Started my 1st mead 2/3/23 with an OG of 1.110 using 3 lb local Idaho honey. Racked to secondary yesterday FG 1.010 because I am going out of town and didn't want to leave it in a bucket since I was beginning to see yeast rafts and was worried a film yeast might take over. I have this much headspace in my 1 gallon DJ. How do you top up a mead? I don't want to use just water, or change the flavor with wine which is all I have in the house. I have this grocery store honey I could use but am uncertain how to go about it. All advice will be appreciated.
