Keurig Dr Pepper has released a new sugar-free formulation of its iconic soft drink. Using a combination of aspartame and acesulfame potassium, Dr Pepper Zero Sugar is being described as an addition to the aspartame-only Diet Dr Pepper, rather than a replacement. How is it? Dr Pepper famously has 23 unique flavors, and you can find lists on the internet that purport to reveal them all. I don’t know how accurate these are (carrot, really?), but as a frequent Diet Dr Pepper drinker, I’m very familiar with what they create.
