The reason Hersheys tastes like vomit actually isn’t because of the (lack of) cocoa. It’s because they use intentionally soured milk in their chocolate.
Basically, a company as large as Hershey strives for consistency instead of quality. And that means they need a consistent source of milk. The problem is obviously that milk sours fairly quickly. So rather than using inconsistent milk (which may be in various states of souring), they use butyric acid to intentionally sour the milk. And butyric acid is also found in vomit.
So when Europeans try American chocolate, they’re often disgusted by the taste. Americans have grown up expecting that tangy taste in chocolate, but Europeans haven’t. So it’s all they focus on, and it inevitably ends up with them thinking that all American chocolate just tastes like vomit.
