So I'm at work just a bit ago putting stuff up in the stockroom when a box comes apart on me and a bunch of half gallon bottles of store brand lemonade go on the floor. Was initially relieved that none of the caps broke off but then noticed one bottle had swollen up and no longer resembled a rectangular juice bottle (think OceanSpray) but a 2 liter pop/soda bottle and fizz was seeping from the cap. Got it over a trash bin and carefully and slowly undid the cap to release the pressure. Once I got it open there was the unmistakable aroma, it smelled like beer! Still has a few months to the sell-by date but that sucker had fermented. I poured it out but then wondered if I should have given it a taste first just to see what it was like. Got me thinking though what's the craziest thing you've tried fermenting, either on purpose or by accident, that you actually thought tasted pretty good?
