I haven't made this particular kit, but when I think Zinfandel, I don't think heavy oak bombs, I think a lighter, maybe fruity, jammy kind of taste with a hint of oak. So if I were to make it, after a few months of bulk aging, I would taste it and make the determination based on what I think of a Zinfandel. I might end up adding some oak for a bit, but it would probably be a French Oak medium toast or a mixture of French and American.
