First of all Tari's Burgundy is a hybrid between vitis shuttleworthii (Calusa grape) and vinifera. The breeder mistakenly thought that the native shuttleworthii was a native muscadine. But it is clear the fruit, leaves, early ripening etc. is very similar to shuttleworthii, which is native to south florida. In my opinion is the best wild grape I have found. The berries of shuttleworthii are similar to store grapes but slightly better tasting, though the texture is terrible when ripe (muscadine type of gooey texture, though is crisp and edible when green). Though it does have a bit high acidity, this is usually toned down when hybridized. It also ripens very early as indicated here, which is why it only grows in Florida and suceptible to cold.
Almost every grape variety I tried in South Florida died on me even Florida varieties like Blanc Du Boise. I'm just not good at spraying and its too wet and humid. However I have finally had success with Z86 seeds I have gotten (zehnder grapes). This grape is actually 6% muscadine so the seeds are a little over 3% muscadine, though mostly gets disease resistance from aestavalis, the small drop of muscadine seems to really improve toughness as the grape is over half vinifera (cabranet sauvignon parent). This year I have some z86 x taris burgundy seedlings starting to grow.
My tari's burgundy rooted well from cuttings, but was slightly suceptible to anthracnose so the young cutting died. With my zender seedlings about 20% or so die from anthracnose and I Just keep the ones that have bullet proof disease resistance. I also bred a seyval blanc x shuttleworthii which is much tougher than Tari's Burgundy. I also had a CA8-15 at one time which is villard blanc x shuttleworthii. It is tougher than Taris because it isn't suceptible to anthracnose but it is suceptible to rust fungus (taris probably is as well). My seyval blanc x shuttleworthii seems to resist everything. CA8-15 is good for fresh eating but wine quality is not nearly as good as Taris and it is harder to root (though will root with some difficulty).
The actual muscadine hybrids like southern home, dunstan's dream etc. are good options too. But my Seyval blanc x shuttleworthii is actually tougher than muscadines like southern home. Though Southern Home survives pretty well down here it takes several years to dig its roots in deep and get established. I never had Dunstan's Dream but would like to get it. One of the muscadine/vinifera hybrid that Dunstan produced is in the background of the Z86 Zender hybrid. Wheras Dunstan's dream is straight up half muscadine half vinifera.
