To preface, I mash and batch sparge in a cooler, move it to a kettle, and then siphon into my fermenter after boiling and cooling.
I brewed a week ago and there was a significant amount of trub left over in my kettle after transferring. That isn't anything new; however, I haven't been diligent in keeping up with those details in BeerSmith. So, I check what I have in my equipment profile and under Loss to Trub and Chiller, its set to 0.1 gal. I bump it up to 0.35 gal and check one of my recipes to see how it affected my numbers.
The IBU's went down a few, which I expected, and to compensate for the volume loss to trub, my sparge volume increased. The thing I don't understand is why the estimated original gravity didn't go down, it stayed the same. Since I'm adding more water, wouldn't I be diluting my wort and lowering the expected gravity? Am I missing something here?
