alt Hacker NewsFun fact: a lot of people think artificial grape flavoring doesn't taste like grapes. And that the "Welch's concord grape jam" variety of jams is artificially flavored.
Nope, that's just what some grapes taste like. There's a Korean variety, and Concord at least. Wiki says it's this: https://en.wikipedia.org/wiki/Vitis_labrusca
The grapes that grow in my back yard are Concords, and that shouldn't be surprising because Concord is a couple of towns over.
They taste just like Welch's.
