Methyl anthranilate is present in pretty high concentrations in the fruit of grapevines descended from Vitis labrusca, a native grape species of northeastern North America. Concord, Niagara, and Delaware are some of the commonly available grape varieties that are crosses with v. labrusca and the "grapey" Welch's taste that some North Americans enjoy and most Europeans loathe comes mostly from the methyl anthranilate.

Just sayin'
