ELI5: Why does coca cola taste so much better in a glass bottle as opposed to plastic bottles and soda fountains?

Glass is far less permeable than plastic, so glass bottles will have that fresher fizz, and cans probably impart some metallic/metal oxide flavour. Basically glass tastes best because it has the perfect fizz, and the least altered taste.
