Mahlkönig has come up for Atlanta with a new configuration of the K30 grinder to get rid of the clumping issue and was so kind to send me to Brazil a prototype before the WBC for testing.
I would like to share with the board the experience I had the last weeks testing and training with the Brazilian Barista Champion Yara.
In my opinion - that might be biased slightly - clumping has been reduced considerably.
I have put some pictures up here.
The coffee feels extremely fluffy and loose, no more big clumps.
Besides the exit, also the complete grinder housing has changed.
