I have a Spike HERMs system and have been very happy to date. I have developed a mash schedule that works well for me. I was surprised to see the Spike website suggests a completely different method than what I was doing and I would like some opinions on the matter.
I set my HLT maybe 5 degrees above strike temp and run both the HERMs coil pump and the HLT recirculating pump wide open until I reach strike temp in the mash tun. I then turn off the mash/HERMS pump and dough in. I then add cold filtered water to the HLT to bring it down to maybe 2 degrees above target mash temp. I then turn the pump back on. I run the pumps the entire mash.
The rec on the Spike page says to set the HLT at 180 degrees and only turn on pump every 10 minutes briefly to keep mash temp where you want it.
I know this goes back to the qestions regarding protein shear from pumps, but I have never seen a reccomendation to use a HERMs system in a fashion without constant recirculation. Does anyone else share my concern of exposure of mash to such high temps and creating large amounts of unfermentables and resultant poor attenuation?
What does everyone else do?
