What temperature does beersmith assume the wort temperature is when calculating the pre-boil volume? I know there is the cooling shrinkage adjustment for post boil in the equipment profile, but does that affect the preboil as well? My wort is usually around 170 degrees F when I measure the pre-boil volume (with a stick that was calibrated at room temperature). At that temperature, water takes up about 2.4% more space (volume) than it does at 70 degrees F (See https://www.engineeringtoolbox.com/water-specific-volume-weight-d_661.html ). Should I be mentally adjusting the preboil volume for that 2.4% difference? I realize with 5 gallon batches this is a very tiny difference, but once you get larger it starts to make a noticeable difference. We are using beersmith with a 3bbl and 20bbl brewhouse, would like to get accurate efficiency numbers.
I have read both of these threads and neither give a definite answer. It would be nice if beersmith had a user definable setting for what temperature the pre boil measurement was taken at.
