Had a crack at a corn AG using my esky mashtun. Won't be doing that again, complete PIA transferring grains and manifold blocking/esky not draining well.
So I have a brew keggle - electric element fitted/drain valve/no false bottom, and was thinking BIAB options, for an all in one vessel heat/mash/ferment.
The process I was thinking, heat water to boiling, add corn and continue heating/boiling for some time to get corn gelatinization.
Cool down, mash in grains, wait for mash to finish, cool down, pitch yeast ferment.
Now, I suspect that BIAB is not entirely feasible
1) stirring might be problematic -> tearing the fabric, bag comes loose and everything ends up inside.
2) if the bag touches the element whilst heating, it is likely to melt/burn.
Then I thought, what if some stainless mesh was installed above the element. It would solve 2)
and might allow doing away with bag entirely as larger corn solids won't go thru the screen.
Thoughts/opinions ?
Wonder what a sheet costs:-
