Ok, I'm having some new issues. The past two batches I have made have had this plastic taste to them! Not good at all! I'm practicing the exact sanitation techniques, same temps ect. My FC is always at 62 degrees, and I'm brewing the same way I have for a long time. However, the past two brews have tasted just horrible, with a weird plastic taste. I know my mash temps shouldn't be an issue. I taste it before I keg it and it has the same taste, so it shouldn't be the keg. It was in a better bottle with no blow off, so it rules that out. What is this problem? I'm REALLY getting tired of pouring beer down the drain! Any help would be great! Thanks!
