I am currently brewing a batch of cider. I had started the batch in a PETE (Polyethylene terephthalate) carboy, but a few days later I found it had acquired a strange smell and taste. I felt kind of stoned when i tasted some, and it had a strange aftertaste that I can't quite put. It's definately not an infection or a result of the yeast. Plus the sharp apple nose is more rounded and the flavor more muted. Is this from the plastic? I transfered it to a glass carboy, will the flavor stay or will it (hopefully) fade out?
