The reason why Coke and Pepsi tastes different around the world is because Coke and Pepsi only manufacture the syrup. The dilution and bottling of the drink is licensed to different companies around the world and they add there own shit to the mix. I personally think UK versions are the best tasting.
i love the coca cola cans they have for Arabic countries. I remember when i worked in the airport, i used to steal them from the flight kitchen and they had the same ones in Tunisia when i was there. The can is a brighter red and the Coke seems to taste nicer lol
I've noticed also that Coke from other countries tastes better than the American version of Coke. I mean.. the Mexican Coke that they serve in restaurants in La Villita >>>>> Coke in regular stores. Then again.. fountain Coke is much better than coke in a can.
