I meant zero setup effort!
But I have that now!
No sparge is an issue for me, what efficiency do you see with that? 55% or so?
I just did a couple no sparge batches of my Am. mild. Efficiency in the upper 70s.
Why would absorption rate be lower? Do you mean qts/lb or something else? The grain should absorb the same volume of water per pound of grain assuming complete saturation no matter the mash ratio.
