Ignore my earlier OG estimate. I misread your first post. I thought it said "total of 5 gallons".
You can estimate gravities before you add all the water. Honey averages about 36 points of gravity per lb. Twelve pounds of honey would contain approx 432 points (12 x 36 = 432) Just divide 432 by batch size (432 / 6 = 72 or 1.072 estimated OG)
