No wine this year we try to make a few gallons every year but me and the kids have been eating them as fast as I harvest them. I'm not a drinker but I love the fruity flavor of some homemade Muscadine and blackberry wine both.
Weedhopper I agree with Thomas water is the key to a good harvest even on wild vines. Wait until the plants are dormant before transplanting. Since you will be damaging some roots in the process they won't be able to provide as much water to the vine as before they where dug up. Pruning 1/3 of the vine back or more will give them a better chance to survive and get established.
