Why do you say that, Chippy?
Does all the juice in the UK come from home-grown grapes?
When white grape juice vanished from the shelves many years ago i emailed the big supermarkets they said the crop had failed and as demand was so low they were not going to stock it again that was roughly nine years ago, i have checked online and 100% juice doesnt come up on ASDA ot Tesco sites so i assume its still scarce or they have never restocked it.
