Scuppernongs taste like beefed-up Concord grapes. The skin is leathery and tannic, and it's riddled with seeds, but the meat is fragrant.
My favorite skipper claims that they are inedible, but I think he's wrong on this one.
A quick perusal of the interwebs shows a LOT of scuppernong-related music. I cannot recommend any of it.
On an earlier draft, I linked some YouTube Scuppernong highlights: experimental plonk-plonk music, an chaotic atonal jazz composition, an odd spoken-word performance, some only-for-serious-fans-of-high-and-lonesome bluegrass.
These were videos with maybe a couple of dozens of views and no comments after years of waiting in the ether. Linking to them was akin to finding something in the fridge and offering to your buddy, saying, "Here, sniff this, it's awful!"
