Can vinifera grapes always be distinguished visually from non-vinifera grapes?
At one end of the taxonomic spectrum, for example Muscadine, it is obvious that the non-vinifera grape is different. The Muscadine grape clearly does not "bunch"; it's just loose balls hanging from the vines.
However, based on the pictures of Concord and other table grapes, including some Concord crosses, it looks like they are very close visually; I could not tell them apart by simply looking at the images.
Your thoughts please.
