Hi all.
I have a gluten 40L and cannot get my head around the water volumes. I have tried beer Smith and now Brewfather profiles that others have pulled together.
They are based around roughly 2.7 to 3L per kg of grain, but I always end up with a sg before sparging that seems on target. Then when I sparge with the volume provided by the profiles the sg drops to at least 6 points below expected. If I sparge with less, I get less volume that is more bitter than expected due to the the hops not being adjusted.
My understanding of sparging is that it is rinsing the sugars of the grain and should therefore raise, then dilute the sg.
My mash efficiency appears around 55%. This hasn't changed despite me trying both bought and grain I've cracked myself.
Can anyone help at all?
