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
Variations in filling methods and bottling locations. Cans and bottles are filled in certain regions. Those factories can fill bottles based upon local preferences. My local soda bottler has had numerous warnings from a major bottler due to filling cans with a higher percentage of co2 than the “home office” specifies. Metal cans are filled locally in my city, but bottles come from a different state. Different water and shipping conditions (heating, co2 levels, etc) can affect taste. Unrefrigerated warehouses and length of storage can also affect teste.
Fountains have similar difficulties. The syrup concentrate is from the same factory, but they use local filtered water (which may have a different taste) and pressurized co2 bottles. The pressure in the co2 bottle can be misadjusted or the tank could be low. Also, the fountains add ice into the cups, and the ice can have off flavors or smells from the facility’s ice machine.
