A few years ago I bought what I thought was a grain mill at a homebrew store. I wanted a mill with knurled wheels that could crush grain. This device does that but it was completely inappropriate for malted barley and its related cousins. Basically, the wheels are too close and it crushes the grain too much, almost into flour.
I found another grain mill for beer malts but kept this one anyway. Someone later informed me it's called a flaker (rather than a mill). It's got a few thickness settings and eventually gets the grains crushed into a very coarse powder. Shown here is a collection of rye berries, wheat berries and flax seed that have been crushed (several times through the finest setting). I can do several hundred grams in about 10 minutes. It's strictly low output. To make some really grainy breads, I substitute 1/3 of the total amount of flour with whole grain. I'll show you an example in the next post.
