As Passover approaches, Coca Cola has released Coca-Cola made with cane sugar then high fructose corn syrup. 

This product is available as of right now until Passover concludes

To make sure it's Passover Coca-Cola the bottle must have a yellow cap and or say for Passover, check the ingredients if you're not sure. 

This is unfortunately the only time you can get the original flavor Coca-Cola before the recipe swap in 1985 so buy it while you still can.
