I’ve definitely experienced this. Not so much with coke, which I don’t care much for either way, but lemonade. Lemonade out of a glass bottle is top tier, followed by the post-mix syrup served at bars. Out of a can though is just not as nice. I don’t care if there’s no rational reason for that to be the case (the post-mix at least might be a different recipe, but Sprite in a glass is surely the same as Sprite in a can).

Yeah, I bet that the glass works for some folks. My friends and I played with some blind tastes test, and some people couldn’t tell the difference, and other could tell 100% of the time with ease.

My guess is that the taste difference is due to the fact that Mexican Coke has so much glucose that it easily throws a OTC glucose monitor into an overload error state.
