Question about Bosch Hausgeräte TSM6A013B

In 20 seconds you have a powder that is comparable in size to packaged coffee powder, e.g. Jakob's Krönung.

I think "fine" is a very subjective term. I find that this machine can grind coffee very finely. Since the beans don't just slide through the grinder from top to bottom, you determine the grind yourself depending on how long you let it run.
