Coke Zero: Tastes Like Lime?
I have this weird problem with Coke Zero (that’s the American Coke Zero, which may be different from international branding). This version of Coca Cola differs from Diet Coke because it contains a different sweetner: Acesulfame Potassium (also known as Acesulfame K) instead of Aspartame. The problem is, it tastes like lime to me.
To put this in perspective: for me Coke Zero tastes and smells like Lime Diet Coke. Seriously. I can’t tell them apart. I’ve also tasted this effect in Diet Coke with Splenda, another drink that contains a different combination of sweetners that includes Splenda and Acesulfame K. It’s like Diet Coke with a slight limey flavor.
I can think of a couple of reasons for this. One is that Acesulfame K really tastes like lime to me for mysterious reasons. I’ve never tasted the sweetener alone, so I don’t know for sure. The other possibility is that I can’t taste Acesulfame K at all, meaning I’m picking up too much of the other acid flavors in the drinks.
Anyone else have experience with this?
