I recently brewed a Hefeweizen via BIAB (Ed Worts recipe). The bulk of the grist was wheat so I asked the HBS (online) to run it through their mill twice (they said their mill was set to .045). When I received the grains, they still did not look crushed enough so I used my kitchen food processor to further grind it up. Putting 3 or 4 scoops in at a time I hit the pulse button a few times. The result was definitely a finer crush. Not as far as flour but chopped pretty fine with maybe 20% as fine as sand. Other than wheat, the only other grain was pilsner which I also ran through the processor.
Beersmith said that my OG should have been 1.054. My actual OG came in at 1.037. All my other numbers such as water and mash volumes were spot on and my FG came in right where expected at 1.013. The only other thing I did different is that I added 1/2 lb rice hulls. Even though I BIAB I was thinking that maybe the rice hulls would improve the drainage from the bag.
Any thoughts on what may have caused the low OG? Any reason it might have been caused by running the grains through the food processor or the addition of the rice hulls?
Thanks, Mike
