    Sep 25, 2019· When your grain is milled properly, you’ll move closer to achieving consistency and maximum brewing efficiency. Gap settings are not universal, and while there is not just one “ideal gap setting,” if you’re using a 2-roller homebrew mill, you can start with a gap setting ofright around 1.0 mm,andadjust from there.
