Coke is actually very different from country to country and less so from state to state. This is because Coke uses local bottle companies and they might be using different water. The coke you buy at your local store is probably bottled somewhere close to keep shipping costs down.
If you're a fan of Dr.Pepper, you'll notice they have 2 different bottles based on where you buy. That's because in some regions, Dr.Pepper uses Pepsi for bottling and in others it uses Coke bottlers.
It's not only the water, there are more differences like high fructose corn syrup versus other sugar forms.
As far as I know, the HFCS vs Sucrose is unlikely to be the reason for the difference in taste. I'm basing that off this video: https://www.youtube.com/watch?v=NY66qpMFOYo
TLDR: carbonic acid breaks down sucrose to glucose/fructose anyway
Isn't Coca Cola water reverse osmosis filtered?
The taste of local water should be irrelevant.
They don't do full reverse osmosis to the purest extent. There are still quite some minerals left. That's actually better for the end product
I can't speak for coke, but for bottled water, they often add minerals back in.
Honestly, the water is just a guess since the taste is different and the syrup comes directly from Coke. In other comments here, people mention the cans used but I’ve had Coke in glass from different countries taste different.
