Im using BIAB and sparge the remainder of my pre boil volume into my wort. When I take my measurements to calculate effeciency do I measure gravity before I sparge to my pre boil volume or after?

There is mash efficiency which is determined after the complete mash and collection of total pre boil runnings and then brew house efficiency which is what the final product achieves after the beer is ready to package
tre9er said:Actually, mash efficiency is determined by first runnings. Lauter efficiency is taken by sparge runnings and the preboil would then be the mash/lauter efficiency (combined).
Thanks, you are correct, I've always just considered it to essentially be one process of mash and Lauter since the pre-boil gravity is what I really pay attention to
tre9er said:Every now and then it's nice to know them separately. You might be getting great mash efficiency (via stirring, good crush, good PH, etc.) but then bad lauter efficiency, and that can key you in on things to improve when you sparge.
Absolutely and I did not mean I pay no attention to it I've been using my set up for so long and have consistently been operating at 82% which I am very content with that I really haven't had any problems that I have to worry about,
