Hi there!
I used to bath sparge with a cooler and copper manifold with an efficiency around 75%. I moved over to a 10gal SS Brewtech mashtun and my efficacy moved up to 80%.
Now Im using the SS Brewtech tun within a 3 vessel HERMS system (HLT,MLT,Boil kettle) and Im getting a brewhouse efficiency of 64%. (my process is pretty much the same as the Electric Brewery)
- The crush has not changed, so I assume thats not the issue.
- I recirculate thru the coil in the HLT for the whole mash time of 1 hour. Recirculation creates a little whirlpool on the top of the grain bed and the bed is not compacted. The wort circulates very well and Im sure that there is no channeling.
- I fly sparge for around 40 minutes. The sparge water flows in slowly, not creating a whirlpool on top of the grain bed. Could channeling be the issue?
I sparge till I have 8 gal in the boil kettle. Should I stop before to have less water in the mash tun?
The volumes are not off. I collect 8 gal pre-boil, 1.5 gal boil off, 6 gal into the fermenter.
I did only measure OG when the boil was over, so I dont know final run off OG.
What do you think?
