I'm going to be doing a couple beers this weekend that involve about 20 pounds of grain. While my local supply store provides a mill for free, I don't really feel like running back and forth for that if I can just do it with something I already have at home. My wife has a hand powered chopper for things like vegetables, etc. While it will take awhile to get through the full amount of the grain, would that work as a cheap mill until I invest in an actual grain to have at home?
