Brilliant question!
Here's what I found:
"You don't. Seedless grapes are grown from rootstock of other seedless grapes, either by grafting or simply planting cuttings from them. The initial 'seedless' variety (they all have minute traces of seeds) is grown by cross pollinating a seedless variety with a seeded one. Where the original came from I haven't a clue, but probably from some enterprising vintner who decided they'd make great snacks as well as wine."

It is the same with Tories. Where do they come from?

they use propagation http://en.wikipedia.org/wiki/Propagation

Like Navel Oranges (a fruit I know about) they are probably grown from clippings of a mutant plant.

well once the vineyard grows, it produces grapes every year.

It takes about 5 years for a grape vine to produce grapes. So when you harvest the grapes, you pick them carefully, so you dont damage the grape vine.

Grape vines, if they are in a good enviornment, which would be fairly warm and sunny, and if they don't get a blight, can live for hundreds of years. Also, to plant a new vine, all you need is a vine from another plant. You can also graft one type of grape vine onto another to get multiple types of grape on the same plant, just as can be done with pears and apples. There will always be seeded grapes. They are hearty enough to be considered a weed. These are bred to make seedless varieties.
