What should be the main method of physical attachment for the cordon to the wire itself? Is it the tendrils from the vine trained to grip the wire? Or is the cordon coiled around the wire in a helical shape as it grows? I think I notice the coiling of the cordons in your videos, but I'm not certain.
You should tie the vine to wire with jute twine or plastic ties until it grips the wire itself. At first it will grip with tendrils. As the vine grows the side shoots will come out to both sides and these will balance it on the wire. Don't wrap the vine around the wire (although it sometimes happens) because as the vine grows it will grow into the wire which causes damage and difficulty if you ever have to remove the vine.
Your videos are quite good, but I think this one stands out. I'm looking for the "best" variety for home gardening table grapes in s/w Florida. I've never tasted any of the species, but love all fruit. Definition of "best": -high disease/pest resistance -self fertile -fully edible, except for seeds -darker in color (polyphenols) -flavor, doesn't have to be super sweet, just not bitter or sour What one or two species would you recommend? I've heard a lot about Lane and Ison, but this one may be it based on your videos. Ripening in a staggered fashion would be a bonus.
