Yesterday I was out at Stora Hällsta, the organic farm where I buy my barley and rye for koji making, as well as other farm products.

They have a full battery of milling machines, including a huller for hulling barley. When I order whole grains for koji making, I have them run through the huller i little extra, so that the koji mold grows better. That goes for the rye too, even tho it does’t need hulling.
