damn it. i set aside my pilsner i brewed today about 5 hours ago in the garage to really hit pitching temp. i go back in just now and see that the stupid rubber bung has POPPED off again. (it pops off due to temp change/air pressure IDK) this happened a few months ago too on one batch. its only one out of the 3 bungs i have that does this. 4 hours in a somewhat messy garage with no lid. that is really annoying. ill have to tape it on or something in the future.
not happy about that.
