I have never made one from the leaves Archie so I don't know about that, but you should be able to have some grapes before another three years. I don't recall the varieties you planted, but if they are hybrids you could keep a few next year and a fair crop in the third year, with pretty close to a full crop the fourth year. As long as your growth was good this year, you should have a very healthy vine next year. If it is good and vigorous, you can leave a few clusters per vine to help hold the vine in check.
I hope someone has tried grape leaf wine and can give you a recipe.
By the way Happy Belated Birthday. I knew I should wish you a Happy Birthday on the 16th, but you hadn't checked in for a while. Good hearing from you!
