Sul serio, Nestea? Non Rivella? O è solo un titolo sfocato?

i think this is more about international popularity for a drink of each country of origin

and nestle is switzerlands biggest food company so it doesn’t sound completely wrong. Rivella on the other hand is pretty niche outside of switzerland.

I don’t think they go by company seat though since fanty is coca cola company, but maybe place of introduction/first market?
