I did a five gal batch of unicorn blood recipe. Closed it with airlock. Was bubbling like crazy and then I woke up this morning and it looks like the cider came up through the airlock and it overflowed a lil on to top of bucket. I started it on Wednesday. I'm guessing I didn't leaving enough head space. What should I do and is it ruined? Or should I just leave it and let it run its course?
