I figure the Corona mill would be fun to tinker with until I save up for a the real deal. Just another home brewer trying to save a buck.
I used one for a few years. I typcially do half batches and even then it was a chore to crank through 5-6lb of malt, but I generally got a good looking crush. conditioning the malt prior to crushing helped keep the husks intact.
It also works well for unmalted grains (like wheat) that are pretty hard on a roller mill.
And back to the topic, I got a small freezer for a fermentation chamber a few days ago. My first fermentation is going now, an alt at 56F.
