Most if not all the manual box style grinders including the Kyocera ceramic take about 200 turns of the crank to get ~3T for espresso :Wow1:.
There's gotta be a better way to grind beans while camping![]()
Frankly, the Zassenhaus is faster at hand crank speed than the water boil time, so I'm happy with the speed.
Now, if you wanted to go nuts, you could find a grinder that has a DC motor, and do some electrical modification to make it run on automotive DC instead of household AC. I have the Baratza Virtuoso and it has a DC motor. I wouldn't bother, but it certainly would be interesting to see it operate on the trail.
