Making wine from juice at the store?

Saw a guy on Instagram make wine from store bought juice (one of the 1.89L jugs of like 100% pure grape juice or whatever) and he said it turned out pretty good. Assuming I went over all the measurements of how much extra sugar to add and how much yeast to use, I really want to see what I can make.

Just curious if anybody has tried this and liked it or not?
