I'd have got a little more! It's like hen's teeth round here. I made a gallon from Welches' purple grape a few months back. It is now just about drinkable. I suppose you could use 2lt grape and 2lt apple juice. Add the honey and sugar up to you desired SG.

I wouldn't add malic acid but maybe a tannin and citric acid but I'm fairly new so someone else might be able to help more.
I am almost certain you'll need the nutrient.

Definitely some tannin, and fill the rest of the gallon with more juice, apple or grape, or whatever you fancy really.
Look at the packs, see how much sugar you have, add enough to get the ABV you want.
Rule of thumb 20g/l=1% or 100g/4.5l=1%, this rule tends to be a little bit high once you multiply it up to about 14%
