I couldn't tell from the Strange Maps write-up whether those belts were based on where which alcohol was produced, where the most was sold? consumed? exported? There must be more info, but I wasn't finding any of the data or back-story to the classifications.
I think it's more cultural, as in "what is consumed" and "where is there a culture of ____". There's another version linked in the Strange Maps article.
