What is the freezing point of Fanta?

We do not monitor the exact freezing temperatures of each of our products. However, our diet products freeze at a temperature similar to water, 32 degrees. Coca-Cola classic freezes at a slightly lower temperature, about 30 degrees. The pressure in an unopened bottle or can will cause the freezing point to be even lower. All diet beverages will freeze before their sugar counterparts. Sugars lower the freezing point of liquids. This means that the temperature must get lower than the normal freezing point of water before it freezes.
