Coca-Cola is one of the most popular drinks in the world and is known for its unique and unmistakable taste. However, many people claim that Coca-Cola tastes even better when it is in a glass bottle rather than a can or plastic bottle. But what is the reason behind this difference in taste?
Although Coca-Cola claims the recipe is the same across all its packaging, recent research shows that science may explain why the drink tastes different in a glass bottle.
Sara Risch, founder of food and packaging consultancy Science by Design, explained that even though Coca-Cola liquid has the same formula for all products, the packaging used to store the drink can affect the taste.
This is because in cans made of aluminum, the coating contains a polymer that can absorb small amounts of flavor. In the case of plastic bottles, the material of the bottle can transfer small chemical substances, which can also interfere with the flavor of the drink.
Why does Coca-Cola taste better in a glass?
There are several reasons why Coca-Cola may taste better in a glass bottle compared to other packaging.
The first reason is that glass is less permeable than other materials such as plastic or aluminum, which means the drink is less susceptible to losing carbon dioxide (CO2) during the storage process.
CO2 is an important element in the taste and texture of Coca-Cola, and excessive consumption of it can affect the quality of the drink.
Additionally, glass is inert, meaning it does not react chemically with Coca-Cola. On the other hand, some packaging can release chemicals that can affect the taste of the drink.
