Anyone who has ever taken a shot of hard liquor (tequila, brandy) can tell you: it burns on the way down. But it's not the alcohol itself that's burning your throat. Instead, the ethanol in the liquid is making your throat's VR1 heat receptors (left) more sensitive, prompting them to perceive your own body temperature as hot.

Normally, the VR1 receptors activate at 42° Celsius, but alcohol lowers this threshold to around 34° C, which is 4° C less than your bodies regulated temperature.
