Lately I've gotten into drinking zero calorie gatorade and there seems to be some strange food science happening here. I've noticed that if I drink it cold, it can be quite tasty depending on the flavor, but when it gets to be a little bit lukewarm, the flavor disappears completely and it just tastes like drinking sweat. Usually I can taste foods better when the product is warmer, not colder. For instance yogurt and ice cream are tastier if they're just slightly melted - the coldness normally mutes the flavor a little bit. But it's completely backwards with gatorade (and probably some other sports drinks as well). Very strange how the temperature/taste relationship can be flipped on it's head like this.
