Going to be doing some one gallon batches for the first time and I'm not sure how much head space I need to leave. I filled a jug with one gallon of water to see where that puts me and it looks pretty darn full.
Is that going to be enough space or should I go a bit lower? I will be picking up some fermcap from my LHBS if they have it, but what would you guys suggest as space needed with and without fermcap?
