Cringe-Worthy Grain Crushing Methods Put to the Test ...
The purpose of grain crushing is to crack open the outer husk of the grain, exposing the rich center. Well-milled grain will leave the husk in tact, like the opening of a clam. This will make the grain bed more coarse in the fermenter or grain bag, which will allow the water to pass through and remove the nutrients you need from within.
