Not quite true, especially for bottles in the EU. They usually just ship one concentrate pulver per soda type, which is one ingredient of many. Most ingredients are sourced elsewhere throughout the world or locally.
As for syrup for soda stations in restaurants, I don’t know anything about the production process of those.
It’s bottled locally in Germany as well. However all bottling plants that do, are owned by the bottler that is exclusively bottling Coke and other Coca-Cola Company products (and some others such as the energy drink Monster, but Coca-Cola has a stake in them).
