I've heard that grapes bear only on the canes that are more than a year
old, so even if the plant did survive heavy-handed pruning, you might not
see it fruiting for a couple of years.

How about subjecting just just one trunk to your drastic pruning this year,
and see how it goes? You can hit the others in later years if your trial
seems successful. There is a group sci.agriculture where you might find
people with grape-vine experience.
