Interesting...I’ll have to let my son know. He likes Zero Coke, not sure if he’s had a diet Coke. I used to buy the caffeine-free Coke, it has a gold label. Hard to find, though.
Thank goodness I have no problem purchasing the caffeine-free Coke here in Panama.
There is no difference in taste with the original.
On the other hand, I find diet cokes to be foul tasting to include the coke with no caffeine and no sugar.
When I discovered Panama sells the above, I purchased a case. It was all I could do from pouring it down the sink.
