Doesn't matter what you do to Stone's GG wine - instant hangover for anyone over 18. Doesn't matter what you mix it with either. Have written myself off far too many times in my yoof on that shit. Made from hospital grade brandy and offcuts from the glace ginger industry. And hospital grade brandy is distilled grape stalks and seeds and only good for disinfectant. Granted it's quite good disinfectant.
EDIT for l'esprit d'escalier - think of the above as chocolate/orange flavored Handy Andy.
IIRC it was about 2 tsp choc, a dash of hot water to melt it and a shot of cointreau, possibly topped off with soy or milk. It was not a professional shot but more of a stoned bartender creation in a bar with a very limited range - Meyers Place.
But choc and orange, it's not rocket science, you're a capable person.
