Finally, because it is well established that bright sunlight can harm the taste of beer, it would appear reasonable to conclude that the brown-glassed Singha bottles protect their contents better than the clearer green glass used by Heineken. For tropical markets such as Thailand where product can be exposed to the harsh rays of the sun during transport or otherwise, the marketers at Heineken would be well advised to either darken the color of their glass containers or incorporate some ultraviolet protection in their bottles to avoid this degradation of their product in these types of markets.
