Has anyone made the final conclusion when to pitch the glucoamylase? I think even the style originator is not certain of the perfect time. My SEBAmyl-GL says the product may denature if over 148F, so this is right about where I want to mash for a single infusion. I could certainly add during the mash with the risk of being at the edge of denaturing, and I also considered adding the enzyme after the boil and when I was cooling with the IC to go into fermenter. If 135F was the time of addition, the enzyme wont denature since the boil is done, but may not be super active due to the low temps below optimum in the FV.
So, with that said, when should I add enzymes....during mash, after the boil at 135F or BOTH?
