Last night I had a bomber of my batch of Jamal’s Evil Twin (renamed Attacked By Robins), bottled about a month ago. On the inside of the bottle there were a half dozen or so small globs clustered together that looked like - for lack of a better description - black mold.
Can mold form in a bottle while carbing/aging?
Or is it some hop/trub residue that maybe got transferred during bottling?
Bad cleaning/sani job by me?
On the upside, the beer tasted amazing, probably the second best thing I’ve made so far (right behind Dead Ringer). I had tried my Jamal’s Evil Twin early on (10 days in bottle) and it didn’t wow me, but as it’s aged another couple of weeks the difference is night and day. And whatever mold or gunk was in the bottle sure didn’t impact the taste…
