About 12 days into my primary fermentation my two year old managed to wrestle the air lock free of the stopper. The stopper remained in place in the throat of the carboy. It remained like this from anywhere from 1 to 24 hours. When I discovered it, I promptly replaced the airlock and refilled it with sanitizer. Does anyone anticipate any major problems? The beer is a Brewer's Best Dunkelwiesen kit.
