The change from nice hand grinders (Knock Feld 2 and Helor 101) and the Fellow Opus to the Fellow Ode 2 was drastic. The Ode 2 produces very few fines which greatly increases clarity and the speed in draw down time for the water through the grounds. I am doing pour over not espresso.
The hand grinders and the Opus all produce far more fines than the Ode 2.
