Sorry to be the bearer of bad news but grapevines tend not to do very well in pots since the root system is extensive and likes to wander down deep. (this is the reason established vines don't need watering.)
The other problem is vine weevil (named because vines are one of their favourites) that flourish in pots.

A potted vine will need regular treatments against it.
If you have a really large pot you may get away with it but it would have to be pretty big I'd say.
Another plant better suited to a container may save you some trouble.

If you are determined to press ahead choose the variety you like. An over vigorous vine in the ground will grow less vigorously contained while a less rampant grower will be happier longer.
As I say sorry to be a party pooper but my comment is based on experience.
