Harsh taste

[mattsearle]

I had a harsh/ bitter "bite" on 4 or 5 beers in a row several years ago and couldn't pin it down to anything no matter what I brewed.

Eventually a professional brewer tried a bottle and suggested a possible minor infection, so I changed out my plastic fermenters and any plastic hoses etc for new (basically anything that wasn't stainless was thrown away) and I never had it come up again, so this appeared to be the issue in my case.

From My first infected batch

I ask as a few years ago I purchased a Blichmann 14 gallon conical from another brewer. The brewer was honest in admitting his last several batches were infected. Arriving home I disassemble everything and I mean everything. The nylon barb on the ball valve is green/black with mold! Clean everything thoroughly and replace the da*n nylon barb with stainless. I've since fermented several batches in the Blichmann without issues (or souring or infection).
