OK so, Ive been brewing for four years, have dozens of all-grain batches under my belt, and I've never had a mash that didn't convert. Until tonight.
The grainbill was simple: 10 lbs Marris Otter; half pound Victory, half pound wheat. Dough in at 165, stirred a bunch, temp stabilized at 152. After 45 minutes, I came back to heat my sparge water, and did the iodine check. It was solid black. I mean, Solid. Black. WTF??
A half hour later, still black. After 2.5 hours mashing, the iodine showed brown and black mixed. It's too late to brew now, the whole schedule is impossibly messed up. I'm going to let it sit overnight, but my gut feeling is that I'll be dumping the batch and getting new grain.
The grain was purchased at my LHBS on Saturday, ground there, brought home to brew.
Anyone ever seen anything like this? I am at a loss.
