THREE GALLONS OF HONEY???!!!
In one batch???
What kind of SUPER-mead are you making? All I've ever used was 1 gal or less for a 5 gal batch.
For 1 gal, which is about 12.4 lbs, you can make several great batches. I have one (6.5 gals) going right now.
I recommend you split them up into 1 gal batches (use growlers or fruit juice containers) after the primary fermentation. Add the fruit to the secondary. This way you can end up with 5 different flavors from 1 batch.
From there, actually about 1 year later, you can determine which one(s) you liked best and make full batches of that flavor.
