I'm planting 3 grape plants this spring. I've already planted a red
variety, and was wondering if anyone could suggest a white/green
variety, as well as a purple or dark blue variety. Basically, I'm
wanting to do the red, white and blue thing.

I'm interested in:

1) disease resistance
2) productivity
3) excellent flavor for fresh eating
4) early and mid season harvest (already have late covered with
the selection of Catawba)

My grandparents had a white grape that was very sweet with a pungent,
spicy flavor. I loved that, but they could never remember what it was.
Of course, it never produced a whole lot, so I suppose even if I knew
what it was, I shouldn't really consider it. :-(
