Yes Iddee, That's what I understand, they are a variety of Muscadine.
I love mowing right now. I grab a hand full from the vines as I go buy.
The grass around my vines is well manicured right now.

Funny, I was calling local nurseries a couple years asking for Muscadines. The lady on the phone said hang on I'll ask. She yelled out to another lady and the other lady response was " we have Scuppernongs " the lady on the phone busted out laughing she thought the lady said "SUPERDONGS"
That was funny. Will always laugh thinking of her when I here that word.
