I just racked an all juice cherry cyser from primary to secondary and it has about a 1/4 to 1/2 gallon of empty headspace. Should I top it up with to 5 gallons, if so should i use cherry juice, apple juice, or water? The mead did stop fermenting high at 1.040 from 1.120 if that makes a difference on what to top off with.
Thanks
