We have had countless requests from customers over the years to make a diet cola. We were reluctant to make one unless it was up to the high standards of our regular sodas. Finally, after years of experimenting with alternative sweeteners, we are happy to announce Rocky Mountain Soda’s first zero calorie option; Denver Diet Cola! We stayed true to our roots and crafted a classic, crisp cola flavor using our natural cola extracts and balanced the sweetness provided by organic stevia and natural erythritol that is sure to please even the most concerning diet cola drinker. And to satisfy all the requests, we even added natural caffeine!
