It’s an apple to fruit comparison, then: More apt would be picking carbonated soda drinks, maybe. Or pick out a single kind of wine from a single vineyard.

I’m just a bit salty on comparing such a giant category like European wine or beer to a single company‘s soda.

Specifically colas as opposed to all carbonated drinks should count.

I don't know if generally all sweetened carbonate drinks are mainly American, but I wouldn't be surprised.

That's fair. Most of the popular soft drinks today were invented in the US - Pepsi, Sprite, Dr. Pepper, 7-up, Slice, Dr. Pepper.
