In my continued efforts to completely understand my system I've reached a new roadblock I was wondering if any had any experience of.
So - I have been calculating my boil-off rate based on the difference between volumes going into the kettle & into the fermenter (accounting for kettle dead space & hop absorption). However, the difference between my pre-boil OG & my post-boil OG (both temperature adjusted) is pretty different to what my pre-boil & fermenter volumes would imply.
My real questions are;
- Does the time to get to boil affect amount of volume lost without affecting OG, i.e. doesnt concentrate the wort?
- Does the intensity of the boil effect how much of the volume loss contributes to OG increase, or does all volume loss always cause increase in OG?
- Does volume loss during cooling contribute to increased OG?
Appreciate any advice
