I’ve been meaning to write a short product review/endorsement for Monster Mill’s MM-2 since I’ve first used it. These are fantastic mills, and make lessor mills (i.e. mills with smaller diameter rollers) feel like toys in comparison! Grain mills are simple tools, and this one does its job quicker and more consistently than any other I’ve tried.
The MM-2 is equipped with 2 rollers, 1.5″ in diameter. These rollers are significantly larger than most competing grain mills. A larger diameter roller means a couple things. For one, the mill is able to pull malt more effectively for wider range of milling gaps. If you are using a mill with small rollers and are trying to obtain a fine crush (perhaps you are a BIABer), you’ve probably noticed your mill spinning while processing little to no malt at times – incredibly frustrating. Not only does this lengthen the milling process considerably, but your mill is probably chewing up grain husks in its failed attempts to pull the grain through.
Secondly, larger diameter rollers allow you to achieve a more consistent crush at a wider milling gap compared to mills equipped with smaller rollers. By more consistent crush, I mean rather than having a mix of inadequately crushed, excessively crushed, and ideally crushed malt, a greater proportion of your crush will fall into the “ideal” category. I will say that I have had good results with crush consistency by reducing the milling gap and hydrating malt at 2% moisture content with my previous mill, but this adds time to the milling process – especially as it can be difficult for a small mill to pull grain through at fine crush settings (see paragraph 2).
Anyways. I’m very pleased with my MM-2. I’ve had for about 6 months now. As my brewery continues to evolve in the years to come, I’m positive the MM-2 will remain a constant.
