I had just bottled my first batch of Apfelwein out of it too! Bummer. I got it used from a guy who used it for wine. Must be a cheapo. It is smooth all over (no ridges like my other one).
Ok, I've got a crack myself, in my carboy that is. Looks like where a rock hits your windshield. This is the first time I've noticed it and I'm not sure how it happened? Maybe I bumped it with my other carboy?
What do you think? Tape it or trash it?
