Not sure if this belongs here or in software, move if necessary.
I have a bottom drain keggle with a jaybird false bottom. I have 1 gallon underneath the false bottom, which I guess is referred to as slack space. I 100% recover all this volume. There is no option for this configuration and I was wondering how other deal with it. The problem arises when calculating grain to water ratio. Only the volume above the false bottom is used. However, when calculating strike temperature, the entire volume is used or your strike temp will be too high
I saw a couple of older threads but none of them had any real solutions. Right now I am adding 1 gallon to the mash (to get 1.25 ratio) and then subtracting 1 gallon from sparge. This works ok for my mash thickness but my temps are always off since I'm adding more water. I just started using a HERMS so I usually start recirculation around the 15min mark.
