I plan to try Graff for the first time and I'm going to do a 5 gallon batch.... But all my carboys are 6.5 gallons.... That's going to leave me with quite a bit of headspace.
The guy at the brew store once told me too much headspace is not good... What should I do, just do it with a gallon and a half of head space or try to calculate the 5 gallon recipe into 6.5?
Carboy1: Hopped Cider
Carboy3: Seasonal Cider
Bottled: Cream Soda
Still On Deck: Graff Cider
