A 1901 study showed that the back of the tongue tasted the bitter, the sides the sour, the front the sweet, and so on. Spicy was not one of the 4 flavors described in that study . . . The newer studies of the tongue with regard to taste have shown that the entire front, top, sides, and back are pretty much equal in what they taste; however, it has been shown that certain parts of the tongue are first to be able to taste certain flavors. But once there is enough concentration of a substance to be able to taste it at all, all parts of the tongue taste the substance pretty equally. The basic 4 "tastes": sweet, sour, salty, and bitter, are present all over the tongue.
