Anyone ever have problems with inexplicably low original gravities? With my last 3 batches, the gravity has been coming up 25%-50% short. (My expectations are based on appendix 11 of the 3rd edition of the Complete Joy of Homebrewing). Obviously, I can just add some more fermentables to get the gravity I want, but I'd like to find out what's causing the problem.
Relevant Details:
I usually boil about 2.5 gallons for a 5 gallon batch;
I mix and aerate the wort before taking a sample;
My samples are usually around 70 degrees when I take a reading, and I adjust the reading accordingly;
I've checked the hydrometer, and it's fine;
I've had this problem with both LME and DME;
These have been all extract, so the answer can't be that I'm messing up the mash;
Again, I realize that this isn't hard to remedy, but does anyone have any suggestions for why I might have this problem now? All of my batches before these last three have been pretty much right on.
Thanks for any suggestions, I appreciate any advice.
Cheers!
