It was made by Gallo, I think, a fortified grape wine. I bet if you made a batch of 14% concord, fortified to 17% and backsweetened to at least 1.006, maybe 1.010 you would be successful. Easy to make, grab a gallon of Concord or 3-4 frozen concentrates, sugar to hit target SG and off you go (after adding nutrient, tannin, pectic enzyme, etc). Hit it with a blend of tartaric/malic acid if need be.
I recall, as a child, for my birthday when I was maybe eight, asking for pizza from a local pizza place and some Ripple. My parents granted my wish, even took me to liquor store to pick it out, or change my mind. I was served about half an ounce of wine that my Mom had diluted with Concord. But in all truth I was more of a Mogan David birthday girl back then, took a walk on the wild side with Ripple. I had wine on every childhood birthday I can recall, and I still do--guess I am a lifelong wino!?!
