Sorry to hear that the grapes died; it’s always wise to consider zone hardiness. Yo have a point about our not noting the zones for the varieties named and we’ll look into that; be assured that there are far more varieties than are named here—and that can be named here. For that reason, we advise you to consult a cooperative extension for more local guidance; find your state here and make contact with the nearest extension service as directed.
It may be more than the variety/zone hardiness that is at issue. Often soil quality, moisture, and disease are involved, too.
