I raise my hat to everyone who has participated to TGP, especially Jim (and including the sponsors). The project, including the comparisons and scoring of the grinders against the Robur is an invaluable resource and reference for many.another_jim wrote:I am adding the detailed scores that I'm keeping for later analysis at Teme's request. Teme is not one of the grinder testers, since shipping the grinders to Copenhagen is somewhat awkward. He is, however, one of the heavy hitters when it comes to this whole review process. He has done exemplary work testing a whole set of grinders there, including publishing and interpreting the first ever enthusiast generated particle size comparisons among top grinders. Dan and the rest of us are eager for any input he might give to the final article. If he wants to see the detailed data, he gets it.
Thanks for the kind words. I personally feel that the limited testing I did on a few grinders could have been of more use if I had had more time, resources and counter space available
I will need to take some time now to digest all the information on the posts that the TGP has spawned, but I would be more than happy to contribute to the final article if you'd like.
FWIW, I had a chance to play around with the Conti Valerio MDM Conical (branded as LM) and I quite liked it (except for the fact that the grinder kept jamming on me - a faulty unit or an underpowered motor?). I had no grinder to compare it to in terms of taste so unfortunately no comment here other than that it produced a very good cup. I did not like the grind fineness adjustment much, though and it seemed fairly sensitive to the fineness setting. The doser was very good - it swept clean and dropped the grounds straight down into the PF no matter how hard one "thwacked".
As for the poll of this thread, I usually keep a small amount of beans in the (chopped) hopper to put some weight on the ones being ground. I clean the doser and chute with a brush after each session, but there's naturally some (ground and partially ground) coffee left in the grinding chamber. I therefore throw away the first few grams at the beginning of each session. I, too have noted that the shots ground with less weight on the beans do run faster, which can to some extent be compensated for by dosing a bit more. I do not see staleness as an issue as the beans are freshly roasted (I prefer 4-10 days from roast date) and they do not stay in the hopper for long (24 hours max).
