I live in the Catskills, zone 5, and there were several wild grape vines
on the property when I moved in. Up till now I have simply clipped them
back and used the vines for decorative wreaths, because the grapes are
horrendously tart.

What I was wondering is whether it is possible, by feeding and nurture,
to make them produce more palatable fruit?

This kind of question is exactly why the NY Ag. Extension Dept.
was created more than a century ago . . .

The answer is: probably not. Ontario producers fiddled with
native grapes for 50 years before giving up, removing all, and
replanting with French or German vines.
