More and more is being learned about antioxidants. And most fruits or vegetables with intense color and/or intense flavor are good sources of antioxidants: blueberries, cherries, elderberries, garlic, onion, muscadines, other dark grapes. Some varieties of the old, southern muscadine are thought to be perhaps the richest source of all.
That is really interesting. I have three vines on the edge of my property line here in NC.
I have one Scuppernong vine, one Black Noble vine and a coastal “James grape” vine. My dad usually makes wine from them...I will have to let him know!
