MWJB I agree that most of the gear we use does not have any valid experimental data to support their use. Such robust testing can only be done by full-time academics. But what I would like to see is an acknowledgment of the limitations of the study and to refrain from making absolute statements such as the one about a 0.7% increase in EY.

I review a fair few research articles- this is perhaps why my expectations are a bit high.

    MWJB my mistake. I’ve corrected it in the post above

      Meh. I took the study as more “ You can remove a lot of faff in your process without much detrimental effects if you do this.”

      It’s not necessarily about what is best. What is good enough.

        Personally taste tests would always be well personal to the tester other than broadly saying good/bad imho. He would never win going that route instead using repeatably recordable numbers.

        However my simplistic view on the vid was overall how little there was between the various methods - so if i find a way to simplify further my workflow - or if I get some benefit in prepping my coffee its a win 😂

        And I have ordered a cheap blind shaker from amazon just to try it out by using that rather direct into my portafilter.

        I still need to try making a really under then over extracted shot just to see how it tastes for my taste buds… dont think I nailed that yet 👍

        Loonster The point is that the data doesn’t show that! You can’t make any conclusions based on it. I guess the only way is to try it yourself. I’ve ordered a shaker as well.

          Suddenly a rush on shakers 😂

          Though not the weber - 65 quid and then 30 odd shipping - plus you would get hit with VAT etc

            I got one for 15 from amazon but its coming from china.. i did sort of look at aliexpress and got alot of we dont ship to the UK

                  Emc2 aha - thanks for that - I will try that out 👍

                    Tried shaking the coffee in the grind cup this morning for about 20 seconds or so. Surprisingly, the espresso took longer to extract and tasted good. Not sure about the EY, but this method does seem to take away the need for deep WDT. ( I did puck rake though).

                    it is getting more and more ridiculous. instead of having a simple, smooth, relatively foolproof workflow - people are trying to make pulling a shot a ritual instead. As if only them know and can enjoy a good cup

                      delta76 I I think the video was about making the workflow easier? Not having to do WDT will massively improve the workflow and make things easier for beginners.

                          Emc2 Agreed I am hoping to reduce what (little) I already do 😂

                            Emc2 no I was saying in general, not specifically to the video. I tried to watch it but could not finish.

                            I am biased - because I like James a lot - but I wish we have more of this

                            in the end, his workflow is simple and easy. and it creates just as good espresso as with $200 moonraker whatever things. We (as the espresso world in general) are spending way too much time and money to optimize the last 1% where it could be gained much cheaper and easier else where.

                                delta76 - It’s all relative. You could argue that for some, when they see us with a machine on our couter top that weights 30kg and takes 35 minutes or so to warm up, weighing in and out, WDT (or stockflesh, or nswe or whatever we had back in the day) they must think we are just crazy insane.

                                You have to be happy with what works for you. If grind, tamp, pull works… Happy days. If you feel the need that things taste better adding further steps, happy days too.

                                    MediumRoastSteam if they make a quantifiable difference in cup quality (i.e. in blind test you have 8 out of 10 tasters agree that cup with this technique is better than cup with that technique), sure. but for now it seems like all added extra steps without any real benefits, just people think it does
