Dont know if you have started this batch yet but here is what i did for my Raspberry Melomel in 07 and it was awesome.
Raspberry Melomel
6 gallon batch
21 lbs of Fresh Raspberries from parents garden
15 lbs of honey (BJ's Brand), Local honey would probably be even better but this came out awesome.
3 32 oz. bottles of Pure Raspberry juice from nature with no meta or sorbate in it.
6 tsps. of nutrient - 1/3 at start, 1/3 at 1.065, and the last 1/3 at 1.030.
3 tsps. of energizer
Water to 6 1/2 gallon mark.
pectic enzyme per manufacturers recomm. (I used the liquid concentrate)
No acid as it was for some reason at .75 TA already.
2 sachets of red Star Montrachet yeast as Melomels can typically be troublesome.
Ph 3.4, TA .75
Fermented at 66*
Starting SG was 1.085
I always freeze my fruit for 1 week and then thaw in primary and pour hot water over them.
