Diet Coke and Coke Zero are very similar beverages.
They’re both cokes. They’re both sugar-free.
The main difference is that one is marketed towards women in a nice silver tin, with the oh-so-feminine-word ‘Diet’ scrawled in front, and the other is for blokes who take no sugary crap.
But it turns out that there’s a slightly bigger difference than just the tin.
Because the two drinks apparently don’t taste the same, despite both being sugar-free Coca-Colas.
Well, Coke Zero is supposed to taste like full-fat coke, while Diet Coke actually has a different taste altogether.
And the only difference is one single ingredient.
Citric acid – commonly known as lemon salt – is exclusively used in Diet Coke and is a preservative which has a tart-taste.
Coke Zero, on the other hand, uses sodium citrate to better mimic the full-fat coke taste without the sugar.
So Diet Coke ends up tasting a bit sharper, a bit more refreshing while Coke Zero has all of the sugary flavour of normal Coke, without actually containing any sugar.
