Hi all - I've got a question for you! I've got a few batches under my belt using my new Spike 20 gallon eHerms turnkey system (after brewing on a propane-fired half barrel RIMS for the past 20 years). It hasn't been too bad of a learning curve, though I have one main concern - if I run the wort through the HEX throughout the mash, I've got to set the HLT temp to around 10 degrees warmer than my desired mash temp. I've checked the wort re-entering the mash, and sure enough for a 152 mash it's around 162.
If I do this recirc right from the start, aren't I denaturing the enzymes by raising their temp that much?
