I am making two separate gallons of mead. Each batch used 2 1/2 lbs of honey (I wanted a drier mead). I used K1V-1116 yeast, one packet divided between the two gallons. It was re-hydrated in warm water for 15 minutes. In one of the gallons I added about 15 or so raisins. In the other gallon I added 15 raisins, one whole orange including rind and 1 teaspoon of coriander. I shook each gallon for about 10 minutes to aerate. Airlock on each gallon. I Did not take any specific gravity readings because I don't really care what the abv is ( I realize there are other reasons to take sg but....eh). Fermentation looks active and healthy. I plan to rack into clean gallon jugs in three weeks or so (being careful not to oxygenate the must). So now comes the question. In the orange/corriander (but question can pertain to both gallons) the orange takes up a lot of volume. I also suspect that when I rack it that a lot of liquid will be bound up in the orange itself. I would like to top off the jugs to reduce airspace but also to increase my yield of yummy goodness. As stated, I'm not concerned about abv and I want a dry mead (but I don't mind if it turns out sweet either) but I don't want watery mead, so what can I top off with? Orange juice? Apple juice? water? or honey water? Any help or advice would be appreciated. Oh yeah, while I'm add it, should I add fermaid K at the racking?
