I've brewed the same Bitter and ESB recipes about 5 times each and have all turned out great. The last two batches of each have turned out with what can best be explained as a sweaty sock aroma. On a couple of occasions the smell has lessened after a couple of weeks of keg carbonation. Two batches refuse to let go of the smell.
I have temperature regulated fridges. I have always sanitized religiously. What could be the culprit?
I buy grain in bulk. Could this have aged? It's at most been open 3 months but has been stored in high a humidity environment. All my hops are vacuum sealed after use.
My last few brews needed excessive stirring to dough in. Would additional oxygen added during the stirring be a factor?
Last point, for giggles in my last few brews I drained wort from the MLT to gallon milk cartons to measure volume collected. I normally pump from MLT to BK. Any chance that this has had an effect?
Cheers
