ELI5: Why does the temperature of a food drastically change how it tastes?

For example, warm beer tastes very different than ice cold beer. Cookies fresh out of the over taste different from the same batch of cookies that sat at room temperature for an hour.

Our tongue's taste buds have tiny microscopic channels (called trpm6) which send a signal to our brain when it comes in contact with 'taste molecules' which are then translated to a specific taste sensation. The reaction of the channels are much more intense when the food has a higher temperature so it sends a stronger electrical signal to the brain. Naturally, the opposite is in effect for colder consumables as the channels respond much slower. In conclusion, hotter food is more tasty than colder alternatives.

 (note that TRPM5 is only used to signal sweet and bitter tastes)
