Joe, here is an orange wine recipe from The Art of Making Wine by Stanley Anderson:
"Orange Wine
2 6 oz cans of frozen orange juice (EDIT: per Bernard's comment, this should be frozen concentrate)
1 gallon of warm water
1 orange sliced
1 lb of chopped raisins or 10 oz grape concentrate
1/2 t pectic enzyme
1 campden tablet
2 lbs of sugar
1/2 t yeast nutrient
wine yeast
Starting SG should be 1.090-1.095, acid 0.60%, makes 1 gallon of wine.
Mix all ingredients except wine yeast in primary fermenter. Cover with plastic sheet. Add yeast when must is cool (70-75 F). Stir once daily for 7 days. Siphon into gallon jug and attach fermentation lock. Rack in 3 weeks. Add 1 campden tablet and top up jug (use water if necessary). Rack again in 3 months. When wine is clear and stable, bottle. Age 1 year."
Perhaps you can adapt this to the juice or whatever you have. It appears that he starts with about 1 gallon 12 oz of juice to yield one gallon of wine. Good luck.
