampers.

    That’s true!! Lately I’ve been putting paper filters on the bottom, following Gagne’s research that these increase extraction to the point that even a misplaced bottom filter is better then no filter.

    I haven’t seen that in the comp yet.

    ha ... interrsting observations. Try and make sense of all that lot. The ultimate conclusions, as always, must be made by testing and observing on our own coffee bench. Thank God we don't have to come up with an EU approved standard for espesso prep. It would probably start another war.

    I also noted that the US champ did wdt as well, but no ocd. The 2021 winner did ocd but not wdt.

    The tool that Anthony used for wdt was a lot quicker than the US contestant.

    This is why the OCD exists at all. There is a point awarded for "level bed before tamping", so Sasa created what he did for his winning routine. Everything after that is just marketing.

    what surprised me about his puck prep is that he WDT, then OCD, then tamped with a self leveling tamper.

    You can see his and the other routines on YouTube
    Just bought this https://coffeesnobs.com.au/forum/mar...3mm#post929592 and it's all your fault Budgiesmuggler

    I don't call these devices distributors but rather levellers and that study confirms it. I use WDT and RDT and a Bravo "leveller" (even though its called a distributor) not to distribute the grind, I find WDT does a good job of that, but rather to level the top surface before tamping. Others call that raking. My shots are very consistent so I'll definitely stick with it and as JohnA says, whatever works for you. Also I've seen many of the studies that compare OCD type devices with not using an OCD device and showing EY% comparisons etc but not one of them that I've seen has altered the depth of the leveller/distributor as part of their trials which can have a large effect on the final result.

    Im not sure if OCD adds anything extra, but its something i have always done, doesnt take much time or add much time to prep, so just continue using it.
    I use a leveling calibrated tamper (normcore) and puqpress and find the results to be identical.

    I say whatever works for you, if you are getting the results in the cup, stick to it, dont change over because x or y said its better. The beauty of this hobby is you can try stuff for yourself and see what gives you the best results

    I know he is now the Man, but it does not necessarily follow that using OCD helped. No one knows. Maybe, maybe not. If I am getting 9 out of 10 consistency with my shots I'm not going to add it. If I was getting 7 out of 10, I'd definitely try adding it to the workflow. As it is, I RDT and WDT and POT (Poland Overdose Technique 🤪) and that's probably enough. That said, I've love to read any theories that anyone has as to why OCD after RDT and WDT and POT is a good idea***

    A point of difference with his workflow is that most people tried OCD instead of WDT as opposed to after WDT. DavecUK tested that idea by placing tiny white grain particles in with the coffee grinds and he found that the distibution of grinds was not great with OCD on its own. It spun the grinds around the top half of the basket only.

    For sure WDT and a self levelling tamper are almost universally accepted as improving consistency. I've seen test results on WDT from John Weiss who shared the results given to him by more than on independant tester. As for the self levelling tamper, well it all but guarantees an even tamp.

    I was reading elsewhere that the leveller is used a lot in competitions because it makes the puck
    Look like even distribution, and therefor gets more points. But has limited use in improving extraction.

    I was at the championships and all of the finalists I watched on Friday used self-levelling pressure calibrated tampers.

    The Force tamper was the offical tamper of the championships so that probably also had something to do with it too.

    I was interested to see Anthony use the distributor. I stopped using one when I began using WDT. Might need to try it again!

    why did it surprise you?

    I do the exact same thing, always works a treat
