Well known, not sure about that but here is an easy go to recipe I use often.
Basically you are fermenting Realemon and Realime juice, then adding a flavored concentrate, ie: Old Orchard, Welchs, etc.
For a 2 gal. batch.
2 gal. water
15 oz. Realemon juice
8 oz. Realime juice (this goes in around 1.020 - 1.030)
2 tsp. nutrient, then step in 1/2 tsp. at 1.070 and 1/2 tsp. at 1.050
Energizer per manufacturers recommendation
1/4 tsp. tannin
Pectic per manufacturers recommendation
Sugar to bring SG to 1.090 - 1.100 (depending on how much alcohol you would like. I usually push mine to 1.095)
Ferment dry, down in the .990's.
Once dry, rack to secondary carboys. Add SuperKleer. It should be crystal clear within a week.
Once clear, add 12oz. concentrate(this may be adjusted to suit your tastes, this is the amount I have settled on), such as Old Orchard Blueberry/Pomegranate, Cranberry, Strawberry/Kiwi, etc. to clean carboys then rack clear lemon/lime fermented liquid on top of it.
From there, you can backsweeten to your liking. For me, I usually add 1/4c sugar per gallon. It makes a semi-sweet finished product. I don't like sweet wines.
Also, at the final stage, I add kmeta and sorbate.
Bottle after a week of backsweetening.
This usually takes 3-4 weeks tops from pitching yeast to bottling.
