Just Bought a Grape Vine. How Do I Look After It?

Hey Folks,

I'm pretty new to gardening. Currently growing: Courgettes, pansies, sunflowers, beetroot, lilies, strawberries, raspberries, red berries, blackberries and tayberries. So far, they're all doing well apart from the pansies who aren't doing anything at the moment.

Anyway, more to the point: Today I saw this gorgeous baby grapevine and really wanted it. The type is: 'Vitis Vinifera Regent' and the only information given is that it must be in a sunny position, it flowers in May, it must be pruned Dec - Jan and harvests in Sept/ Oct.

It's currently in my greenhouse (I live in the UK so I don't want it going outside) in a large pot with multi-purpose compost. Is this the incorrect thing to do? How do I look after it properly? I want him to succeed.

Please help! Any advice would be greatly appreciated
