Beverage packaging choices depend on drink type and preservation needs
Aluminium cans and glass bottles serve different functional purposes for maintaining the flavour and carbonation of various drinks, according to the Times of India.
The choice between aluminium cans and glass bottles for beverages is determined by more than just portability or convenience, according to a report by the Times of India.
Aluminium cans are used for fizzy drinks like beer and cola because they can hold internal pressure and prevent carbon dioxide from escaping. This helps maintain the carbonation required for these beverages.
Cans also protect beer from light, which can cause an unpleasant smell. While glass bottles can be tinted to block light, aluminium provides a complete barrier.
In contrast, wine and whiskey are often packaged in glass because it is chemically stable and does not react with the liquid. The University of Florida's Packaging Implications for Wine and Alcoholic Beverages states that glass offers protection against gases and vapours to preserve quality.
For wine, preventing oxygen exposure is crucial to maintaining aroma, colour, and flavour. Similarly, the inert nature of glass prevents unwanted flavours from being imparted to whiskey.
While canned spirits and ready-to-drink whiskey cocktails exist, traditional glass bottles remain popular for communicating premium value and heritage.
