I have noticed the last few batches I have made have come in way under expected final gravity. For example, I just finished an amber ale, final gravity was expected at 1.014 come in at 1.008. Looking over my notes from several others I see a similar trend anywhere from .004 to .006 lower than expected. Am I doing something wrong?
UPDATE:
I have gone over my notes for my last 15 batches, and have found than all but one was under the estimated final gravity..... The one that was over was a milk stout that I assumed I had too much lactose in. So, it seems that I have yet to get close to any final gravity expectation.
