You might want to Google search for a primer on this. I let mine grow wild with no pruning and they seem to produce just fine, even though I have to climb ladders to pick them from vines that have climbed into the trees. My neighbor trellises his vines and prunes them quite aggressively. Grapes like a lot of sun, and since we are so far north, he keeps the trees cut back so they won't shade the grapes, and he prunes the vines so that each one only has four "arms" - two about half-way up the trellis, and two at the top. Luckily, we got some nice sunny days in the fall and freezing weather held off until my grapes ripened and got sweet enough to eat. Needless to say, his grapes sweeten off faster than mine and they end up with a higher sugar content at harvest.
