couple of questions danestead, would love to give this a crack, but as its a bit of an outlay for ingredients I don't want to do it half a$$ed.
I BIAB no chill, but could attempt to cool the wort with ice bags etc. and ditch the no chill if you think it will make a difference?
is your end volume 25l?
as opposed to the various stages you mash at, could I just go 90 mins at 66 degrees for example?
is 90 min mash essential?
is adjusting water profile essential? as I have never paid much any attention to this before.
as I said happy to do the hard yards, just probably limited with my equipment is all.
