How fascinating. I will check out the link when I get home from work. Thanks for posting it!
My family has been growing muscadines for generations out here in eastern North Carolina. It’s good to know what is considered such an ‘old fashioned’ grape is so healthy for you!
One thing you’ll come across eventually if you read much on this: Muscadines and scuppernongs require very little care, and not many pests bother them, and grapes produce resveratrol as a defense against fungus diseases. It’s thought that, since muscadines often aren’t sprayed at all, that they produce more resveratrol fighting off fungi with no assistance from man. - So, it might be best to not spray unless absolutely necessary.
A lot is this is probably still being studied, but I’ve seen that stated in several different articles.
