Hi all. I brewed a Nukey Brown Ale extract kit back in Oct with S-04 dry yeast. Used a fermentation chamber to keep temps, and sanitation (as always) was top notch through the whole ordeal, meaning the pH of the Star-san solution was checked and everything was sanitized twice before touching cooled wort/beer.
The problem is that It never tasted right, always had a slight Phenolic like taste, almost taste like I used wheat beer yeast, not english ale yeast. Now its gotten pretty bad, though some bottles have been drinkable some not (Will be washing bottles before next use).
I know I pitched yeast a bit warm. Maybe 80-85 degrees at most. I also had it start to rain in the middle of chilling, and maybe I need to figure out a way to chill indoors? I have a home-made copper chiller that sat in the boiling wort for 15 mins. Everything else in the process was fine. Fermentation chamber was set to 66 degrees F, the chamber was moved by family about half way through the secondary, but they would have said something if they knocked the airlock off, and it was still filled with the proper amount of liquid, so I know that didnt cause a problem.
I am about to brew a Kolsch this weekend, and just want to make sure something didn’t go wrong. I have 5 other beers prior to the Brown Ale that all turned out good, so I think it was a combo of pitching warm and probably the rain halfway through chilling/long chilling with ice water batch that might have allowed something in. It also only fermented to 1.018 which was a bit high I think, it was fermenting for 5 weeks, with a very active fermentation for the first 3-4 days.
Thank you for any help!
