There are lots of different ways of training grape vines so it depends on what you are aiming at. I just prune mine in winter to a central cordon, and in summer take the shoots off a few leaves beyond the flowers to stop it taking over the world. I gather you can train in a new leader every year and it might be more productive that way, but the way I do it is simple and seems to work.
I have planted a mix of edible hedge plants along the road. The sheep keep it trimmed on the other side Rosa rugosa have lovely large hips, I'm hoping that the japanese quince plants will grow nicely there too.
