Coca-Cola Co. offers a kosher version of Coke that uses sugar (look for bottles with yellow caps), often available around Passover. Mexican-made Coca-Cola, which also uses real sugar, can sometimes be found in the United States, and fans pay a higher price for it. One Dr Pepper bottler, Dublin Dr Pepper, has been making the soft drink with sugar since 1891, in the drink's home state of Texas.
