I know some varieties of muscadines need more chill in Winter than even North Florida gets in order to crop well. My area is probably borderline for even the lower chill varieties. I saw a bunch of wild plants last year at the Lee county free mulch site on Pine Island and some others in Punta Gorda and Cape Coral on vacant lots. Never seen fruit on any local wild plants though. Maybe this year they will fruit after the relatively cold Winter.
If you want to try fuzzy kiwi, Vincent and Tomuri are the pair to try in South Florida, since they only need about 100 hours of chill. There are others varieties than need up to 800 chill hours. Kiwi vines get really thick and heavy, I saw one years ago in South Carolina that was so big the owner supported it with 6x6 posts over an area the size of a baseball infield. Forget fuzzy kiwis unless you have acreage. They grow like Jack's magic beanstalk.
In the tropics like Africa , and such they spray urea or pee to defoliate to force vines to go dormant
This is large scale viticulture , but you could do this by hand .
you would not want to water these during this period
There is a few things I know about it, and have saved, but as of today do not have the time to go digging for it
maybe in a couple days I will try.
you may want to contact rainn man here or read his posts as well.
there are also some breeder web sites (but not sure if they want much internet traffic.)
