Update…
I fitted the Red Clix axle and knob which descreases the grind size per click so that it’s easier to dial in for espresso. (10 clicks on the original = 20 clicks with Red Clix fitted).
I then dialled it in and got it into the sweet spot on grind #4. The adjustments resulted in the expected changes but the differences are quite significant even with just a single click adjustment.
(I posted above that it was very easy to grind but that was a filter setting. It’s definitely harder to grind at espresso setting but still around only 30 seconds which is pretty good, just a bit stiffer.)
So can it grind for espresso? Yes. Grinding at 9 clicks with a medium/light (closer to light) bean means that there is plently of adjustment left for lighter beans..
As for flavor, let’s just say it won’t be dethroning my 1Zpresso J-Max S travel grinder any time soon. The latter produces a fuller bodied espresso with choc-like notes. The C60 is …. just not doing it for my tasted buds. A bit brighter I guess. I’ll have to play a bit more and see if the discordant flavor is operator error or if its simply not an espresso orientated grinder.
I’ll try espresso again tomorrow with other beans and see how it goes. And I’ll give it a whirl with filter as well.
