So a few friends and I brewed the same beer and put it in a barrel to age it. Well it turned sour. I ended up bottling it and it actually has become pretty tasty. One of the guys aged his on cherries and it scored very well in a competition. Well theyve been in the bottle for about 1.5 years (always in a Rubbermaid tote, but carbonation has been stable) and I just noticed that on the surface of the beer in the bottle, there is, what I assume to be, mold. Its not much, just a few spots, but its in every bottle I have. Its entirely likely that its been there for a while and Ive drank it before with seemingly no ill effects. So can I continue to drink these?
