Mexican Coke, which uses cane sugar, comes in a glass bottle, but you can also get US coke presumably with corn syrup in a glass bottle and some people do think it tastes better.

> Mexican Coke, which uses cane sugar

This is at least partially a myth.

Here's a study which found no sucrose in Mexican coke: https://onlinelibrary.wiley.com/doi/full/10.1038/oby.2010.25...

Though, it is complicated because there are multiple bottlers making multiple different coke products, and even the same bottlers could shift what sweeteners they use over time, presumably based on pricing.
