Grape-flavored anything is an exclusively American treat.
The purple Skittles in other countries are actually black currant-flavored, Business Insider reported.
In fact, grape artificial flavoring used to be found in Germany and Austria, but it was being marketed as “orange blossom essence,” according to PRI. Those countries didn’t have Concord grapes, which is what grape-flavored things are based on – so only Americans will associate that smell and flavor with grapes.
