the project wouldn't be to big ..i like that idea of a vineyard… 
Check the rules for them they might have changed in your favour since I looked into things in 1996 .
If turns out to be a real good prospect run the vines north to south where possible so the rows get even sunlight on each side to ripen the grapes .
Look for someone to process them for you initially as that is the cheapest option when you start up .
Mr& Mrs HMCR will also be very interested in your venture.
My pal Paul demanded we plant his east to west despite me advising him otherwise when we helped him plant 4,000 vines .. at his second harvest time he couldn't understand why the grapes on the north side were almost non existent .
Paul contacted a French vineyard after making on line enquiries about red & white grafted cuttings 7 drove to the vineyard to collect them as this was the quickest surest method of delivery . I heeled the cuttings into damp sharp sand as soon as they arrived at the small holding as him and his lass were totally knackered after the round trip drive.
It took three days to plant all the vines and a darn sight longer to erect the suport posts and straining wires.
He should have set the posts and wires long before he got the grafts and have used a two man power auger to make the holes for the posts as each post was dug in by hand .
Whilst he'd taken the turf off the rows he failed to rotovate them so each cutting had to be dug in 11 inches deep by hand the hard way .
