At this point I feel as though I want to give up and throw in the towel. All but two of my batches have ended up with the same, nearly undrinkable off flavor. To me it tastes plastic/medicinal . . . my wife says it tastes soapy but in either case every beer ends up tasting the same after about the 3 week mark. Straight out of the fermentor my last few batches have tasted pretty good. But given time they all degrade into the same flavor.
So far I have been doing extract batches. My fermentation is temperature controlled and I am pretty meticulous with cleaning and sanitation. According to my local water reports my tap water has chlorine/chloramines in it. So after finding this out I treated all my water with Camden tablets. No dice. Same ruining off flavor. OK so maybe the Camden wasn't working correctly I thought. Next batch I use all distilled water. Errr wrong after 3 weeks same flavor.
Next thought was maybe there was some bacteria or such in either my auto siphon,hoses or bottle filler. I clean them all extra thorough and my next batch is a cider. Turns out great! Problem solved!
Nope, brew up the next batch tastes great as its coming out of the fermentor and now . . . yep you guessed it same plastic/medicinal flavor that masks everything else.
I don't know what to do and feel like giving up at this point. This forum is awesome and I would love any advice that anyone has as to what is going on and how I can fix it.
