I found a store in my area to buy wheat berries. I do not want to invest in a proper grain mill until I am sure that I can figure out what I am doing. I know I can use a blender if I have to but I was wondering if I could use this coffee grinder/mill. I know it will only hold a small amount in the hopper. http://www.antiquecountrystore.com/coffeemill/spong1.jpg This is not my photo, but I do have that grinder/mill (from my Dad). Any thoughts?
