I never thought about making vinegar with them. I'll have to research that.
We have a couple large scuppernongs that we planted about 25 years ago. They put off lots each year. We also have wild black and bronze ones that come up wild everywhere on our property. I am always digging them...
I've been pulling it or digging it out since we moved here in 1992. No matter what it comes back. Easier to remove when small. I find it rather stinky and itchy and the smell should repel something.
