The first batch of this that I brewed back in April was not only too low in FG (1.040) and too high in IBU (~32) but also ended up with some sort of infection while conditioning in the carboy. By the time I noticed it, however, it had already formed a nice pellicle and didn't have any off smells so I decided to just let it ride (for the past 7 months).
Tasted a small sample over the weekend and it's turned into a pretty decent (accidental) sour, with a nice golden-brownish color. Maybe some sort of Münster Alt?
Anyway, I'm slowly lowering the temp on it (along with a schwarzbier) in my lagering fridge and hoping to get the pellicle to drop. Hoping to bottle this weekend or next.
