I have some problems with my starch conversions and think there might be two possible problems. I mashed in about an hour and a half ago and keep doing iodine tests, but conversion isn't complete. I mashed in and hit my temperatures almost exactly, so mash temp isn't the problem.
I have narrowed it down to two variables, first possiblity is that my grain got cooked in the back seat of my car and second is that I have bad iodine. I purchased the grain at my lhbs on friday after work and let it sit in the back seat of my car till this morning essentially letting it bake in the 120 degree heat inside the car all day yesterday. The other is that I have bad iodine, which I left sitting out in the sun for a day and a half last time I brewed.
I don't know what to do in this situation, but if it doesn't convert in the next 30 minutes I am going to mash out anyway and just brew as normal. Is it possible that the heat inside my car denatured the enzymes in this grain, or am I just being paranoid.
