We brewed 10 gallons of an extract wheat kit we got from our local HBS, and have been sampling it for a while in fermentation and in the keg and is tastes very chemically. We brewed two other all grain batches that day and they both turned out great. What could have happened? Could it be bad extract? BUT most importantly how do we salvage the 10 gallons? it's border line undrinkable. I can have a few toward the end of the night. would dry hopping over come some of the taste?
