Dr Becker is one of the all-natural varieties made by Blue Sky in Santa Fe, New Mexico. It is available at Dominick’s in Rolling Meadows, IL, and probably many other places around the country. So how does this all-natural Dr taste? Horrible! The best thing that this beverage has going for it is the fact that its pull-tab is blue (and how exciting is that?). Dr Becker gets a one-half Dr Pepper can rating.
