Water Absorption different for AG Wheat & Barley?
« on: December 20, 2014, 05:28:29 PM »
Doing a Gratzer using 8lbs wheat, 4oz. acid malt and a lb of rice hulls. I understand wheat malt absorbs less liquor than barley but does the 11% rice hulls added nullify any meaningful difference?
Using promash my grain absorption rate is .13% and is pretty accurate on my system for most batches, so i was wondering if i should adjust for a mostly Wheat malt recipe. Thanks

I did a Graetzer and really didn't notice much difference in water required, but I did use rice hulls.

You could do a mini-mash, lauter, and see what the wheat weighs when done. Report back so we all learn something!

Well, i found when adding rice hulls, i got the same absorption as if it was all barley. case closed.
