I brewed up a Lake Walk Pale Ale today, and used my new rectangular mashtun. It didn't hold heat very well at all--I probably lost 5-8 degrees in a 90 minute mash. So if I started at 152 and it eventually went down to 145ish, I realize it will be a highly fermentable batch and it will be pretty thin in regards to body.. No big deal. My question is without PH paper, how can I be sure it converted? I did a iodine tincture test and it didn't change, which indicates no starches left. So, I assume it converted. If it didn't what would be my indicator? Terrible efficiency?
FWIW, I calculated 1.052 which gets me into the 72% range.
My assumption is if the mash didn't convert it would be really low, right?
