I brewed a fairly big English ale, around 8% sometime over the night, the vigorous fermentation blew the blow off tube clean off of the top of the carboy. Aside from a huge mess, my brew was unprotected by an airlock for I'm not sure how long. It is in a fridge and it smelled fine in there. Still bubbling like crazy with a monster kreusen at the top. Has anyone had this happen and did their beer get contaminated?
