*'''3-roller vs 2-roller''' - In a 3-roller mill, the grain is pre-crushed in the gap between the top two rollers, and then the grain flows into the gap between the drive roller and bottom roller, crushing it further. The top gap is fixed at around 0.060–0.070" which easily pulls in both wheat and barley, providing superior feed, and softening the starch without tearing up the husk.<ref name="monster">[https://www.monsterbrewinghardware.com/store/pc/FAQs-d2.htm FAQs.] Monster Brewing Hardware. Accessed May 2020.</ref> The lowered husk damage aids in lautering among other things (see below). The double crush also more fully separates the husk from the starch. The downsides to 3-roller mills are that more power (torque) is typically required to drive them and they are generally more expensive. 2-roller mills are more budget friendly. | *'''3-roller vs 2-roller''' - In a 3-roller mill, the grain is pre-crushed in the gap between the top two rollers, and then the grain flows into the gap between the drive roller and bottom roller, crushing it further.
