<3 serbia
best investigations i know of determine that the nation originated from a tribe from what is now central-eastern germany, the "sorbs" as best i understand it
turns out they didn't invent distilled drinks but they definitely discovered that plum brandy is the majestic king of ethanol containing beverages, more than 8 out of 10 samples of random home-made rakia in serbia are better than any spirit you ever drank
anyway, point being, serbians are among the smartest people in the world, and the whole balkans is not far behind them
