Failed to burp my growlers and my 1 gallon exploded during second fermentation. Fortunately, I keep them in a plastic tub in the basement, so the mess was contained.

Underestimated the effect of elevated outside and thus room temperature and got very close to making vinegar.

I barged in here just based on the title, all ready to open up about my failures in life. Then I read the post text about brewing a batch and got very confused, and only then realized which community this is.

I've been busy with other hobbies.... I wonder how moldy by 1 months brew is right now.
