"The second ingredient, caramel coloring, gives the drink its distinctive dark brown color. There are four types of caramel coloring — Coca Cola uses type E150d, which is made by heating sugars with sulfite and ammonia to create bitter brown liquid. The syrup’s other principal ingredient is phosphoric acid, which adds acidity and is made by diluting burnt phosphorus (made by heating phosphate rock in an arc-furnace) and processing it to remove arsenic." Hmmm... arsenic I'd rather there were no lethal poisons at any point in the production process. I'm never drinking another glass of Coca-Cola. I'm not touching PEPSI either.
