I know formulations can differ from country to country but don’t understand why the same drink in the same country can taste so different depending on packaging.
In: Chemistry
A soda fountain is mixed on the spot with water and carbon dioxide provided by the restaurant, with concentrated flavoring provided by the beverage company. Even if the soda fountain avoids big variations in how the soda is mixed, you still have different tap water that could affect taste. You can filter it to try to make it more consistent but there’s still a lot of variation possible.
Cans are actually lined with plastic on the inside so you shouldn’t have much flavor added to the drink by the container, or if you do it shouldn’t be too different from a bottle. But you can still taste the metal of the can on your lips. Bottles may let light in which can cause many changes over time, and carbonation levels could be different too.
