    Weird mash-in mistake - unmilled grain

    So, somewhere between the mill and the mash tun, my grain bill picked up an extra bucket of unmilled Ashburn Mild. It seems it was in a bin that the mill fed into. I can't imagine I pulled much sugar out of it, but I wonder if I'm going to pick up more non-fermentables. Any thoughts? (the extra was about 15% of what ended up being the total grain bill)

    I doubt you will get anything from it at all, no worries.

    Thanks for the feedback. I was leaning that way, too. It's just something I'd never considered a possibility until I saw someone cleaning out a bin that was labeled for storage... Oh well. Thats what inaugural batches are for right - finding the kinks that need to be worked out. I figure if that's the worst thing that happened, we're doing pretty well!

    Unconverted starch carryover would be my concern.

    Have you tried an iodine check of your wort/ferment?

    Pax.

    You may also get some extra tannins and polyphenols from the husk of your unmilled grain.

    Wouldn't that husk be in the mash had the grain been milled?

    And I don't know that you would get any extraction from the unmilled malts at all, but I would presume that if you did; there would have been enough diastatic enzyme to take care of any conversion of starches you may have extracted.

    Yes, that husk would be in the mash had the grain been milled. But there was 15% EXTRA grain added that was not milled. Therefore, there was 15% more husk in the mash than planned, and as such a higher level of tannins and polyphenols.
