First post....
I just made my third all grain batch yesterday (using rubbermaid coolers for the HLT & Mash Tun and a converted keg for the kettle). The OG pre boil and the OG post boil readings have been nearly identical on each separate batch. I know it is impossible since there is evaporation, added hops, etc. for the post to be the same or less than the pre. Kind of like 2+2=4 but I'm not getting anywhere near 4 in this case.
I have made it a point to thoroughly stir my pre boil and post boil before taking gravity readings. I have used a refractometer and hydrometer for comparison and get the same results (maybe a 2 point difference between the two instruments). When using the hydrometer I have cooled the sample down to about 80 or 85 and do the temperature correction.
The first two batches turned out great (though the final gravity on both was about 4 points lower than target).
I have searched and searched this topic and all I can find is "did you apply a temp. correction factor; did you mix the wort up well enough; etc.?"
What in the heck is going on? Thanks for any help!!!
