Actually..... here would be something interesting.
Cannabis is soluble in alcohol, period. That means that if you put x amount weed in 1 fifth of everclear, and x amount of weed in 2 fifths of vodka; it would essentially extract the same amount of thc, one would just be more dilluted. So, wine would still extract thc(wine has what 12-14% alc), the result just obviously wouldn't be as potent as green dragon made with everclear.

So if he likes his wine, and doesn't mind drinking a couple glasses to feel the effects, then why not. I'd use KB though, I wouldn't ruin good wine's taste with shwag. Think about seeping some Juicy Fruit into a good fruity wine. I think I'd like that.

Make sure it's airtight though. That would reduce the chances of it turning to vinegar, that would be bad.
