grape for a polytunnel

i'm thinking of growing a grape in my large polytunnel (15 foot by 30 foot), I've grown grapes in the past in green house, but that was insulated during winter, the polytunnel wont be.

I was thinking an outdoor variety? can anyone recommend a red/black grape for a polytunnel (will have to be a dessert grape, i'm not making red wine!)

    A grape copes very well with freezing in the winter. Only trouble with a polytunnel, is when the grapes are ripening, it may be too humid, and it increases the chances of botrytis rot. If you can give it enough ventilation, it will be ok.

    You don't stop doing new things because you get old, you get old because you stop doing new things. <3
  • I have double doors at both ends of the polytunnel, so ventilation shouldn't be a problem Muscat Hamburg sounds good, i'll have to google it  image
