I've started my very first batch of cider, in a 3 gallon carboy. I have a commercial stopper and airlock, and two questions.
1 - how much headspace is required for primary fermentation in a glass carboy? I left just a few inches.
2 - when installing the airlock, how much water are you supposed to add to the airlock? does it have to be sanitary water/vodka?
Thanks
