I was hoping I could get some feedback on how I take my volume readings.
I have a 10Gal kettle with volume markings on the inside that I put on and are very accurate.
I use a 0.08Gal water/lb grain absorption ratio and a 1.6Gal/Hr boil off rate (which fluctuates widely and is very annoying).
After mash is complete, I squeeze the bag and get the kettle volume to 7.1gallons (5.5 into fermenter + 1.6 boil off). I am not compensating for heat expansion. Should I be? If the kettle says 7.1Gal after mash, what should I use for pre-boil volume? 7.1 or take into account heat expansion?
Post-boil, I base the final volume off of the cooled wort in the kettle. I do not whirpool and leave material behind in the kettle, everything goes into fermenter. I found when I tried to whirlpool that it didn't really do anything, it didn't make a cone and just fell flat. When transferring to the fermenter, I don't know when to stop transferring the gunk. I've read the articles saying that excess trub in the fermenter doesn't make a major impact on the final beer so I just dump it all...
So, I'm making these numbers up, let's say an inch of trub in the fermenter is equal to .5 gallons of volume. When I get my "volume into primary" for efficiency calculations, should I account for the trub taking up volume? So, for example, if the volume in the kettle is exactly 5.5 gallons and I dump everything into primary, isn't the true volume something less than 5.5?
