Missed mash temp, so I draw off a portion (not all) of strike water from mash tun. I heat it to 200-210 and replace to bring temp up. Is this denaturing the enzymes I need for starch conversation? Any ideas?
Apologies to the OP, this thread went off topic. If i understand your process, you mash, show starch conversion with Iodine, check your gravity, and it is low, you draw off some of the water (wort) and bring it up to just below boil temp, add it back to the mash.... you've done this twice. My question is did you see a difference in your efficiency? Denaturing enzymes is beyond me. I think of it as a PH + Temp thing but maybe someone has a better answer.
