Also when did you put your LME in the beer? Adding LME at the end of the boil will have huge positive effects on your beer. We are currently validating in store putting LME in after the boil. Since you only need to sanitize it, our theory is that if we keep it above 160F for 15 minutes we will be fine. So far we have had luck at keeping LME above 180 for 30 minutes with no problem. Just some food for thought.
I may have to try that. For both batches, the one with the old LME and the subsequent one with the DME, we added the extract after removing the steeping grains (at about 160F). The heat was off and we stirred them in well before ramping up to boiling. The DME batch smelled like normal all grain wort, whereas the LME batch had that molasses aroma and was much darker than expected.
Not trying to knock Morebeer. I've been very pleased with them over the years. Just a bad batch of extract, I guess.
