jlevac Posted September 14, 2012 Share Posted September 14, 2012 Maybe this is an equipment topic but it involves milling. Coming from the brewing side of things, when we mill our malt for distillling, does it have to be a finer grain size than beer grain? Would I be able to use a beer grain mill spacing or do I need closer spacing? Newbie question Link to comment Share on other sites More sharing options...

John McKee Posted September 14, 2012 Share Posted September 14, 2012 Justin Aden from Michigan State gave a presentation at the ADI conference last year that suggested a sizable increase in yield due to using ground flour. The idea was that a greater cracking of the grain allowed a greater access to the starches --> higher yield in alcohol. Link to comment Share on other sites More sharing options...
Denver Distiller Posted September 14, 2012 Share Posted September 14, 2012 That's called "Fine Grind-Coarse Grind Difference'. Jlevac, if you look at a malt spec sheet, you should find FG/CG difference listed. That will tell you the improvement in yield between hammer milling your malt rather than running it through a 2, 4, or 6 row mill. You'll normally pick up a percentage point or two in most base malts via hammer mill. Cheers Link to comment Share on other sites More sharing options...
PeteB Posted September 15, 2012 Share Posted September 15, 2012 If you are lautering as I assume you did with beer, you will need to keep grinding to somewhere near beer size, but if you are fermenting "grains in" it appears the finer the better See previous discussion on this subject http://adiforums.com/index.php?showtopic=2193&hl= Link to comment Share on other sites More sharing options...
