I don't see any description claiming these countries to be top drinkers. That's solely your interpretation.

Maybe the author simply just felt like using these five countries for this piece of art, and I see nothing wrong with that. SATW isn't just stereotypes and portrayals of real-life events. Sometimes, it's also the author's creative imagination.
