I got a batch of skeeter pee all mixed up and ready to go, all ingredients mixed in but not the yeast. Was planning to leave it for the 48 hrs, but forgot about it for 5 or 6 days. Went back to check on it and add the yeast but it was already fermenting away! Kind of surprised it could ferment with out adding any yeast! Is it going to be ruined? I sprinkled in a bag of yeast anyway and we'll see what happens. Anybody have some ideas why this might happen?
