I wish I had put 15 feet between each of my grapes, maybe more. The ground where they grow sure makes 'em grow large.
I know a wine grower that puts his grapes on 5 foot centers (good soil), but I think they just shade each other out. That might be a little close.
The same grower allows 11 feet between rows.
I am also growing Triple Crown blackberry. Originally put around 7 feet between each plant, but am now filling each space in with one more bush. Seems like a waste of space unless I do. I want a solid hedgewall of these babies, not half plant, half air!
They are a single row, but for mowing purposes and sunlight gathering ability, I would probably allow 10 feet to the next row, maybe more.
Doesn't matter a whit how far you space raspberries. They are just going to take over your property anway!

For distance between rows consider how phat each vine may grow. Grapes can easily take up 3 feet of room besides the row they are planted in. Add some room for a lawnmower to get up and down, add in the allowance for the other row, then you have a good picture of distance to leave. If you bunch your rows really tight, they end up shading each other out, starving for sun. If you leave 15 feet between rows, it might be too much, but the rows will never shade each other, thus permitting maximal sunlight to reach all foliage, for maximal harvest.
Your rows should ideally run north to south too to get boths sides of your plants evenly exposed.
thank you, plumfun, very much - this is exactly the information I needed! I would have planted them too close, just a riding mower distance between but now understand the need for the vines to have as much sun exposure as possible. I appreciate your taking the time to help.

8 feet between vines is a good average and will work well with most grape varieties, though a few like Himrod and Niagara that are highly vigorous will fill in ten feet between vines. Between rows, as plumfun says, the space can be wider to accomodate equipment and the tendency of the vines to grow out into the aisles. My personal preference in row orientation is to run them parallel to the prevailing winds where possible. That way, if there is rain at ripening time the vines dry faster and there is less fruit cracking.
Of course this is all in The Grape Grower (shameless plug
