Now I get the "stabilize juices" part. Makes excellent sense.
While I grind my coffee every morning (burr grinder), because there is a noticeable difference in flavor, not sure that I'm ready to go that far yet for flour. Partly because I have coffee every morning, but don't bake bread or make pasta every day - a few times a month, maybe. Is there really a taste difference between good commercial (King Arthur) and home ground? Plus, is sourcing the grain hard? I'm a homebrewer and can get lots of different grains, but they aren't what you'd make most flours out of, for example, barley.
