I've noticed an odd post boil SG difference depending on when I take my sample. My practice has been to dip a small glass in the BK after the whirl pool, cool it to 70* and take a reading. The last few brew days I've also taken a sample from the fermentor after it has gone through the CFC. I'm getting anywhere from 3 -5 points difference in the readings with them being lower when taken from the fermentor. Is there an explanation for this? Seems odd that the sample from the BK cooled to 70* or immediately run through the CFC to 70* should be different.
