I make something similar.
I use Realemon and Realime at a 2:1 ratio. Start with Realemon, SG 1.095, when reaches approx. 1.030 add Realime. Once dry and cleared, rack onto some sort of Old Orchard concentrate, ie: Blueberry/Pomegranate, Strawberry/Kiwi, Cranberry, etc. The possibilities are endless.
